Exposure to obinutuzumab does not affect outcomes of SARS-CoV-2 infection in vaccinated patients with newly diagnosed advanced-stage follicular lymphoma.

URBAN is a multicentric, ambispective study evaluating the effectiveness and safety of obinutuzumab-based immuno-chemotherapy and maintenance in patients with untreated advanced follicular lymphoma (FL). The study began before the COVID-19 emergency declaration in Italy. It is currently ongoing for follow-up, and the enrolment timeline encompassed different stages of the pandemic, various vaccination roll-out phases and prevalence of SARS-CoV-2 variants. Outcomes of interest of the present sub-analysis included SARS-CoV-2 infection rates and COVID-19-related hospitalizations/deaths. At data cut-off, 86 (28.8%) and 213 patients (71.2%) were treated before and during/after the COVID-19 outbreak respectively; 294 (98.3%) completed the induction, 31 (10.4%) completed maintenance and 170 (56.9%) were still on maintenance. Overall, 245 patients (81.9%) received at least one SARS-CoV-2 vaccine dose: 13.5%, 31.4% and 55.1% received one, two and three doses respectively. We observed a substantial decrease in COVID-19-related mortality rates in pre- versus post-vaccination phases, along with a reduction in COVID-19-related outcomes due to the shift from alpha/delta to omicron variant predominance. No differences emerged between patients given maintenance or not, although the schedule was modified in 65% of cases. To our knowledge, URBAN represents the largest dataset of COVID-19-related outcomes in FL patients extensively exposed to obinutuzumab. ClinicalTrials.gov identifier: NCT04034056.

Differences of skin carotenoids and adherence to the Mediterranean Diet pattern in adults from Southern Italy and Dominican Republic.

BACKGROUND: The measurement of the skin carotenoids using the Veggie Meter® has emerged as a rapid objective method for assessing fruit and vegetable intake, highly recommended by the Mediterranean Diet (MD), which represents one of the healthiest dietary patterns, worldwide. This study aimed to examine differences in skin carotenoid content and degree of adherence to the MD pattern between two adult populations from Southern Italy and the Dominican Republic. METHODS: This cross-sectional study enrolled a total of 995 adults, 601 subjects from Italy and 394 from the Dominican Republic. All participants underwent anthropometric measurements and skin carotenoid assessment by Veggie Meter®. Adherence to the MD and lifestyle were evaluated using the Mediterranean Diet Adherence Screener (MEDAS) and the Mediterranean Lifestyle Index (MEDLIFE) questionnaires. Correlations between the skin carotenoid and MEDAS score were estimated using Pearson's correlation coefficient. Multiple linear regression models were created to determine variables that affect skin carotenoid score for both populations. RESULTS: Mean total skin carotenoids were higher in the Italian compared to the Dominican Republic population (342.4 ± 92.4 vs 282.9 ± 90.3; p < 0.005) regardless of sex (women: 318.5 ± 88.9 vs 277.3 ± 91.9, p < 0.005 and men: 371.7 ± 88.3 vs 289.5 ± 88.1, p < 0.005), and remaining statistically significant after age-adjustment of the Dominican Republic sample. Using the MEDAS questionnaire, we found a higher MD adherence score in the Italian than in the Dominican Republic population also after age-adjusting data (7.8 ± 2.1 vs 6.2 ± 3.7; p < 0.005) and even when categorized by sex (Italian vs age-adjusted Dominican Republic women: 7.9 ± 2.1 vs 6.3 ± 2.6; Italian vs age-adjusted Dominican Republic men: 7.7 ± 2.2 vs 6.0 ± 4.7; p < 0.005). Using the MEDLIFE test, total Italians presented a lower score with respect to the age-adjusted Dominican Republic population (3.2 ± 1.2 vs 3.4 ± 1.4; p < 0.05). In multiple regression analysis, skin carotenoids were associated with sex and negatively associated with BMI in the Italian population (sex: ß: 54.95; 95% CI: 40.11, 69.78; p < 0.0001; BMI: ß: - 1.60; 95% CI: - 2.98,0.86; p = 0.03), while they resulted associated with age and sex in the Dominican Republic population (age: ß: 2.76; 95% CI: 1.92, 3.56; p < 0.001; sex: ß: 23.29; 95% CI: 5.93, 40.64; p = 0.009). Interestingly, skin carotenoids were positively correlated with MEDAS score in both populations (Italy: r = 0.03, p < 0.0001, Dominican Republic: r = 0.16, p = 0.002). CONCLUSIONS: This study provides the assessment of the adherence to the MD and skin carotenoid content in adults living in Southern Italy and the Dominican Republic, showing a higher MD adherence score and a skin carotenoid content in inhabitants from the Mediterranean region. Our findings highlight the need to globally encourage fruit and vegetable intake, particularly in non-Mediterranean area.

