RESUMO
Gastropericardial fistula is a rare, extremely serious and life-threatening condition. Its most common aetiology is secondary to iatrogenic injury following gastric surgery. Clinical manifestations may be non-specific with precordial pain, simulating an acute coronary syndrome, and may be accompanied by electrocardiogram abnormalities. Diagnosis is made by thoracoabdominal computed tomography (CT) with oral and intravenous contrast. Treatment is surgical and consists of repair of the anomalous communication. We present the case of an 81-year-old male patient with gastropericardial fistula who underwent surgery, with the aim of reviewing the diagnosis and the appropriate therapeutic strategy.

Relative to the numerous studies focused on mammalian schistosomes, fewer include avian schistosomatids particularly in the southern hemisphere. This is changing and current research emerging from the Neotropics shows a remarkable diversity of endemic taxa. To contribute to this effort, nine ducks (Spatula cyanoptera, S.versicolor, Netta peposaca), 12 swans (Cygnus melancoryphus) and 1,400 Physa spp. snails from Chile and Argentina were collected for adults and larval schistosomatids, respectively. Isolated schistosomatids were preserved for morphological and molecular analyses (28S and COI genes). Four different schistosomatid taxa were retrieved from birds: Trichobilharzia sp. in N. peposaca and S. cyanoptera that formed a clade; S.cyanoptera and S. versicolor hosted Trichobilharzia querquedulae; Cygnus melancoryphus hosted the nasal schistosomatid, Nasusbilharzia melancorhypha; and one visceral, Schistosomatidae gen. sp., which formed a clade with furcocercariae from Argentina and Chile from previous work. Of the physid snails, only one from Argentina had schistosomatid furcocercariae that based on molecular analyses grouped with T. querquedulae. This study represents the first description of adult schistosomatids from Chile as well as the elucidation of the life cycles of N.melancorhypha and T. querquedulae in Chile and Neotropics, respectively. Without well-preserved adults, the putative new genus Schistosomatidae gen. sp. could not be described, but its life cycle involves Chilina spp. and C. melancoryphus. Scanning electron microscopy of T. querquedulae revealed additional, undescribed morphological traits, highlighting its diagnostic importance. Authors stress the need for additional surveys of avian schistosomatids from the Neotropics to better understand their evolutionary history.

The present study aimed to investigate the spontaneous dynamics of large-scale brain networks underlying mindfulness as a dispositional trait, through resting-state electroencephalography (EEG) microstates analysis. Eighteen participants had attended a standardized mindfulness-based stress reduction training (MBSR), and 18 matched waitlist individuals (CTRL) were recorded at rest while they were passively exposed to auditory stimuli. Participants' mindfulness traits were assessed with the Five Facet Mindfulness Questionnaire (FFMQ). To further explore the relationship between microstate dynamics at rest and mindfulness traits, participants were also asked to rate their experience according to five phenomenal dimensions. After training, MBSR participants showed a highly significant increase in FFMQ score, as well as higher observing and non-reactivity FFMQ sub-scores than CTRL participants. Microstate analysis revealed four classes of microstates (A-D) in global clustering across all subjects. The MBSR group showed lower duration, occurrence and coverage of microstate C than the control group. Moreover, these microstate C parameters were negatively correlated to non-reactivity sub-scores of FFMQ across participants, whereas the microstate A occurrence was negatively correlated to FFMQ total score. Further analysis of participants' self-reports suggested that MBSR participants showed a better sensory-affective integration of auditory interferences. In line with previous studies, our results suggest that temporal dynamics of microstate C underlie specifically the non-reactivity trait of mindfulness. These findings encourage further research into microstates in the evaluation and monitoring of the impact of mindfulness-based interventions on the mental health and well-being of individuals.

