Abstract
OBJECTIVE The objective of this study was to describe the outcomes of outpatient oncological neurosurgery (OON) in a European clinical setting and to compare them with the conventional inpatient protocol. METHODS Patients who had undergone OON (either tumor removal or biopsy) at the authors' center since 2019 were analyzed. A matched cohort of patients was selected from patients undergoing tumor surgery in the same period. Collected data included patient demographics, postoperative progress, specific location of the target lesion, and the procedure performed. RESULTS There were 18 patients in the case group and 59 patients in the control group. The outpatient surgeries had a same-day discharge rate of 89%, and all ambulatory patients successfully completed the Enhanced Recovery After Surgery program within 6.24 hours of the procedure. All ambulatory patients underwent Hospital-at-Home postoperative follow-up for an average of 4.12 days. Radiological complications were present in 11% of the case group and 8% of the control group. Postoperative neurological deficit occurred in 6% of the same-day discharge group and 3% of the control group. Among the patients in the control group, 3% suffered from postoperative seizures, whereas no seizures were observed in the case group. These differences were not statistically significant. General anesthesia-related complications were not observed in any of the patients. CONCLUSIONS The authors' findings demonstrate that Enhanced Recovery After Surgery protocols and same-day discharge craniotomy for tumor resection and image-guided biopsy under general anesthesia, when patients are carefully selected, can be safely performed with excellent outcomes in a European clinical setting. The OON program proved to be a viable alternative to conventional hospitalization, showing comparable safety records and offering advantages in terms of patient recovery.

Abstract
BACKGROUND The rapid spread of the SARS-CoV-2 virus during the early phase of the pandemic led to an unprecedented global health crisis. Various factors have influenced self-medication practices among the general population and unsubstantiated prescribing practices among healthcare professionals. OBJECTIVE This study aimed to describe trends in the purchase and sale of medicines during the COVID-19 pandemic period (2020-2022) in Ecuador, by comparing them with pre-pandemic periods. METHODS In this study, a cross-sectional design was employed to conduct a comprehensive analysis of 28 pharmacological groups, categorized according to the Anatomical Therapeutic Chemical Classification (ATC). Utilizing an integrated drug consumption database, the study examined physician prescribing data, medicine usage, and spending levels in Ecuador during the COVID-19 pandemic. The analysis involved computing absolute differences in monthly resolution, calculating excessive expenditure in comparison to previous yearly averages, and using Defined Daily Dose (DDD) methodology for internationally comparable results. Furthermore, a correlation analysis was performed to investigate potential associations between prescribed and consumed medicines and the number of new cases and deaths. RESULTS In Ecuador, the average yearly expenditure among these groups prior to the pandemic (2017-2019) amounted to $150,646,206 USD, whereas during 2020 and 2021, the same groups represented a total expenditure of $228,327,210, reflecting a significant increase. The excess expenditure during this period reached 51.4%, equivalent to $77,681,004 USD. Notably, 13% of this expenditure consisted of Over the Counter (OTC) Medicines. The study also identified a remarkable surge in sales of ivermectin, which increased by 2,057%, and hydroxychloroquine, which increased by 171%, as measured by DDD. CONCLUSIONS This study highlights the substantial consumption of medicines by the population in Ecuador during the pandemic. It is concerning that many medications were sold without proven therapeutic indications, indicating that misinformation and desperation may have led to improper prescribing by physicians and patients resorting to ineffective drugs. Moreover, since the sale of these therapeutic drugs requires a prescription, poor regulation, and a lack of control within pharmacies likely contributed to such practices.

Abstract
Squeezing of the quadratures of the electromagnetic field has been extensively studied in optics and microwaves. However, previous works focused on the generation of squeezed states in a low impedance (Z_{0}≈50 Ω) environment. We report here on the demonstration of the squeezing of bosonic edge magnetoplasmon modes in a quantum Hall conductor whose characteristic impedance is set by the quantum of resistance (R_{K}≈25 kΩ), offering the possibility of an enhanced coupling to low-dimensional quantum conductors. By applying a combination of dc and ac drives to a quantum point contact, we demonstrate squeezing and observe a noise reduction 18% below the vacuum fluctuations. This level of squeezing can be improved by using more complex conductors, such as ac driven quantum dots or mesoscopic capacitors.

