- Abstract
Introduction: The correct storage of specimens in the Pathology service is of vital importance for patient safety. However, there are no clear recommendations as regarding how long samples should be stored for a minimum period., Material and Methods: A working group of the Spanish Society of Anatomic Pathology has reviewed a series of recommendations established in the literature and after two rounds of consultations and a discussion and voting phase has established a series of storage time proposals., Results: Each of the proposals is presented with the data found in the literature and sometimes offers definitions and exceptions to the proposal., Conclusion: These recommendations, which are minimums, establish a period of at least 10 years for paraffin embedded blocks (including cell blocks), histological preparations, general cytology, pathologic cervico-vaginal cytology and electron microscopy blocks; at least 3 years for cervico-vaginal cytology, 5 years for extracted nucleic acids, at least 4 weeks for tissue in formalin and from the time of diagnosis for liquid cytology material and fluids., (Copyright © 2024 Sociedad Española de Anatomía Patológica.

- Abstract
The Laser Megajoule (LMJ) is among the most energetic inertial confinement fusion laser facilities in the world, together with the National Ignition Facility (NIF) in the USA. The construction of the facility began back in 2003, and the first photons were emitted by the laser bundle #28 in 2014. Today, 11 laser bundles consisting of 88 large aperture 0.35×0.35 m
2 laser beams are in operation, delivering daily up to 330 kJ of energy at the wavelength of 351 nm on a target placed in the center of a 10 m diameter vacuum chamber. In this paper, we describe the laser system and its operational performances. We also detail the first laser campaigns carried out to prepare an increase of energy and power on the target. These campaigns, along with the completion of additional bundles mounting, will bring LMJ performance to 1.3 MJ thanks to 22 bundles in operation.- Published

- Abstract
Interest in Metschnikowia ( M. ) pulcherrima is growing in the world of winemaking. M. pulcherrima is used both to protect musts from microbial spoilage and to modulate the aromatic profile of wines. Here, we describe the isolation, characterization, and use of an autochthonous strain of M. pulcherrima in the vinification of Chasselas musts from the 2022 vintage. M. pulcherrima was used in co-fermentation with Saccharomyces cerevisiae at both laboratory and experimental cellar scales. Our results showed that M. pulcherrima does not ferment sugars but has high metabolic activity, as detected by flow cytometry. Furthermore, sensory analysis showed that M. pulcherrima contributed slightly to the aromatic profile when compared to the control vinifications. The overall results suggest that our bioprospecting strategy can guide the selection of microorganisms that can be effectively used in the winemaking process.

- Abstract
Prior research has established that valence-trustworthiness and power-dominance are the two main dimensions of voice evaluation at zero-acquaintance. These impressions shape many of our interactions and high-impact decisions, so it is crucial for many domains to understand this dynamic. Yet, the relationship between acoustical properties of novel voices and personality/attitudinal traits attributions remains poorly understood. The fundamental problem of understanding vocal impressions and relative decision-making is linked to the complex nature of the acoustical properties in voices. In order to disentangle this relationship, this study extends the line of research on the acoustical bases of vocal impressions in two ways. First, by attempting to replicate previous finding on the bi-dimensional nature of first impressions: using personality judgements and establishing a correspondence between acoustics and voice-first-impression (VFI) dimensions relative to sex (Study 1). Second (Study 2), by exploring the non-linear relationships between acoustical parameters and VFI by the means of machine learning models. In accordance with literature, a bi-dimensional projection comprising valence-trustworthiness and power-dominance evaluations is found to explain 80% of the VFI. In study 1, brighter (high center of gravity), smoother (low shimmers), and louder (high minimum intensity) voices reflected trustworthiness, while vocal roughness (harmonic to noise-ratio), energy in the high frequencies (Energy3250), pitch (Quantile 1, Quantile 5) and lower range of pitch values reflected dominance. In study 2, above chance classification of vocal profiles was achieved by both Support Vector Machine (77.78%) and Random-Forest (Out-Of-Bag = 36.14) classifiers, generally confirming that machine learning algorithms could predict first impressions from voices. Hence results support a bi-dimensional structure to VFI, emphasize the usefulness of machine learning techniques in understanding vocal impressions, and shed light on the influence of sex on VFI formation., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
The Petawatt Aquitaine Laser (PETAL) facility was designed and constructed by the French Commissariat à l'énergie atomique et aux énergies alternatives (CEA) as an additional PW beamline to the Laser MegaJoule (LMJ) facility. PETAL energy is limited to 1 kJ at the beginning due to the damage threshold of the final optics. In this paper, we present the commissioning of the PW PETAL beamline. The first kJ shots in the amplifier section with a large spectrum front end, the alignment of the synthetic aperture compression stage and the initial demonstration of the 1.15 PW @ 850 J operations in the compression stage are detailed. Issues encountered relating to damage to optics are also addressed.