OBJECTIVE: To compare quality of life, in patients living with HIV infection with pharmaceutical care according to the CMO methodology: capacity, motivation and opportunity versus conventional follow-up. METHODS: Longitudinal, prospective, multicenter, health intervention study, conducted between October 2019 and November 2021 in 14 centers throughout Spain. Patients over 18 years of age, receiving antiretroviral treatment and attending the consultations of the participating Pharmacy Services for 1 year were included. Patients who did not have the autonomy to complete the planned questionnaires were excluded. At baseline, participating centers were randomized to continue using the same systematics of work (traditional follow-up) or to implement the CMO model using patient stratification models, goal setting in relation to pharmacotherapy, use of motivational interviewing, as well as longitudinal follow-up enabled by new technologies. The main variable was the difference in the number of dimensions positively affected in each follow-up arm at 24 weeks of follow-up according to the MOS-HIV questionnaire. In the CMO group, the interventions performed the most frequently were recorded. RESULTS: 151 patients were included. The median age was 51.35 years. A significant improvement in quality of life was found at the end of follow-up in the CMO group, reducing the number of patients with negatively affected dimensions (2/11 vs 8/11). The most frequent interventions carried out in the CMO group, according to the taxonomy, were Motivation (51,7%) and review and validation (49,4%). CONCLUSIONS: The quality of life of patients is higher in those centers that develop Pharmaceutical Care based on the CMO methodology compared to traditional follow-up.

BACKGROUND AND OBJECTIVE: In orthopedic surgery, it is clear that an optimal standardized closure technique has not yet been developed. Locally, there are no objective data describing the standard surgical practice in wound closure. The aim of this study is to analyze the clinical practice of surgical wound closure in orthopedic surgery by means of a survey of a representative local sample and thus obtain information on the context of closure in Spain. METHOD: an ad hoc group of specialists in orthopedic surgery and traumatology was formed. The group of experts, after analyzing the literature, developed a questionnaire of 32 closed multiple-choice questions divided into the following blocks: hemostasis, surgical wound closure (deep, superficial, and cutaneous), and dressings. RESULTS: A total of 471 surgeons responded to the survey completely and with sufficient information to perform the descriptive analysis. 79% believe that ATX can influence the decrease in surgical site infection rate. 96% believe that the type of deep closure at the level of the arthrotomy could influence outcomes and complications after hip and/or knee replacements. 85% believe that the type of shallow closure at the subcutaneous level may influence outcomes and complications after hip and/or knee replacement. 64% of surgeons use single-use incisional negative pressure therapy for the treatment of surgical wound complications (seroma, prolonged drainage, dehiscence). CONCLUSIONS: There is a high level of variability in wound closure in our setting and a low level of training on the subject. The authors recommend that the different scientific societies invest resources to improve training in this field and reduce the percentage of surgeons who are considered inadequately trained, as well as adapting closure techniques to those considered gold standard according to the evidence.
RESUMO
Insight into the molecular mechanisms governing the development and maintenance of pluripotency is important for understanding early development and the use of stem cells in regenerative medicine. We demonstrate the selective inhibition of mTORC1 signaling is important for developing the inner cell mass (ICM) and the self-renewal of human embryonic stem cells. S6K suppressed the expression and function of pluripotency-related transcription factors (PTFs) OCT4, SOX2, and KLF4 through phosphorylation and ubiquitin proteasome-mediated protein degradation, indicating that S6K inhibition is required for pluripotency. PTFs inhibited mTOR signaling. The phosphorylation of S6 was decreased in PTF-positive cells of the ICM in embryos. Activation of mTORC1 signaling blocked ICM formation and the selective inhibition of S6K by rapamycin increased the ICM size in mouse blastocysts. Thus, selective inhibition of mTORC1 signaling supports the development and maintenance of pluripotency.