Abstract
OBJECTIVE
Despite growing evidence on the benefits of outpatient oncological neurosurgery (OON), it is only performed in a few specialized centers and there are no previous descriptions of established OON programs in Europe. Moreover, increasing application of telemedicine strategies, especially after the start of the coronavirus disease 2019 (COVID-19) pandemic, is drastically changing neurosurgical management, particularly in the case of vulnerable populations such as neuro-oncological patients. In this context, the authors implemented an OON program in their hospital with telematic follow-up. Herein, they describe the protocol and qualitatively analyze the barriers and facilitators of the development process.
METHODS
An OON program was developed through the following steps: assessment of hospital needs, specific OON training, multidisciplinary team organization, and OON protocol design. In addition, the implementation phase included training sessions, a pilot study, and continuous improvement sessions. Finally, barriers and facilitators of the protocol’s implementation were identified from the feedback of all participants.
RESULTS
An OON protocol was successfully designed and implemented for resection or biopsy of supratentorial lesions up to 3 cm in diameter. The protocol included the patient’s admission to the day surgery unit, noninvasive anesthetic monitoring, same-day discharge, and admission to the hospital-at-home (HaH) unit for telematic and on-site postoperative care. After a pilot study including 10 procedures in 9 patients, the main barriers identified were healthcare provider resistance to change, lack of experience in outpatient neurosurgery, patient reluctance, and limitations in the recruitment of patients. Key facilitators of the process were the patient education program, the multidisciplinary team approach, and the HaH-based telematic postoperative care.
CONCLUSIONS
Initiating an OON program with telematic follow-up in a European clinical setting is feasible. Nevertheless, it poses several barriers that can be overcome by identifying and maximizing key facilitators of the process. Among them, patient education, a multidisciplinary team approach, and HaH-based postoperative care were crucial to the success of the program. Future studies should investigate the cost-effectiveness of telemedicine to assess potential cost savings, from reduced travel and wait times, and the impact on patient satisfaction.

Abstract
Abstract
Sub-Saharan African migrants (SAMs) have been disproportionately affected by infectious diseases such as HIV, other sexually transmitted infections (STIs) and Tuberculosis infection (TB). Research on infectious diseases and related factors among migrant populations is critical to further understand these populations' health needs and inform prevention strategies. However, migrants are often underrepresented in national statistics and research. This study aimed to examine correlates of HIV, past STI and past TB among SAMs.
A venue-based sample of 790 SSAMs completed a cross-sectional biobehavioral survey on sexual practices, HIV testing and self-reported infectious diseases; an HIV rapid test was offered. Uni- and multivariable logistic regression analyses were performed to examine factors associated with HIV, past STI and past TB.
Overall, 5.4% of participants were HIV-positive and 16.7% reported a past STI. Odds of being HIV positive increased by age (OR 1.07, 95%CI 1.03-1.11) and were higher among those who experienced violence from a partner (OR 2.77, 95%CI 1.08-7.10). Increased odds of having a past STI were found among migrants with low income (OR 2.86, 95%CI 1.48-5.56), long-term migrants (>25 years residing in Portugal: OR 2.16, 95%CI 1.06-4.38) and those who reported sexual risk behaviors (≥3 sexual partners: OR 2.06, 95%CI 1.14-3.70; inconsistent condom use: OR 2.61, 95%CI 1.32-5.17). In total, 4.1% of participants had TB in the past; these were more likely male (OR 3.42, 95%CI 1.29-9.06) and HIV positive (OR 11.48, 95%CI 4.55-28.94). Half of the participants had never been tested for HIV before, including over a third of those who had STI or TB in the past.
Efforts are needed to reduce missed opportunities for HIV/STIs prevention and uptake of HIV testing among SSAMs through more integrated care, while addressing social determinants of infectious diseases.
Key messages
High levels of HIV, STI and TB infection among SAMs were found to be strongly associated with socioeconomic disadvantage and poor living conditions in the host country. Social inequalities are persistently a major factor affecting risk for HIV, STIs and TB, and thus addressing social determinants of infectious diseases must remain a public health priority.