- Abstract
Optical vortices are currently one of the most intensively studied topics in optics. These light beams, which carry orbital angular momentum (OAM), have been successfully utilized in the visible and infrared in a wide variety of applications. Moving to shorter wavelengths may open up completely new research directions in the areas of optical physics and material characterization. Here, we report on the generation of extreme-ultraviolet optical vortices with femtosecond duration carrying a controllable amount of OAM. From a basic physics viewpoint, our results help to resolve key questions such as the conservation of angular momentum in highly nonlinear light-matter interactions, and the disentanglement and independent control of the intrinsic and extrinsic components of the photon's angular momentum at short-wavelengths. The methods developed here will allow testing some of the recently proposed concepts such as OAM-induced dichroism, magnetic switching in organic molecules and violation of dipolar selection rules in atoms.

- Abstract
Men and women differ in exposure to trauma and the development of posttraumatic stress disorder (PTSD); however, research regarding sex differences in recovery from PTSD has been sparse. This study evaluated the treatment response trajectory for 69 male and female interpersonal assault survivors, using a modified Cognitive Processing Therapy (CPT) protocol that allowed survivors to receive up to18 sessions of CPT, with treatment end determined by therapy progress. Few sex differences were observed in trauma history, baseline PTSD and depressive severity, Axis I comorbidity, anger, guilt and dissociation. Women did report more sexual assault in adulthood and elevated baseline guilt cognitions, whereas men reported more baseline anger directed inward. Attrition and total number of sessions did not differ by sex. Over the course of treatment and follow-up, men and women demonstrated similar rates of change in PTSD and depressive symptoms. However, medium effect sizes on both of these primary outcomes at the 3-month follow-up assessment favored women. Several differences in the slope of change emerged on secondary outcomes such that women evidenced more rapid gains on global guilt, guilt cognitions, anger/irritability, and dissociation. Results suggest that male survivors may warrant additional attention to address these important clinical correlates., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

- Abstract
Background: The aim of this study was to determine if an intraoperative injection of iodine-125-labeled methylene blue ((125)I-MB) is a sensitive and effective method for detecting SLNs in women with breast cancer., Study Design: Sixty-two women were enrolled in an extended phase II trial using (125)I-MB to guide SLNB. All patients were anesthetized and then injected subcutaneously with 1 mCi (125)I-MB in the outer quadrant of the areola., Results: Radioactivity was detected in the axilla within 3 to 5 minutes. Fifty-eight of 62 (94%) patients had SLNs detected during their procedure. Mean (±SD) number of SLNs per patient was 1.8 ± 1.3 (range 0 to 6). A total of 112 nodes were dissected from 58 women; 110 of these nodes were considered sentinel. One hundred and eight (98%) nodes were hot, 98 (89%) nodes were blue, and 96 (87%) nodes were both hot and blue. Two women had complications; 1 had superficial skin staining and 1 had a superficial skin slough. Both healed uneventfully. No allergic reactions were observed. No radioactive uptake in the thyroid was seen., Conclusions: Iodine-125-labeled methylene blue can be mixed and administered in the operating room, improving hospital efficiency. Patient satisfaction is higher with (125)I-MB than with the technetium 99m sulfur colloid procedure because (125)I-MB does not produce localized burning and other adverse reactions associated with the traditional method, and 125I-MB is administered with the patient under anesthesia. Iodine-125 emits a lower-energy gamma ray than technetium 99m, lowering the surgeon's radiation exposure. Iodine-125-labeled methylene blue SLN identification is safe, cost effective, and produces equivalent outcomes compared with the traditional technique, making it an attractive alternative., (Copyright © 2013 American College of Surgeons.