RESUMO
The spine is the third most frequent location for metastatic disease, after the lung and liver. On the other hand, the most frequent bone tumours are metastases and the spine is the main location. A review of the different imaging techniques available, both radiological and nuclear medicine, and the morphological appearance of spinal metastases in each of them is performed. Magnetic resonance imaging is the best imaging modality for detection of spinal metastases. It is important to make the differential diagnosis between vertebral fracture of osteoporotic and pathological cause. Spinal cord compression is a serious complication of metastatic disease and its assessment by imaging through objective scales is decisive for estimating spinal stability and therefore establishing treatment. Lastly, percutaneous intervention techniques are briefly discussed.
RESUMO
BACKGROUND: Different types of therapies were proven effective for the medical management of motor and non-motor symptoms in Parkinson's disease (PD). We aimed to gain consensus on the dopamine agonist (DA) therapy use in different clinical scenarios of Parkinson's disease (PD) patients. METHODS: This consensus study was based on the nominal group technique. Initially, a consensus group comprising 12 expert neurologists in the PD field identified the topics to be addressed and elaborated different evidence-based preliminary statements. Next, a panel of 48 Spanish neurologists expressed their opinion on an internet-based systematic voting program. Finally, initial ideas were reviewed and rewritten according to panel contribution and were ranked by the consensus group using a Likert-type scale. The analysis of data was carried out by using a combination of both qualitative and quantitative methods. The consensus was achieved if the statement reached ≥ 3.5 points in the voting process. RESULTS: The consensus group produced 76 real-world recommendations. The topics addressed included 12 statements related to DA therapy in early PD, 20 statements concerning DA treatment strategy in patients with motor complications, 11 statements associated with DA drugs and their side effects, and 33 statements regarding DA therapy in specific clinical scenarios. The consensus group did not reach a consensus on 15 statements. CONCLUSION: The findings from this consensus method represent an exploratory step to help clinicians and patients in the appropriate use of DA in different stages and clinical situations of PD.
RESUMO
Mesocestoides is a controversial tapeworm with significant lack of data related to systematics and life cycles. This helminth has an indirect life cycle with vertebrates, mostly carnivorous mammals, as definitive hosts. Theoretically, a coprophagous arthropod would be the first intermediate host, and herptiles, mammals, and birds, which prey on these insects, would represent the second intermediate hosts. However, recent evidence suggests that this life cycle would require only two hosts, with no arthropods involved. In the Neotropics, although there are records of mammals and reptiles as hosts for Mescocestoides, no molecular analyses have been performed. This work aimed to record an additional intermediate host and molecularly characterize the isolated larvae. Thus, 18 braided tree iguanas (Liolaemus platei) from Northern Chile were collected and dissected during 2019. One lizard was parasitized by three morphotypes of larvae compatible with tetrathyridia of Mescocestoides. To achieve its specific identity, a molecular approach was performed: 18S rRNA and 12S rRNA loci were amplified through cPCR. The inferred phylogenies confirmed the morphological diagnosis and stated that all morphotypes were conspecifics. The sequences for both loci formed a monophyletic clade with high nodal support, representing a sister taxon to Mescocestoides clade C. This study represents the first molecular characterization of any taxon of Mescocestoides from the Neotropics. Future surveys from potential definitive hosts would help to elucidate its life cycle. Furthermore, an integrative taxonomic approach is required in additional studies from the Neotropical region, which would contribute to a better understanding of the evolutionary relationships of this genus.

BACKGROUND: STAT-ON™ is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient at every moment of the day in normal life. Our aim was to analyze the opinion of different Parkinson's disease experts about the STAT-ON™ tool after using the device in a real clinical practice setting (RCPS). METHODS: STAT-ON™ was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. Each neurologist had the device for at least three months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. RESULTS: Two thirds of neurologists (53.8% females; mean age 44.9±9 years old) worked in a Movement Disorders Unit, the average experience in PD was 16±6.9 years, and 40.7% of them had previously used other devices. A total of 119 evaluations were performed in 114 patients (range 2-9 by neurologist; mean 4.5±2.3). STAT-ON™ was considered "quite" to "very useful" by 74% of the neurologists with an overall opinion of 6.9±1.7 (0, worst; 10, best). STAT-ON™ was considered better than diaries by 70.3% of neurologists and a useful tool for the identification of patients with advanced PD by 81.5%. Proper identification of freezing of gait episodes and falls were frequent limitations reported. CONCLUSION: STAT-ON™ could be a useful device for using in PD patients in clinical practice.