External Training Load Monitoring and the Impact on Training Load Management in Collegiate Male Soccer Players.

ABSTRACT: Gdovin, JR, Galloway, R, Tomasiello, LS, Seabolt, M, and Booker, R. External training load monitoring and the impact on training load management in collegiate male soccer players. J Strength Cond Res 37(7): 1434-1439, 2023-Soccer is a physically demanding sport within the National Collegiate Athletic Association and continuously increases in popularity. To ensure athletes are adequately prepared for weekly physical stressors, coaches can use global positioning system technology to monitor external workloads and exercise intensity. These data can subsequently help coaches and practitioners better implement individualized training programs to ensure athletes are properly balancing the overreaching and overtraining paradigm. Therefore, the purpose of this observational study was to retrospectively analyze 3 consecutive seasons of external workload (total and high intensity distance) and injury data, which were derived from all training sessions and matches in 46 Division-I collegiate male soccer players. A coach's interpretation sought to provide practical insight into the functionality behind load management and how it prepares athletes for the physical stressors placed on them throughout a season. Two separate 3 × 3 repeated measures ANOVAs were conducted to determine differences between total distance and distance at high-intensity with an alpha level set at 0.05. Total distance between preseason and in-season ( p = 0.003), acute high-intensity distance ( p < 0.001), and chronic high-intensity distance ( p < 0.001) yielded significant differences. These results conclude the demands of each athlete change weekly and between seasons. It is recommended that sport coaches and practitioners develop individualized training programs by workload monitoring while considering variables such as a team's style of play, experience, position, role within a program, training intensity, and the length of time between conditioning sessions, practices, and matches.

New Direct Limit on Neutrinoless Double Beta Decay Half-Life of

The Cryogenic Underground Observatory for Rare Events (CUORE) at Laboratori Nazionali del Gran Sasso of INFN in Italy is an experiment searching for neutrinoless double beta (0νßß) decay. Its main goal is to investigate this decay in ^{130}Te, but its ton-scale mass and low background make CUORE sensitive to other rare processes as well. In this Letter, we present our first results on the search for 0νßß decay of ^{128}Te, the Te isotope with the second highest natural isotopic abundance. We find no evidence for this decay, and using a Bayesian analysis we set a lower limit on the ^{128}Te 0νßß decay half-life of T_{1/2}>3.6×10^{24} yr (90% CI). This represents the most stringent limit on the half-life of this isotope, improving by over a factor of 30 the previous direct search results, and exceeding those from geochemical experiments for the first time.

Disrupting LXRα phosphorylation promotes FoxM1 expression and modulates atherosclerosis by inducing macrophage proliferation.

Macrophages are key immune cells for the initiation and development of atherosclerotic lesions. However, the macrophage regulatory nodes that determine how lesions progress in response to dietary challenges are not fully understood. Liver X receptors (LXRs) are sterol-regulated transcription factors that play a central role in atherosclerosis by integrating cholesterol homeostasis and immunity. LXR pharmacological activation elicits a robust antiatherosclerotic transcriptional program in macrophages that can be affected by LXRα S196 phosphorylation in vitro. To investigate the impact of these transcriptional changes in atherosclerosis development, we have generated mice carrying a Ser-to-Ala mutation in myeloid cells in the LDL receptor (LDLR)-deficient atherosclerotic background (M-S196ALdlr-KO). M-S196ALdlr-KO mice fed a high-fat diet exhibit increased atherosclerotic plaque burden and lesions with smaller necrotic cores and thinner fibrous caps. These diet-induced phenotypic changes are consistent with a reprogramed macrophage transcriptome promoted by LXRα-S196A during atherosclerosis development. Remarkably, expression of several proliferation-promoting factors, including the protooncogene FoxM1 and its targets, is induced by LXRα-S196A. This is consistent with increased proliferation of plaque-resident cells in M-S196ALdlr-KO mice. Moreover, disrupted LXRα phosphorylation increases expression of phagocytic molecules, resulting in increased apoptotic cell removal by macrophages, explaining the reduced necrotic cores. Finally, the macrophage transcriptome promoted by LXRα-S196A under dietary perturbation is markedly distinct from that revealed by LXR ligand activation, highlighting the singularity of this posttranslational modification. Overall, our findings demonstrate that LXRα phosphorylation at S196 is an important determinant of atherosclerotic plaque development through selective changes in gene transcription that affect multiple pathways.