- Abstract
Recombinant sarafloxacin-recognizing antibody was engineered with the use of novel fluoroquinolone (FQ) derivatives. A monoclonal FQ antibody, 6H7, was targeted to random mutagenesis to broaden the specificity of the antibody in development of a generic assay for FQ antibiotics. Engineering involved the synthesis of different small-sized FQ molecules to immobilize and detect the mutant antibodies. Selections with labeled FQs resulted in several mutant antibodies with increased affinity or wider specificity toward different FQs. The best characterized mutant antibody was capable of recognizing seven of eight targeted FQs below maximum residue limits set by the European Union. The results are promising in regard to the development of a multiresidue immunoassay for FQs based on a single antibody., (Copyright © 2010 Elsevier Inc. All rights reserved.)

McClain AD, Chappuis C, Nguyen-Rodriguez ST, Yaroch AL, and Spruijt-Metz D
- Abstract
Background: Understanding the correlates of dietary intake is necessary in order to effectively promote healthy dietary behavior among children and adolescents. A literature review was conducted on the correlates of the following categories of dietary intake in children and adolescents: Fruit, Juice and Vegetable Consumption, Fat in Diet, Total Energy Intake, Sugar Snacking, Sweetened Beverage Consumption, Dietary Fiber, Other Healthy Dietary Consumption, and Other Less Healthy Dietary Consumption in children and adolescents., Methods: Cross-sectional and prospective studies were identified from PubMed, PsycINFO and PsycArticles by using a combination of search terms. Quantitative research examining determinants of dietary intake among children and adolescents aged 3-18 years were included. The selection and review process yielded information on country, study design, population, instrument used for measuring intake, and quality of research study., Results: Seventy-seven articles were included. Many potential correlates have been studied among children and adolescents. However, for many hypothesized correlates substantial evidence is lacking due to a dearth of research. The correlates best supported by the literature are: perceived modeling, dietary intentions, norms, liking and preferences. Perceived modeling and dietary intentions have the most consistent and positive associations with eating behavior. Norms, liking, and preferences were also consistently and positively related to eating behavior in children and adolescents. Availability, knowledge, outcome expectations, self-efficacy and social support did not show consistent relationships across dietary outcomes., Conclusion: This review examined the correlates of various dietary intake; Fruit, Juice and Vegetable Consumption, Fat in Diet, Total Energy Intake, Sugar Snacking, Sweetened Beverage Consumption, Dietary Fiber, Other Healthy Dietary Consumption, and Other Less Healthy Dietary Consumption in cross-sectional and prospective studies for children and adolescents. The correlates most consistently supported by evidence were perceived modeling, dietary intentions, norms, liking and preferences. More prospective studies on the psychosocial determinants of eating behavior using broader theoretical perspectives should be examined in future research.