Abstract
Mapping accurately vegetation surfaces in space and time in the ice-free areas of Antarctica can provide important information to quantitatively describe the evolution of their ecosystems. Spaceborne remote sensing is the adequate way to map and evaluate multitemporal changes on the Antarctic vegetation at large but its nature of occurrence, in relatively small and sparse patches, makes the identification very challenging. The inclusion of an intermediate scale of observation between ground and satellite scales, provided by Unmanned Aerial Vehicles (UAV) imagery, is of great help not only for their effective classification, but also for discriminating their main communities (lichens and mosses). Thus, this paper quantifies accurately recent changes of the vegetated areas in Fildes Peninsula (King George Island, Antarctica) through a novel methodology based on the integration of multiplatform data (satellite and UAV). It consists of multiscale imagery (spatial resolution of 2 m and 2 cm) from the same period to create a robust classifier that, after intensive calibration, is adequately used in other dates, where field reference data is scarce or not available at all. The methodology is developed and tested with UAV and satellite data from 2017 showing overall accuracies of 96% and kappa equal to 0.94 with a SVM classifier. These high performances allow the extrapolation to a pair of previous dates, 2006 and 2013, when atmospherically clear very high-resolution satellite imagery are available. The classification allows verifying a loss of the total area of vegetation of 4.5% during the 11-year time period under analysis, which corresponds to a 10.3% reduction for Usnea sp. and 9.8% for moss formations. Nevertheless, the breakdown analysis by time period shows a distinct behaviour for each vegetation type which are evaluated and discussed, namely for Usnea sp. whose decline is likely to be related to changing snow conditions.

Abstract
Throughout history, many scientists have wondered about the reason for neural pathway decussation in the CNS resulting in contralateral forebrain organization. Hitherto, one of the most accepted theories is the one described by the renowned Spanish physician, Santiago Rámon y Cajal at the end of the 19th century. This Nobel Prize winner, among his many contributions to science, gave us the answer to this question: the key lies in the optic chiasm. Based on the fact that the ocular lenses invert the image formed in the retina, Cajal explained how the decussation of the fibers in the optic chiasm is necessary to obtain a continuous image of the outside in the brain. The crossing of the tactile and motor pathways occurred posteriorly as a compensatory mechanism to allow the cortical integration of the sensory, motor, and visual functions. This theory had a great influence on the scientific community of his time, and maintains its importance today, in which none of the theories formulated to date has managed to entirely refute Cajal's. In addition, the decussation of neural pathways plays a significant role in different diseases, especially in the recovery process after a hemispheric lesion and in several congenital pathologies. The advantages of cerebral lateralization have also recently been published, although the evolutionary connection between fiber decussation and cortical function lateralization remains a mystery to be solved. A better understanding of the molecular and genetic substrates of the midline crossing processes might result in significant clinical advances in brain plasticity and repair.

Abstract
Quantum phase transitions (QPTs) are ubiquitous in strongly correlated materials. However, the microscopic complexity of these systems impedes the quantitative understanding of QPTs. We observed and thoroughly analyzed the rich strongly correlated physics in two profoundly dissimilar regimes of quantum criticality. With a circuit implementing a quantum simulator for the three-channel Kondo model, we reveal the universal scalings toward different low-temperature fixed points and along the multiple crossovers from quantum criticality. An unanticipated violation of the maximum conductance for ballistic free electrons is uncovered. The present charge pseudospin implementation of a Kondo impurity opens access to a broad variety of strongly correlated phenomena.

Abstract
The main objective of this paper is to verify the accuracy of delineating and characterizing ice-wedge polygonal networks with features exclusively extracted from remotely sensed images of very high resolution. This kind of mapping plays a key role for quantifying ice-wedge degradation in warming permafrost. The evaluation of mapping a network is performed in this study with two sets of aerial images that are compared to ground reference data determined by fieldwork on the same network, located in Adventdalen, Svalbard (78°N). One aerial dataset is obtained from a photogrammetric survey with RGB+NIR imagery of 20cm/pixel, the other from an UAV (Unmanned Aerial Vehicle) survey that acquired RGB images of 6cm/pixel of spatial resolution. Besides evaluating the degree of matching between the delineations, the morphometric and topological features computed for the differently mapped versions of the network are also confronted, to have a more solid basis of comparison. The results obtained are similar enough to admit that remotely sensed images of very high resolution are an adequate support to provide extensive characterizations and classifications of this kind of patterned ground.