In the present work, an aerosol-assisted CVD (AACVD) system is described, together with a representative example of the synthesis of nanostructured coatings, which is an attractive alternative to being implemented at the industrial level. The semi-automated AACVD system synthesizes thin films or coatings of nanostructured materials, mainly metal oxides, and noble metals. Its main components, as well as its operation, are presented here. This simple AACVD method makes it possible to produce the coatings at relatively low temperatures and in a single step. Finally, the synthesis of CuO and Co3O4 nanostructured coatings deposited on stainless steel substrates is reported, which are excellent candidates for use as selective absorbent materials. The CuO and Co3O4 coatings present high quality and purity; no further thermal treatments are required to obtain the pure and crystalline phases. The main highlights of the proposed method are as follows: a)An AACVD System for depositing thin films and coatings designed and entirely fabricated at the Centro de Investigación en Materiales Avanzados, S.C.b)A low temperature (350 °C) synthesis protocol to obtain CuO and Co3O4 nanostructured coatings on stainless steel substrates.c)The CuO and Co3O4 coatings presented the optimum characteristics to be considered selective absorbent materials.
RESUMO
INTRODUCTION: Post-dural puncture headache (PDPH) is the most common complication following lumbar puncture. However, its incidence varies according to the series consulted. Different factors associated with its onset have been identified. OBJECTIVES: The purpose of this study is to determine the incidence of PDPH and to identify predisposing factors for its appearance. METHOD: Prospective, descriptive study in 57 patients who underwent lumbar puncture procedures. To this end, variables associated with patient-related risk factors, clinical and procedural factors with the presence of PDPH were analysed. The incidence of PDPH was 38.6% and factors associated with onset included young age and previous history of headache. RESULTS: The incidence of PDPH was higher in women and presented greater intensity in this group, though studies with a larger sample size would need to be conducted. CONCLUSIONS: We must bear in mind the factors associated with the appearance of PDPH, which include: young age, history of headache, and the perception of procedural difficulty, to better inform patients and optimise the techniques used.

RESUMO
BACKGROUND AND PURPOSE: The carotid stent placement as a therapeutic option for carotid stenosis has been increasing among years; therefore, studies are required to evaluate the security and efficacy of its materials. The purpose of this study was to evaluate the distal filter and the proximal balloon-guided catheter with flow inversion as protection devices during carotid angioplasty and stenting. METHODS: This is a retrospective, observational study of patients diagnosed with carotid stenosis treated with angioplasty between January 1, 2014, and June 30, 2020; we analyzed a radiology service database to compare the distal filter and the proximal balloon-guided catheter as protection devices during angioplasty. RESULTS: One hundred seventy-five angioplasties were performed, the distal filter was the most prevalent embolic protection device used (66%), patients baseline characteristics did not differ between groups with different embolic protection devices, except for history of dyslipidemia (p < 0.000). As well, we did not find any significant differences between the groups in the device related complications, intervention time (p = 0.140), unrelated complications (p = 0.693) and functional independence at 90 days (p = 0.096). CONCLUSIONS: In our study the proximal balloon-guided catheter and the distal filter protection device as protection devices during the carotid stenting didn't show significant differences regarding complications related to the system.

Psychotic disorders typically manifest from late adolescence to early adulthood, and an earlier onset might be associated with greater symptom severity and a worse long-term prognosis. This study aimed to compare the cognitive characteristics of patients with first-episode psychosis (FEP) by their age at onset. We included 298 patients diagnosed with FEP and classified them as having an early onset (EOS), youth onset (YOS), or adult onset (AOS) based on age limits of ≤ 18 years (N = 61), 19-24 years (N = 121), and ≥ 25 years (N = 116), respectively. Socio-demographic and clinical variables included age at baseline, gender, socio-economic status, antipsychotic medication, DSM-IV diagnoses assessed by clinical semi-structured interview, psychotic symptom severity, and age at onset. Neuropsychological assessment included six cognitive domains: premorbid intelligence, working memory, processing speed, verbal memory, sustained attention, and executive functioning. The EOS group had lower scores than the YOS or AOS groups in global cognition, executive functioning, and sustained attention. Although the scores in the YOS group were intermediate to those in the EOS and AOS groups for most cognitive factors, no statistically significant differences were detected between the YOS and AOS groups. Age at onset results in specific patterns of cognitive interference. Of note, impairment appears to be greater with EOS samples than with either YOS or AOS samples. A longitudinal study with a larger sample size is needed to confirm our findings.