- Abstract
Schizophrenia is a complex multifactorial brain disorder with a genetic component. Convergent evidence has implicated oxidative stress and glutathione (GSH) deficits in the pathogenesis of this disease. The aim of the present study was to test whether schizophrenia is associated with a deficit of GSH synthesis. Cultured skin fibroblasts from schizophrenia patients and control subjects were challenged with oxidative stress, and parameters of the rate-limiting enzyme for the GSH synthesis, the glutamate cysteine ligase (GCL), were measured. Stressed cells of patients had a 26% (P = 0.002) decreased GCL activity as compared with controls. This reduction correlated with a 29% (P < 0.001) decreased protein expression of the catalytic GCL subunit (GCLC). Genetic analysis of a trinucleotide repeat (TNR) polymorphism in the GCLC gene showed a significant association with schizophrenia in two independent case-control studies. The most common TNR genotype 7/7 was more frequent in controls [odds ratio (OR) = 0.6, P = 0.003], whereas the rarest TNR genotype 8/8 was three times more frequent in patients (OR = 3.0, P = 0.007). Moreover, subjects with disease-associated genotypes had lower GCLC protein expression (P = 0.017), GCL activity (P = 0.037), and GSH contents (P = 0.004) than subjects with genotypes that were more frequent in controls. Taken together, the study provides genetic and functional evidence that an impaired capacity to synthesize GSH under conditions of oxidative stress is a vulnerability factor for schizophrenia.

- Abstract
Objective: Heart manipulation during OPCAB may cause hemodynamical instability in particular for access to the posterior and lateral walls. The 'no compression' technique involves enucleation of the heart without any compression on the cavities, and stabilization of the target area with a suction device. The impact of this technique on hemodynamics is assessed., Methods: In order to analyze a homogeneous group, 26 consecutive patients with triple grafts, one to each side of the heart in the same sequential order (posterior, lateral and anterior wall successively) were selected. Heart rate (HR), mean pulmonary arterial pressure (PAP, mmHg), pulmonary capillary wedge pressure (PCWP, mmHg), mean arterial pressure (MAP, mmHg), cardiac output index (COI, l/min per m(2)), and central venous saturation (SvO(2),%) were monitored. A coronary shunt was used for all the anastomoses., Results: HR was stable with baseline value of 60+/-10 and the highest value for the anterior wall, 63.6+/-8 (P=0.23). PAP and PCWP exhibited their highest increase, when compared with baseline, for the lateral wall, 23.9+/-4.7 vs. 20.7+/-6.2 (P=0.06), and 17.2+/-4.7 vs. 14.9+/-5.6 (P=0.16), respectively. MAP, COI and SvO(2), exhibited their largest drop, when compared with baseline, for the lateral wall too, 73.1+/-9.1 vs. 77.1+/-7.5 (P=0.12), 1.99+/-0.47 vs. 2.26+/-0.55 (P=0.09), and 70.5+/-8.4 vs. 74.8+/-9.3 (P=0.12), respectively., Conclusions: None of the hemodynamical parameter differed significantly from baseline value for all three territories. While hemodynamics was perfectly maintained during the posterior and anterior walls revascularization, exposure of the lateral wall led to marginal changes only.

Definition and lived-in reality of "autonomy" an "human-dignity" may differ as can be shown by means of a patient's situation: it varies whether patient, relatives, general practitioner or hospital doctor are involved. It is most important to assure these terms not only to be fiction but to become a lived reality.

- Abstract
Objective: To compare serum C-reactive protein levels measured using a highly sensitive immunonephelometry method in patients with rapidly destructive versus slowly progressive hip osteoarthritis., Methods: Ten patients meeting criteria for rapidly destructive hip osteoarthritis were compared to 25 patients with slowly progressive hip osteoarthritis defined as less than 0.20 mm joint space loss over the last year. Serum C-reactive protein was assayed using an immunonephelometry method with a detection threshold of 0.17 mg/L and a coefficient of variation of less than 5%., Results: One patient in each group was excluded because of a C-reactive protein level greater than 15 mg/L. The mean C-reactive protein level in the remaining 33 patients was 3.05 +/- 3.46 mg/L (range, 0.10-14.9 mg/L). Mean C-reactive protein was significantly higher in the rapidly destructive group than in the slowly progressive group (5.61 +/- 4.75 versus 1.94 +/- 1.98 mg/L, P = 0.01), even after adjustment for potential confounding factors., Conclusion: Our data suggest that rapidly destructive hip osteoarthritis may be associated with some degree of inflammation reflected by a small but significant increase in serum C-reactive protein levels.