A 57-year-old man with rapidly progressive pulmonary hypertension.

Pulmonary Tumor Thrombotic Microangiopathy (PTTM) is a rare condition associated with neoplastic disorders, predominantly gastric cancer, leading to pre-capillary Pulmonary Hypertension (PH). The pathologic mechanism involved is a fibrocellular intimal proliferation of small pulmonary vessels sustained by nests of carcinomatous cells lodged in pulmonary vasculature. Clinical presentation is nonspecific, including progressive dyspnea and dry cough. Diagnosis of PTTM is extremely challenging ante-mortem and prognosis is poor. Here we describe the case of a middle-aged man, without known previous cancer history. The clinical course was rapidly unfavorable, with progressive dyspnea and PH associated with hemodynamic instability, eventually culminating in patient's death. PTTM diagnosis was made post-mortem. PTTM should be considered in any patient presenting with unexplained PH, especially if it is rapidly progressive, poorly responsive to standard approaches or there is suspected history of malignancy. A prompt diagnosis of PTTM could help in bringing light into this still under-recognized condition.

Upregulated microRNAs in membranous glomerulonephropathy are associated with significant downregulation of IL6 and MYC mRNAs.

Membranous glomerulonephropathy (MGN) is a glomerulopathy characterized by subepithelial deposits of immune complexes on the extracapillary side of the glomerular basement membrane. Insertion of C5b-9 (complement membrane-attack complex) into the membrane leads to functional impairment of the glomerular capillary wall. Knowledge of the molecular pathogenesis of MGN is actually scanty. MicroRNA (miRNA) profiling in MGN and unaffected tissues was performed by TaqMan Low-Density Arrays. Expression of miRNAs and miRNA targets was evaluated in Real-Time polymerase chain reaction (PCR). In vitro transient silencing of miRNAs was achieved through transfection with miRNA inhibitors. Ten miRNAs (let-7a-5p, let-7b-5p, let-7c-5p, let-7d-5p, miR-107, miR-129-3p, miR-423-5p, miR-516-3p, miR-532-3p, and miR-1275) were differentially expressed (DE) in MGN biopsies compared to unaffected controls. Interleukin 6 (IL6) and MYC messenger RNAs (mRNAs; targets of DE miRNAs) were significantly downregulated in biopsies from MGN patients, and upregulated in A498 cells following let-7a-5p or let-7c-5p transient silencing. Gene ontology analysis showed that DE miRNAs regulate pathways associated with MGN pathogenesis, including cell cycle, proliferation, and apoptosis. A significant correlation between DE miRNAs and mRNAs and clinical parameters (i.e., antiphospholipid antibodies, serum creatinine, estimated glomerular filtration, proteinuria, and serum cholesterol) has been detected. Based on our data, we propose that DE miRNAs and their downstream network may be involved in MGN pathogenesis and could be considered as potential diagnostic biomarkers of MGN.

SURGICAL CORRECTION OF LABIA MINORA HYPERTROPHY, A PERSONAL TECHNIQUE.