Abstract
OBJECTIVE To assess the quality of life in glaucoma patients and normal subjects, and to assess its relationship with the severity of damage in each eye. METHODS A cross-sectional study was conducted with prospective selection of cases. The study included 464 subjects and were distributed into 4categories. Subjects included in group 1 had both eyes normal, that is with a normal intraocular pressure (IOP), optic disk and visual fields (VF), or mild glaucoma, defined as untreated IOP>21mmHg and abnormal VF with mean defect (MD) over -6dB. Group 2 consisted of patients with both eyes with mild or moderate glaucoma, defined as untreated IOP>21mmHg and abnormal VF with MD between -6 and -12dB. Group 3 included patients with moderate to severe glaucoma, that is, untreated IOP>21mmHg and abnormal VF with MD of less than -12dB in both eyes. Group 4 consisted of patients with asymmetric glaucoma damage, that is, they had one eye with severe glaucoma and the other eye normal or with mild glaucoma. All subjects completed 3 different questionnaires. Global quality of life was evaluated with EuroQol-5D (EQ-5D). Vision related quality of life was assessed with Visual Function Questionnaire (VFQ-25). Quality of life related to ocular surface disease was measured with Ocular Surface Disease Index (OSDI). RESULTS VFQ-25 showed that group 3 had significantly lower scores than group 1 in mental health (P=.006), dependence (P=.006), colour vision (P=.002), and peripheral vision (P=.002). EQ-5D showed no significant differences between any group, but a trend was found to greater difficulty in group 3 than in groups 1 and 2, and in all dimensions. OSDI showed a higher score, or which was the same as a major disability, in groups 2 and 3 than group 1 (P=.021 and P=.014, respectively). VFQ-25 only found significant differences between group 1 and group 4. Dimensions with significant differences were found between group 1 and 3 (both eyes with advanced or moderate glaucoma). These were not found between group 1 and group 4 (the group in which one eye has only mild glaucoma or no glaucoma). This finding confirms that the eye with less glaucoma damage determines the quality of life. CONCLUSIONS Our results demonstrate that quality of life is impaired in patients with glaucoma, and this alteration is greater the more advanced is glaucoma damage in the best or both eyes.

Abstract
Treatment for latent tuberculous infection (LTBI) is a key strategy for the elimination of tuberculosis. Rare adverse reactions associated with LTBI treatment have been reported. We report the only case of acute kidney injury reported to Centers for Disease Control and Prevention surveillance for LTBI treatment-related adverse events. The patient experienced rapid intravascular hemolysis, resulting in heme pigment nephropathy; he was hospitalized and received three hemodialysis treatments, but recovered without sequelae. While LTBI treatment-related adverse events are rare, health care providers should maintain clinical vigilance and regularly counsel patients to facilitate prompt diagnoses and effective clinical management of affected patients.

Abstract
Neutral Lipid Storage Disease with Myopathy (NLSDM) is a rare defect of triacylglycerol metabolism, characterized by the abnormal storage of neutral lipid in organelles known as lipid droplets (LDs). The main clinical features are progressive myopathy and cardiomyopathy. The onset of NLSDM is caused by autosomal recessive mutations in the PNPLA2 gene, which encodes adipose triglyceride lipase (ATGL). Despite its name, this enzyme is present in a wide variety of cell types and catalyzes the first step in triacylglycerol lipolysis and the release of fatty acids. Here, we report the derivation of NLSDM-induced pluripotent stem cells (NLSDM-iPSCs) from fibroblasts of two patients carrying different PNPLA2 mutations. The first patient was homozygous for the c.541delAC, while the second was homozygous for the c.662G>C mutation in the PNPLA2 gene. We verified that the two types of NLSDM-iPSCs possessed properties of embryonic-like stem cells and could differentiate into the three germ layers in vitro. Immunofluorescence analysis revealed that iPSCs had an abnormal accumulation of triglycerides in LDs, the hallmark of NLSDM. Furthermore, NLSDM-iPSCs were deficient in long chain fatty acid lipolysis, when subjected to a pulse chase experiment with oleic acid. Collectively, these results demonstrate that NLSDM-iPSCs are a promising in vitro model to investigate disease mechanisms and screen drug compounds for NLSDM, a rare disease with few therapeutic options.

Abstract
PURPOSE Over the last few years, disordered eating in athletes has received increasing attention. According to several studies, athletes could be more vulnerable to disordered eating and some characteristics specific to the athletic community could be in favour of an increased risk of poor body image and disturbed eating habits in athletes. However, the literature is sparse and some methodological issues in studies have been pointed out. In this context, we aimed at determining the prevalence of disordered eating in French high-level athletes using clinical interviews of three different clinicians and identifying what are the factors associated with disordered eating in athletes. METHODS In France, all athletes registered on the French high-level list have to undergo a yearly evaluation. Data collected during the somatic assessment, the dietary consultation, and the psychological of the yearly evaluation were used. Multivariate analysis was performed for identification of factors associated with disordered eating. RESULTS Out of the 340 athletes included, 32.9% have been detected with a disordered eating. They were difficult to detect by clinicians, as usual criteria did not seem to be reliable for athletes. Competing in sports emphasizing leanness or low body weight was associated with disordered eating; however, gender was not. CONCLUSION These results highlight the need for the development of specific screening tools for high-level athletes. Furthermore, the identification of factors associated with disordered eating could improve early detection and prevention program effectiveness.