- Abstract
Protein-energy malnutrition is a frequent, but often overlooked problem in geriatric patients. To prevent malnutrition and its severe complications, a systematic strategy for identifying signs, symptoms and risk factors of malnutrition is required. In this review we present a plan for a multidimensional nutritional workup, including functional nutritional assessment. Special aspects of malnutrition management in geriatric patients are discussed (e.g. dementia, tube-feeding, environmental aspects). Use of available diagnostic and therapeutic measures for preventing malnutrition may lead to improved quality of life in many geriatric patients.

- Abstract
The records of 1,710 patients with adenocarcinoma of the stomach treated at Charity Hospital over a 35-year period were reviewed to note any trends which might help in understanding the decreasing incidence and poor prognosis of the disease. The yearly number of gastric cancer patients has dropped from 234/100,000 in the 1950's to 195/100,000 in the 1960's to 108/100,000 patients in the last decade. The percentage of affected white males is decreasing at a rate equal to the increasing frequency of black female patients, while the ratios for black males and white females remain constant. The median age rose from 61.5 years to 66 years over the study period. The operability rate decreased from 82.4% to 72.8% and the resectability rate was 49%. Subtotal gastrectomy was the most common procedure, but radical subtotal gastrectomy gave the best 5-year survival. There are fewer lesions of the antrum today, but the highest number of 5-year survivors had antral lesions. Long-term survival of patients with lesions of the cardia improved from zero in the first 25 years to 14% in the last decade. For the last 2 decades, patients with stage III and IV lesions comprised one-half of the 5-year survivors. Our overall 5-year survival was 7.9%, but in the last decade it was 8.9%. Our 5-year survival for all patients who underwent a resection was 17.9%, but increased to 24.8% for the last decade. These improvements, in combination with a decrease in incidence, have dropped the overall mortality from gastric cancer.

- Abstract
Plasma lipids and apolipoproteins, and hepatic LDL receptor and HMG-CoA reductase activities in biopsy samples were measured in high- and low-responding rhesus monkeys maintained on a cholesterol-rich and regular diets. The effect of a 30-day cholestyramine treatment on the above parameters under both dietary conditions was also determined. On the cholesterol-rich diet the high-responders, when compared to the low-responders, had several-fold increased plasma cholesterol and apoB concentrations and significantly lower HDL apoA-I and cholesterol concentrations. Hepatic LDL receptor and HMG-CoA reductase activities were not detectable in the high-responders, while the low-responders expressed a reduced number of LDL receptors of normal affinity. Administration of cholestyramine resulted in a rapid induction of the hepatic LDL receptors in the high-responders and a small additional increase in the low-responders. Cholestyramine treatment also stimulated the expression of the hepatic HMG-CoA reductase in both groups of monkeys. These changes were accompanied by a dramatic drop in plasma cholesterol and apoB concentrations in the high-responders and, to a lesser extent, in the low-responders. Plasma HDL concentrations in the high-responders rose to levels higher than those seen in the low-responders. The affinity and receptor number were similar in both groups of monkeys on the control diet, but the low-responders had significantly higher HMG-CoA reductase activities. Administration of cholestyramine during the control diet had a small but significant additional effect on the hepatic LDL receptors of the low-responders but not of the high-responders.(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
Of 219 elderly patients admitted consecutively to a geriatric hospital in Switzerland, 59.4% were edentulous. A high proportion of the dentate patients exhibited tooth loss patterns requiring free-end partial dentures in the maxilla (36.0%) or the mandible (69.7%). Of the remaining teeth, 29.3% were decayed, and 45.1% had severe periodontitis. Virtually all (97.8%) dentate and 31.5% of the edentulous subjects were judged to need some kind of dental treatment. In contrast, the subjective need for dental treatment was low in dentate (30.4%) and edentulous (13.1%) subjects. Prosthesis hygiene was poor in 73.8% of the 191 denture wearers whether they needed assistance with oral hygiene or not. The objectively-assessed need for a new prosthesis in edentulous patients was determined by income, marital status, and patient mobility, whereas the need for a prosthesis alteration was related to cognitive function. These findings should help to plan future dental prophylactic and therapeutic services in geriatric hospitals.