BACKGROUND: Labia minora hypertrophy is a congenital or acquired condition in which both labia minora (or more rarely only one) protrude beyond the edge of the labia majora. The authors present a surgical technique of volumetric reduction of hypertrophic labia minora, associated with lipofilling of the labia majora. METHODS: Between 2005 and 2014, 27 patients underwent surgical reduction of labia minora, as described by Altier and Rouzier. The indications for surgical treatment varied and were as follows: interference with sexual intercourse; poor hygiene; difficulty wearing tight-fitting pants; difficulty while performing sporting activities such as cycling; aesthetic complaints. The surgical resection was associated with fat graft injection in labia majora in order to protect and cover the labia minora. The mean follow up was 1 year. RESULTS: The labia majora, increased in volume and firmness, cover and protect the labia minora slightly hypertrophic or surgically reduced. All patients reported an improvement in comfort, aesthetic appearance, when wearing close-fitting clothes and an improvement in their sexuality. In one case we recorded a "recurrence", with an increase of dimensions in width of labia minora, still lower than the preoperative situation but greater than the immediate postop. CONCLUSIONS: The reduction of labia minora hypertrophy with conservative techniques allows achieving excellent results in terms of aesthetics and functionality. The simple lipofilling of labia majora allows preserving and protecting the labia minora through a volumetric increase of the labia majora.

Psychotherapeutic and psychosocial interventions for managing stress in multiple sclerosis: the contribution of mindfulness-based interventions.

Depression or anxiety in multiple sclerosis (MS) has been linked to a more severe course of the disease and higher numbers of relapses, in addition to poorer treatment adherence and exacerbated immune system dysregulation. Recent investigations indicate that psychotherapeutic interventions for stress management, such as mindfulness-based interventions (MBIs), could improve quality of life, depression, anxiety, and fatigue in MS patients. Mindfulness fosters the ability to slow down and observe experiences as they truly are, which improves affect regulation. Mindfulness is acquired through training; its advantage over other psychotherapeutic interventions is that effects may remain over time, since cultivating mindfulness depends on regular practising of abilities learned during training. The objective of this article is to review the current evidence of psychotherapeutic and psychosocial interventions, including MBIs for stress management, and their beneficial effects on MS patients.

Landauer's Principle in Multipartite Open Quantum System Dynamics.

We investigate the link between information and thermodynamics embodied by Landauer's principle in the open dynamics of a multipartite quantum system. Such irreversible dynamics is described in terms of a collisional model with a finite temperature reservoir. We demonstrate that Landauer's principle holds, for such a configuration, in a form that involves the flow of heat dissipated into the environment and the rate of change of the entropy of the system. Quite remarkably, such a principle for heat and entropy power can be explicitly linked to the rate of creation of correlations among the elements of the multipartite system and, in turn, the non-Markovian nature of their reduced evolution. Such features are illustrated in two exemplary cases.

Beneficial effects of a semi-intensive stroke unit are beyond the monitor.

BACKGROUND AND PURPOSE: Precise mechanisms underlying the effectiveness of the stroke unit (SU) are not fully established. Studies that compare monitored stroke units (semi-intensive type, SI-SU) versus an intensive care unit (ICU)-based mobile stroke team (MST-ICU) are lacking. Although inequalities in access to stroke unit care are globally improving, acute stroke patients may be admitted to Intensive Care Units for monitoring and followed by a mobile stroke team in hospital's lacking an SU with continuous cardiovascular monitoring. We aimed at comparing the stroke outcome between SI-SU and MST-ICU and hypothesized that the benefits of SI-SU are driven by additional elements other than cardiovascular monitoring, which is equally offered in both care systems. METHODS: In a single-center setting, we compared the unfavorable outcomes (dependency and mortality) at 3 months in consecutive patients with ischemic stroke or spontaneous intracerebral hemorrhage admitted to a stroke unit with semi-intensive monitoring (SI-SU) to a cohort of stroke patients hospitalized in an ICU and followed by a mobile stroke team (MST-ICU) during an equal observation period of 27 months. Secondary objectives included comparing mortality and the proportion of patients with excellent outcomes (modified Rankin Score (mRS) 0-1). Equal cardiovascular monitoring was offered in patients admitted in both SI-SU and MST-ICU. RESULTS: 458 patients were treated in the SI-SU and compared to the MST-ICU (n = 370) cohort. The proportion of death and dependency after 3 months was significantly improved for patients in the SI-SU compared to MST-ICU (p < 0.001; aOR = 0.45; 95% CI: 0.31-0.65). The shift analysis of the mRS distribution showed significant shift to the lower mRS in the SI-SU group, p < 0.001. The proportion of mortality in patients after 3 months also differed between the MST-ICU and the SI-SU (p < 0.05), but after adjusting for confounders this association was not significant (aOR = 0.59; 95% CI: 0.31-1.13). The proportion of patients with excellent outcome was higher in the SI-SU (59.4 vs. 44.9%, p < 0.001) but the relationship was no more significant after adjustment (aOR = 1.17; 95% CI: 0.87-1.5). CONCLUSIONS: Our study shows that moving from a stroke team in a monitored setting (ICU) to an organized stroke unit leads to a significant reduction in the 3 months unfavorable outcome in patients with an acute ischemic or hemorrhagic stroke. Cardiovascular monitoring is indispensable, but benefits of a semi-intensive Stroke Unit are driven by additional elements beyond intensive cardiovascular monitoring. This observation supports the ongoing development of Stroke Centers for efficient stroke care.