Abstract
OBJECTIVES Perioperative epidural analgesia in liver resection provides optimal dynamic pain relief. Coagulation disorders occurring in the postoperative period can lead to greater risk of complications during epidural catheter removal. The aim of this study is to evaluate the effectiveness and complications of epidural analgesia and delayed epidural catheter removal due to postoperative coagulopathy. METHODS A retrospective study of 114 patients undergoing open liver resection and epidural analgesia, from March 2012 to February 2015. Postoperative course of pain intensity, coagulation parameters and delayed catheter removal was analyzed RESULTS: Of the 114 operated patients, 73 met the inclusion criteria. 59% of patients received major hepatectomy (resection ≥ 3 segments) and 15% had Child's Class A cirrhosis (11/73). 96% of catheters functioned properly. 89% of patients had controlled pain (numerical rate scale <3) at rest and 8.2% (6 patients) had severe pain (numerical rate scale > 6) with movement. The INR peaked on postoperative day 2, 1.41 [0.99-2.30], and gradually returned to normal values in most patients by postoperative day 4, 1.26 [0.90 - 2.20]. The catheters were left in place 3.6 (± 1.1) days. In 6 patients (8%), catheter removal was postponed due to coagulation disorders. CONCLUSIONS Epidural analgesia for liver resection was a safe practice, which produced optimal control of postoperative pain. The percentage of delayed catheter removal due to postoperative coagulopathy was low, not requiring transfusion of blood products.

Abstract
The ice-free areas of Maritime Antarctica show complex mosaics of surface covers, with wide patches of diverse bare soils and rock, together with various vegetation communities dominated by lichens and mosses. The microscale variability is difficult to characterize and quantify, but is essential for ground-truthing and for defining classifiers for large areas using, for example high resolution satellite imagery, or even ultra-high resolution unmanned aerial vehicle (UAV) imagery. The main objective of this paper is to verify the ability and robustness of an automated approach to discriminate the variety of surface types in digital photographs acquired at ground level in ice-free regions of Maritime Antarctica. The proposed method is based on an object-based classification procedure built in two main steps: first, on the automated delineation of homogeneous regions (the objects) of the images through the watershed transform with adequate filtering to avoid an over-segmentation, and second, on labelling each identified object with a supervised decision classifier trained with samples of representative objects of ice-free surface types (bare rock, bare soil, moss and lichen formations). The method is evaluated with images acquired in summer campaigns in Fildes and Barton peninsulas (King George Island, South Shetlands). The best performances for the datasets of the two peninsulas are achieved with a SVM classifier with overall accuracies of about 92% and kappa values around 0.89. The excellent performances allow validating the adequacy of the approach for obtaining accurate surface reference data at the complete pixel scale (sub-metric) of current very high resolution (VHR) satellite images, instead of a common single point sampling.

Abstract
OBJECTIVE To evaluate morphological parameters of optic disc and retinal nerve fiber layer (RNFL) examined with confocal laser tomography (HRT3) and laser polarimetry (GDx-VCC) in a normal population, and analyze correlations of these parameters with demographic variables. PATIENTS AND METHODS Cross-sectional study in the context of a glaucoma screening campaign in the primary care center of Barcelona. The individuals selected were non-hypertensive Mediterranean Caucasians with risk for glaucoma development (individuals≥60 years old or≥40 years old with family history of glaucoma or intraocular pressure or myopia>3diopter). All subjects underwent a complete ophthalmic examination, confocal laser tomography (HRT3) and scanning laser polarimetry (GDX-VCC), subjects with results within normal limits only being included. Structural parameters were analyzed along with age, refraction, and pachymetry based on the Spearman rank correlation test. RESULTS A total of 224 subjects included, with a mean age of 63.4±11.1 years. Disc areas, excavation and ring area were 2.14±0.52mm(2), 0.44±0.34mm (2) and 1.69±0.38mm(2), respectively. The mean RNFL (GDX) was 55.9±6.9μm. Age was correlated with lower ring volume, highest rate of cup shape measure, largest mean and maximum cup depth, lower nerve fiber index (NFI) and RNFL (all p-values below .05). CONCLUSION The mean values and distribution of several parameters of the papilla and the RNFL in normal Mediterranean Caucasians population are presented. A loss of thickness of the RNFL, ring thinning, and enlarged cup was observed with increased age.