Introducción: el consumo de estimulantes de tipo anfetamínico (ETA) y sus derivados está cada vez más presente en los estudiantes universitarios y, en particular, en los programas de medicina. El objetivo principal de este estudio fue revisar la literatura sobre el uso de ETA y sus derivados en estudiantes de medicina latinoamericanos. Materiales y método: se realizó una revisión de la literatura disponible, utilizando las bases de datos PubMed, SciELO y LILACS. Se encontraron un total de 1.054 artículos, de los cuales 17 fueron seleccionados para esta revisión. Resultados: la revisión muestra, en general, una mayor frecuencia de uso de ETA en estudiantes de medicina de América Latina en comparación con la población general y estudiantes de otras carreras universitarias. También existe una tendencia a un mayor uso en hombres, de mayor nivel socioeconómico y en cursos posteriores del programa. La razón más informada para usar ETA fue aumentar el rendimiento académico. Como factor protector se destacaron los deportes, el tiempo en familia y la profesión de alguna creencia religiosa. De los artículos seleccionados, no se encontraron estudios sobre las consecuencias a largo plazo del uso de ETA en estudiantes de medicina. Discusión: en resumen, los estudiantes de medicina latinoamericanos tienen un alto consumo de ETA, por lo que es evidente la necesidad de nuevos estudios para mejorar la precisión estadística, determinar factores de riesgo específicos, estudiar las consecuencias a largo plazo y establecer políticas de prevención y tratamiento.
Introduction: the consumption of amphetamine-type stimulants (ATS) and their derivatives are increasingly present in university students and in particular in medical programs. The main objective of this study was to review the literature on the use of ATS and their derivatives in Latin American medical students. Materials and method: a review of the literature available was performed, using PubMed, SciELO, and LILACS databases. A total of 1054 articles were found, of which 17 were selected for this review. Results: the review generally shows a higher frequency of use of ATS in medical students of Latin America compared to the general population and students from other university degrees. There is also a tendency of a higher use in men, from higher socioeconomic status, and in later courses of the program. The most reported reason for using ATS was to increase the academic performance. As a protective factor, sports, family time and professing some religious belief stood out. Of the selected articles, no studies were found on the long-term consequences of the use of ATS in medical students. Discussion: in summary, Latin American medical students have a high consumption of ATS, and therefore there is an evident need for new studies to improve statistical precision, to determine specific risk factors, to study long-term consequences, and to stablish prevention policies and treatment.

INTRODUCTION: Enhanced Recovery After Surgery (ERAS) protocols and educational programmes have been shown to accelerate orthopaedic surgery recovery with fewer complications, and improve patient-reported outcomes (PROs) for different types of surgery. The objective was to evaluate the impact of an ERAS programme including a patient school on health outcomes and PROs for Total Knee Replacement (TKR) surgery. MATERIAL AND METHODS: A multidisciplinary group created the programme and the patient school (preoperative consultations where the patients' surgical processes are explained and are also given instructions for an appropriate perioperative care management). An observational, prospective study was conducted on all patients operated for TKR from March 2021 to March 2022. Main health outcomes were: hospital stay length, surgical complications and surgery cancellations due to a wrong preoperative medication management. PROs evaluated were: patient satisfaction with pain management, the school, and quality of life before and after surgery (EQ-5D). RESULTS: One hundred thirty-three patients were included. Median hospital stay length was 3 days (IQR 3-5). Rate of surgical complications was 25.6%. No surgery was cancelled. Patient satisfaction rates with pain management and with the school were 8.10/10 and 9.89/10, respectively. Concerning quality of life, mean improvement in mobility and knee pain after the surgery was 0.66 (p < 0.05) and 0.84 (p < 0.05), respectively. CONCLUSIONS: The ERAS programme including a patient school was highly successful with a fast recovery, a short hospital stay length, no surgery cancellations, and improved PROs.