A Facile and Green Approach for the Preparation of Silver Nanoparticles on Graphene Oxide with Favorable Antibacterial Activity.

Herein, we introduce a simple precipitation method for preparing graphene oxide-silver nanoparticle (GO/AgNP) composites, utilizing Calendula officinalis (C. officinalis) seed extract as both a reducing and stabilizing agent. Our research combines the sustainable preparation of graphene oxide (GO) with the green synthesis of silver nanoparticles (AgNPs), aiming to explore the potential of the obtained composite as a novel antibacterial material. To establish a benchmark, the synthesis was also performed using sodium citrate, a conventional reducing agent. The resultant GO/AgNP composites were characterized through several analytical techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy, X-ray diffraction (XRD), infrared (IR) spectroscopy, and ultraviolet-visible (UV-vis) spectroscopy, confirming the successful functionalization of GO with AgNPs. The antibacterial effectiveness of the composites was systematically assessed against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), with nanoparticle concentrations spanning from 0 to 250 µg/mL, utilizing mostly disk diffusion and colony-forming unit (CFU) count assays. The AgNPs were characterized by a size range of 15-50 nm. Notably, the GO/AgNP composite prepared using C. officinalis seed extract demonstrated superior antibacterial activity at all tested concentrations, outperforming both pure GO and the GO/AgNP composite prepared with sodium citrate. The most pronounced antibacterial effect was observed at a concentration of 32.0 µg/mL. Therefore, this innovative synthesis approach may offer a valuable contribution to the development of new therapeutic agents to combat bacterial infections, suggesting further exploration into antibacterial coatings or potential drug development.

Orthogonality catastrophe and decoherence in a trapped-fermion environment.

The Fermi-edge singularity and the Anderson orthogonality catastrophe describe the universal physics which occurs when a Fermi sea is locally quenched by the sudden switching of a scattering potential, leading to a brutal disturbance of its ground state. We demonstrate that the effect can be seen in the controllable domain of ultracold trapped gases by providing an analytic description of the out-of-equilibrium response to an atomic impurity, both at zero and at finite temperature. Furthermore, we link the transient behavior of the gas to the decoherence of the impurity, and to the degree of the non-Markovian nature of its dynamics.

Determination of 13 estrogenic endocrine disrupting compounds in atmospheric particulate matter by pressurised liquid extraction and liquid chromatography-tandem mass spectrometry.

This paper describes the optimisation of an analytical method for the simultaneous determination of up to 13 estrogenic endocrine disrupting compounds (EDCs), including natural and synthetic estrogens, alkylphenols, bisphenol A and phthalate esters, in atmospheric particulate matter. This methodology is based on pressurised liquid extraction and liquid chromatography-tandem mass spectrometry and is the first method described for analysis of estrogens in air. Samples were collected with high-volume samplers equipped with quartz microfiber filters. Two selected reaction monitoring transitions were chosen for identification and confirmation of the target compounds. Quantitation was performed by the internal standard method with the use of deuterated surrogate standards. The analytical features of the method were satisfactory: absolute recoveries were around 45 % for all compounds, except estrogens (∼29 %), because of matrix effects. Repeatability was in all cases below 15 %. Quantitation limits of the method ranged from 5 pg/m(3) (for diethylphthalate) to 83 pg/m(3) (for 17-α-ethynylestradiol). As a part of the validation procedure, the developed method was applied to the analysis of eight air particulate samples (fine grain-size particles, PM2.5) collected in industrial, urban and non-polluted suburban areas of A Coruña (NW of Spain). Results evidenced the presence of dibutylphthalate, diethylhexylphthalate and nonylphenol in all samples. The highest concentration corresponded to dibutylphthalate (54.7 ng/m(3)) in an industrial area. Daily exposure to these EDCs in terms of estradiol equivalents (3 pg/day for toddlers and 5 pg/day for adults) is not expected to pose a risk to human health.