Abstract
The influence of anesthetic technique on postoperative outcomes has opened a wide field of research in recent years. High-risk patients undergoing non-cardiac surgery are those who have higher incidence of postoperative complications and mortality. A proper definition of this group of patients should focus maximal efforts and resources to improve the results. In view of the significant reduction in postoperative mortality and morbidity in last 20 years, perioperative research should take into account new indicators to investigate the role of anesthetic techniques on postoperative outcomes. Studies focused on the evaluation of intermediate outcomes would probably discriminate better effectiveness differences between anesthetic techniques. We review some of the major controversies arising in the literature about the impact of anesthetic techniques on postoperative outcomes. We have grouped the impact of these techniques into 9 major investigation areas: mortality, cardiovascular complications, respiratory complications, postoperative cognitive dysfunction, chronic postoperative pain, cancer recurrence, postoperative nausea/vomiting, surgical outcomes and resources utilization. In this first part of the review, we discuss the basis on postoperative outcomes research, mortality, cardiovascular and respiratory complications.

Abstract
The knowledge of the influence of anesthetic techniques in postoperative outcomes has opened a large field of research in recent years. In this second part, we review some of the major controversies arising from the literature on the impact of anesthetic techniques on postoperative outcomes in 6 areas: postoperative cognitive dysfunction, chronic postoperative pain, cancer recurrence, postoperative nausea/vomiting, surgical outcomes, and resources utilization. The development of protective and preventive anesthetic strategies against short and long-term postoperative complications will probably occupy an important role in our daily anesthetic practice. Dynamic postoperative pain control has been confirmed as one of the basic requirements of accelerated postoperative recovery programs ("fast-track surgery"), and it is also a preventive factor for development of chronic postoperative pain. The weight of anesthetic technique on postoperative immunosuppression is to be defined. The potential influence of anesthesia on cancer recurrence, is a highly controversial area of research. The classic pattern of perioperative fluid therapy may increase postoperative complications. On the other hand, the maintenance of normoglycemia and normothermia was associated with a decreased postoperative morbidity. The high volume of surgical procedures means that the adequacy of human, organizational and technological resources have a major impact on overall costs.

Abstract
We demonstrate a hybrid architecture consisting of a quantum dot circuit coupled to a single mode of the electromagnetic field. We use single wall carbon nanotube based circuits inserted in superconducting microwave cavities. By probing the nanotube dot using a dispersive readout in the Coulomb blockade and the Kondo regime, we determine an electron-photon coupling strength which should enable circuit QED experiments with more complex quantum dot circuits.

Abstract
OBJECTIVE To describe management of acute postoperative pain on the surgical ward. To study the relationship between pain and a variety of surgical procedures and approaches. To determine the level of information patients received, their expectations, and their satisfaction with treatment of postoperative pain. PATIENTS AND METHODS Cross-sectional observational study by survey and review of patient records. We studied 234 patients, including all who were hospitalized for more than 24 hours after scheduled or emergency operations. The main variables recorded were pain intensity at rest and during movement, including on the day after surgery, and the surgical procedure and approach. RESULTS The prevalence of pain (>3 on a numerical scale) on the surgical ward was 33% at rest and 66% during movement. The prevalence of intense pain (>6 on the numerical scale) was 1.7% at rest and 7.3% during movement. Factors related to greater pain intensity were timing, that is, the first day after surgery, when 74.4% of patients experienced their most intense pain; type of surgery and approach (P<.004); and expecting to experience moderate or intense pain (P<.001). CONCLUSIONS Recording the prevalence of postoperative pain on a surgical ward provides information about the real situation of acute postoperative pain control. Pain on movement is a principal indicator for detecting groups of patients for whom analgesic protocols could be improved. Type of surgery and approach is a fundamental factor to consider when comparing the results of analgesic protocols.