- Abstract
An example of a way to establish contact between hospital and outpatient care was demonstrated by the method of working at a clinic for geriatrics and rehabilitation. The basis for evaluation of the working method concerning the patient is optimal information about his situation at the time of hospitalisation. An objective for the hospitalisation can be determined together with the patient. The progress achieved during hospitalisation is judged at regular intervals by the patient and the staff taking care of him. This makes an estimation of the length of required hospitalisation possible. About 40% of the patients returning to family practitioner care require outpatient care. The division between the different services involved is demonstrated. The working method was judged, based on an inquiry at the family practitioners.

- Abstract
The urine of human coffee drinkers who ingested 12 g of instant coffee per day, during 4 days in a first experiment or 12 g within 2 h in a second experiment, was fractionated by XAD-2 column chromatography. The non-polar urine fractions so obtained were not mutagenic in the Ames Salmonella tester strains TA98 or TA100 in either experiment, either with or without beta-glucuronidase treatment of the urine. The non-polar urine fraction of smokers, who smoked 20--30 cigarettes per day during 4 days in the first experiment or 7--18 cigarettes during 7 h in the second experiment, was mutagenic when metabolically activated.

- Abstract
Recently it has been shown that there is a high prevalence of treatable dental conditions in elderly subjects in Switzerland. The purpose of the present prospective study was to assess the value of an oral screening examination intended to help the primary care physician to determine which patients should be referred to a dental service for specialized treatment. Of 219 patients aged over 65 referred consecutively to a geriatric hospital, 58.4% were objectively in need of dental treatment according to the data obtained by a dentist. In a multiple logistic analysis, 4 oral screening criteria (presence of residual teeth of the patient's own, no prosthetic replacement of an edentulous arch, subjective dental treatment requirement, subjective chewing impairment) were found to predict the objectively assessed dental need with a sensitivity of 93.0% and a specificity of 82.4%. Among the patients with objective dental treatment requirement not predicted by the screening examination, 3 had ulcerations of the oral mucosa. An intraoral soft-tissue examination should therefore be included in the screening examination. In conclusion, simple oral screening may serve to identify patients needing dental care with a high degree of diagnostic accuracy. This enables the primary care physicians to screen for oral and dental problems and to refer patients in the same way as for other special treatment problems.

- Abstract
To plan a dental care program for geriatric patients, the dental treatment needs of 219 elderly patients consecutively admitted to a geriatric hospital were quantitatively assessed. Of 89 patients with residual teeth, 97.8% were assessed as needing dental treatment of a mean projected duration of about 312 min per patient. Of the 130 edentulous patients, 30.8% needed dental treatment of a mean projected duration of about 194 min per patient. Patients exhibiting high (greater than 60 min) dental treatment needs were more frequently impaired in activities of daily living than patients with low (less than or equal to 60 min) dental treatment needs (e.g. impaired transfer function 60.2% vs. 28.0%). There was no difference in the oral hygiene or in the cleanliness of removable dentures between patients needing and not needing help in activities of daily living. In conclusion, the present results show a high amount of dental treatment needed in elderly patients. For the planning of an effective dental care program, special attention has to be paid to the interdisciplinary treatment of patients with limitations in activities of daily living. Furthermore, the improvement of the oral hygiene status is of paramount importance in most elderly patients.