Performance of infrared ear and forehead thermometers: a comparative study in 205 febrile and afebrile children.

AIMS AND OBJECTIVES: This study compared readings from two professional-grade, commercially available infrared (IR) thermometers, the ThermoScan® PRO 4000 prewarmed tip ear thermometer and the Temporal Scanner(™) TAT-5000 temporal artery thermometer. BACKGROUND: The repeatability and precision of readings from IR thermometers for professional use were questioned in the past, but in recent years, these types of thermometers have been technologically improved, so their ability to replicate standard temperature readings reliably should be re-examined. DESIGN: Febrile and afebrile children were recruited from the emergency department, overflow treatment areas and the paediatric intensive care unit of a large hospital in Argentina. Each child had a randomised sequence of seven temperature readings, including three from the ear, three from the forehead or behind the ear and one reference oral or rectal reading. METHODS: Temperature readings were taken with the ThermoScan PRO 4000, the Temporal Scanner TAT-5000 and the monitor mode of SureTemp® Plus, a widely used professional-grade contact thermometer, for reference. RESULTS: Of 205 children, 46% were febrile, per reference thermometer readings. While mean ThermoScan PRO 4000 febrile measurements did not differ significantly from reference, mean Temporal Scanner TAT-5000 febrile measurements were significantly lower (by a mean of 0·42 °C) than the reference. Overall bias of the ThermoScan PRO 4000 was significantly lower than that of the Temporal Scanner TAT-5000; repeatability was 1·5 times higher, and overall false-negative rate was about a third that of Temporal Scanner TAT-5000, when compared to the reference. CONCLUSIONS: This study indicates that the ThermoScan PRO 4000 provides measurements closer to those of a professional-grade contact thermometer when compared to the Temporal Scanner TAT-5000. RELEVANCE TO CLINICAL PRACTICE: The odds of misclassifying a febrile child as non-febrile were about threefold higher with the Temporal Scanner TAT-5000 temporal artery thermometer than with the ThermoScan® PRO 4000 ear thermometer.

"Downward steps technique" with CO2 ultrapulsed laser for the treatment of rhinophyma: our protocol.

BACKGROUND: The rhinophyma is an important soft-tissue hypertrophy of the nose. In literature a wide range of surgical approaches to rhinophyma has been described such as dermoabrasion, scalpel shave, cryosurgery, electrocautery, near total excision with skin grafting, and laser excision. PATIENTS AND METHODS: The authors describe their experience with CO(2) ultrapulsed laser in 14 elderly male patients, using their personal approach, the Downward steps technique. With this technique they removed the pathological hypertrophic tissue using a progressive reduction of the laser power during the treatment. They obtained good results from morphological and aesthetic point of view, in a single laser session. CONCLUSIONS: Major complications such as hypertrophic scars, infections, hyperpigmentation were not observed.

Treatment of stages IIIIV of the Dupuytrens Disease using a personal approach: percutaneous needle fasciotomy (PNF) and minimal invasive selective aponeurectomy.

The authors present their experience in treating 23 fingers on 20 patients affected by Dupuytrens Disease in stages III and IV of the Tubiana classification with their personal technique that involves the percutaneous needle fasciotomy followed 40 days after by a selective open aponeurectomy on the previously treated cord, by making a small cutaneous incision. The treatment requires careful selection of the patients. In fact, patients suffering from the disease for more than 5 years and all the cases with a suspicion of joint rigidity are excluded from the study. The average follow up period was approximately 48 months. 18 out of the 20 patients had excellent functional recovery. Skin grafts or local flaps are not required after selective aponeurectomy with these surgical steps. The advantages of this technique include its simplicity, minimal discomfort to patients, rapid functional recovery, low recurrence rate and low cost.