Abstract
The current intraspecific nomenclature in Trypanosoma cruzi describes two major lineages, named T. cruzi I and T. cruzi II, and five sublineages within T. cruzi II, named IIa, IIb, IIc, IId and IIe. The polymorphism of minicircle hypervariable regions (mHVRs) of T. cruzi has been used in many studies for the molecular characterization of parasite populations directly from biological samples. However, the molecular bases that allow strain typing by these markers are still unclear. In this work we examined forty cloned mHVRs sequences of CL-Brener reference strain (IIe sublineage), and we found a predominant group of sequences, with 40% of frequency in this strain, with a 97% of identity among them. Out of the forty clones analyzed, we identified other less representative types, and a few unique ones. This predominant sequence is also present in different reference strains belonging to the other main T. cruzi lineages and sublineages (TcI, IIa, IIb, IIc and IId) although in a many thousand times lower frequency than in the CL-Brener strain, as shown by semiquantitative PCR. Similarly, predominant mHVR sequences previously described for TcIId strains, were clearly more frequent (many thousand times higher) in the IId reference strain analyzed by us (Mncl2) than within the reference strains belonging to the other lineages and sublineages. The analysis of the cloned sequences shows that more sequences than just the major one contribute to define the global pattern of mHVRs RFLP in the CL-Brener strain. The possible usefulness of these predominant sequences for typing TcIId and TcIIe sublineages by semiquantitative PCR, as well as the possible role of these sequences in genotype identification by mHVR probes are discussed.

Abstract
A new method for the assessment of the atrial fibrillatory wave (AFW) from the ECG is presented. This methodology is suitable for signals registered from Holter systems, where the reduced number of leads is insufficient to exploit the spatial information of the ECG. The temporal dependence of the bio-electrical activity were exploited using principal component analysis. The main features of ventricular and atrial activity were extracted, and several basis signals for each subspace were determined. Hence, the estimated (AFW) are reconstructed exclusively from the basis signals that formed the atrial subspace. Its main advantage with respect to adaptive template subtraction techniques was its robustness to variations in the QRST morphology, which thus minimised QRST residua. The proposed approach was first validated using a database of simulated recordings with known atrial activity content. The estimated AFW was compared with the original AFW, obtaining correlation indices of 0.774 +/- 0.106. The suitability of this methodology for real recordings was also proven, though its application to a set of paroxysmal AF ECGs. In all cases, it was possible to detect the main frequency peak, which was between 4.6 Hz and 6.9 Hz for the patients under study.

Abstract
Thrombocytopenia is a potential complication of heparin therapy. There are two forms of heparin-induced thrombocytopenia (HIT). Type-I HIT is characterized by a mild decrease in platelet count that occurs within the first 2-4 days after heparin initiation. The platelet count often returns to normal without stop heparin treatment. The mechanism of thrombocytopenia appears to be due to a direct effect of heparin on platelet activation. The second form (type-II) is an immune-mediated disorder characterized by severe thrombocytopenia, which may include both arterial and venous thrombosis. We present a case of type-II HIT occurred in a hemodialysis patient resulting in acute pulmonary embolism and peripheral venous thrombosis, and review the literature.

The four-body problem for an interacting two-species Fermi gas is solved analytically in a confined quasi-one-dimensional geometry, where the two-body atom-atom scattering length a(aa) displays a confinement-induced resonance. We compute the dimer-dimer scattering length a(dd) and show that this quantity completely determines the many-body solution of the associated BEC-BCS crossover phenomenon in terms of bosonic dimers.

Abstract
INTRODUCTION Atrial fibrillation is the most common arrhythmia on clinical practice and an important risk factor for ictus. The aim of this study was to know the prevalence of this arrythmia in a central district of Madrid. MATERIAL AND METHODS A retrospective study was done analysing medical records of 13,945 patients belonging to a primary care centre of Madrid. Time of study: recruitment of data from September 2000 to May 2001; analysis of data: from September 2001 to May 2002. RESULTS We obtained a total of 425 atrial fibrillations, 348 non-valvular and 77 valvular. Global prevalence of atrial fibrillation in patients over 40 years in our area was 2.52%. (2.47% male, 2.55% female). Risk factors for atrial fibrillation more frequently found in non-valvular were high blood pressure (HBP), diabetes, ischaemic heart disease and left ventricular dysfunction. Among valvulars we found HBP, left atrial size over 45 mm and left ventricular dysfunction. CONCLUSIONS Atrial fibrillation shows a prevalence and distribution in the studied area similar to that found in other European countries.

Abstract
We solve the three-body problem of a quasi-one-dimensional ultracold Fermi gas with parabolic confinement length a (perpendicular) and 3D scattering length a. On the two-body level, there is a Feshbach-type resonance at a (perpendicular)/a approximately 1.46, and a dimer state for arbitrary a (perpendicular)/a. The three-body problem is shown to be universal, and described by the atom-dimer scattering length a(ad) and a range parameter b(ad). In the dimer limit a (perpendicular)/a>>1, we find a repulsive zero-range atom-dimer interaction. For a (perpendicular)/a<<-1, however, the potential has long range, with a(ad)>0 and b(ad)>>a(ad). There is no trimer state, and despite a(ad)=0 at a( perpendicular)/a approximately 2.6, there is no resonance enhancement of the interaction.

Abstract
AIMS/HYPOTHESIS Cyclin-dependent kinase 4 (Cdk4) is crucial for beta cell development. A mutation in the gene encoding for Cdk4, Cdk4R24C, causes this kinase to be insensitive to INK4 cell cycle inhibitors and induces beta cell hyperplasia in Cdk4R24C knockin mice. We aimed to determine whether this Cdk4R24C mutation also affects proper islet function, and whether it promotes proliferation in human islets lentivirally transduced with Cdk4R24C cDNA. METHODS Our study was conducted on wild-type and Cdk4R24C knockin mice. Pancreases were morphometrically analysed. Intraperitoneal glucose tolerance tests and intravenous insulin tolerance tests were performed on wild-type and Cdk4R24C mice. We also did in vitro islet perifusion studies and islet metabolic labelling analysis. Human islets were transduced with Cdk4R24C cDNA. RESULTS Pancreatic islets from Cdk4R24C knockin mice exhibit a larger insulin-producing beta cell area and a higher insulin content than islets from wild-type littermates. Insulin secretion in response to glucose is faster and reaches a higher peak in Cdk4R24C mice without leading to hypoglycaemia. Conversion of pro-insulin into insulin and its intermediates is similar in Cdk4R24C and wild-type mice. Glucose utilisation and oxidation measured per islet were similar in both experimental groups. Insulin secretion was faster and enhanced in Cdk4R24C islets perifused with 16.7 mmol/l glucose, with slower decay kinetics when glucose returned to 2.8 mmol/l. Moreover, human islets expressing Cdk4R24C cDNA exhibited higher beta cell proliferation. CONCLUSIONS/INTERPRETATION Despite their hyperplastic growth, Cdk4R24C insulin-producing islet cells behave like differentiated beta cells with regard to insulin production, insulin secretion in response to glucose, and islet glucose metabolism. Therefore Cdk4 could possibly be used to engineer a source of beta cell mass for islet transplantation.

Abstract
BACKGROUND House dust mite allergens have been shown to be a very important stimulus in the causation of asthma and triggers for the exacerbation of symptoms. Therefore, characterization of mite-derived allergens at the molecular level is an important step for the development of effective diagnostic and therapeutic approaches, as well as for epidemiological studies. OBJECTIVE To clone, express and characterize at the molecular level the cysteine protease from Blomia tropicalis (Bt). METHODS A full-length cDNA encoding Blo t 1 was cloned from a Bt cDNA library using a PCR and RACE-based strategy. The cDNA was PCR-amplified, sequenced and subcloned into a prokaryotic expression vector. The allergenicity of the recombinant Blo t 1 was evaluated for IgE reactivity by Western blot. RESULTS Blo t 1 cDNA encodes a 221 amino acids polypeptide with an estimated molecular weight of 25 kDa. The recombinant protein is 35% identical to other mite cysteine proteases. Recombinant Blo t 1 (rBlo t 1) bound IgE from 62% of Bt skin test-positive serum. Dermatophagoides pteronyssinus (Dp) skin test-positive sera did not react with rBlo t 1, indicating the possible presence of unique IgE epitopes on the rBlo t 1 molecule. A three-dimensional image of Blo t 1, constructed based on predicted analysis, showed conserved secondary and tertiary structure with other cysteine proteases. CONCLUSION We report the cloning, expression and IgE reactivity of Blo t 1, a novel allergen from the domestic mite Blomia tropicalis (Bt), highly homologous to cysteine proteases. This putative cysteine protease, designated Blo t 1, may play a major role as an immunodominant allergen involved in dust mite-specific IgE-mediated hypersensitivity.
