The gambling habits of university students in Aragon, Spain: a cross-sectional study
Gambling has become a routine form of entertainment for many young people. The aim of this study was to describe the gambling behavior that university students are developing in Aragon, Spain, and to analyze whether these habits are more common among students of sports science, on the assumption that they are more likely to have a higher exposure to betting company marketing. A cross-sectional design was applied, with data collected on advertising exposure, gambling habits and experiences, and opinions on the impact of gambling and its regulation from 516 undergraduate students from the University of Zaragoza. The online survey included ad hoc questions and the “Pathological Gambling Short Questionnaire” to screen for potential gambling disorders. Almost half of the sample had bet money at least once in their life (48.1%), and 2.4% screened positive for consideration of a possible diagnosis of pathological gambling. Betting shops (44.2%) were the most common gambling option, and students of sports science showed a higher prevalence of pathological gambling and had greater tendencies to make bets. Gambling is perceived as a normal leisure activity by a significant part of university students. The development of transversal strategies is required to raise awareness towards the potential dangers of gambling. © 2022 by the authors. Licensee MDPI, Basel, Switzerland
Leiomiomas cutáneos: revisión clinicopatológica y epidemiológica
Fundamento. Los leiomiomas cutáneos, superficiales o suprafasciales, se dividen en tres variantes: piloleiomiomas
(PL), angioleiomiomas (AL) y leiomiomas genitales (LG) que
incluyen las formas vulvares, escrotales y areolares. El objetivo fue establecer las características clinicohistológicas y
la incidencia de cada variante, y las posibles asociaciones
con neoplasias internas.
Material y métodos. Se revisaron 255 casos de leiomiomas
cutáneos diagnosticados entre 1982 y 2018 en los servicios
de Anatomía Patológica de tres centros hospitalarios (Navarra y Alicante). Se describieron y compararon variables demográficas, clínicas, histológicas e inmunohistoquímicas.
Resultados. La incidencia en Navarra de PL fue 4,3 casos
por año y millón de habitantes, de AL 20 y de LG 1,4. Las
formas cutáneas suponen aproximadamente el 3,5 % del
total de leiomiomas. La población con PL sufrió más frecuentemente cáncer de mama (OR= 4,8; IC95%: 1,3-17,4;
p= 0,006). Los leiomiomas areolares son de pequeño tamaño, acompañados de dolor local, predominantemente
fasciculares o sólidos, con muy rara afectación del tejido
celular subcutáneo y escasa atipia. Esto contrasta con el
resto de LG, de tamaño medio y rara vez dolorosos, predominantemente nodulares, con frecuente afectación del
tejido celular subcutáneo y atipia.
Conclusiones. Se aporta información sobre las características clinicohistológicas de las distintas variantes de leiomiomas, según las cuales debería replantearse la clasificación de los leiomiomas areolares fuera del grupo de LG. Se
detectó una asociación entre PL y carcinoma de mama que
deberá confirmarse en futuros estudios para determinar si
este leiomioma constituye un marcador de riesgo de cáncer
de mama en mujeres.Background. Cutaneous, superficial and or suprafascial leiomyoma are divided into three variants: piloleiomyomas (PL),
angioleiomyomas (AL) and genital leiomyomas (GL) that include the vulvar, scrotal and areolar forms. This study set
out to establish the clinical and histological characteristics
and incidence of each variant, and any likely associations
with internal neoplasms.
Methods. A review was carried out of 255 cases of cutaneous leiomyomas diagnosed between 1982 and 2018 at the
Pathology departments of three hospitals (Navarra and Alicante). Demographic, clinical, histological and immunohistochemical variables were described and compared.
Results. The incidence of PL in Navarra was 4.3 cases per
million inhabitants a year, with another 20 cases of AL and
1.4 cases of GL. Cutaneous forms make up approximately
3.5% of the total leiomyomas. The population with PL suffered more frequently from breast cancer (OR= 4.8; CI 95%:
1.3-17.4; p= 0.006). Nipple leiomyomas are small, accompanied by localised pain, and are predominantly fascicular
or solid, with very infrequent effect on the subcutaneous
cellular tissue and scarce atypia. This makes for a contrast
with the other GLs, which are medium sized and infrequently painful, predominantly nodular, and frequent effect on the
subcutaneous tissue and atypia.
Conclusions. The information provided here about the clinical and histological characteristics of the different varieties
of leiomyomas indicate that there is a need to reconsider
the classification of nipple leiomyomas outside the group of
GLs. An association between PL and breast carcinoma was
detected, which needs to be confirmed in future studies so
as to determine if this leiomyoma is a risk marker for breast
cancer
European Registry on Helicobacter pylori management (Hp-EuReg): Patterns and trends in first-line empirical eradication prescription and outcomes of 5 years and 21 533 patients
Objective
The best approach for Helicobacter pylori management remains unclear. An audit process is essential to ensure clinical practice is aligned with best standards of care.
Design
International multicentre prospective non-interventional registry starting in 2013 aimed to evaluate the decisions and outcomes in H. pylori management by European gastroenterologists. Patients were registered in an e-CRF by AEG-REDCap. Variables included demographics, previous eradication attempts, prescribed treatment, adverse events and outcomes. Data monitoring was performed to ensure data quality. Time-trend and geographical analyses were performed.
Results
30 394 patients from 27 European countries were evaluated and 21 533 (78%) first-line empirical H. pylori treatments were included for analysis. Pretreatment resistance rates were 23% to clarithromycin, 32% to metronidazole and 13% to both. Triple therapy with amoxicillin and clarithromycin was most commonly prescribed (39%), achieving 81.5% modified intention-to-treat eradication rate. Over 90% eradication was obtained only with 10-day bismuth quadruple or 14-day concomitant treatments. Longer treatment duration, higher acid inhibition and compliance were associated with higher eradication rates. Time-trend analysis showed a region-dependent shift in prescriptions including abandoning triple therapies, using higher acid-inhibition and longer treatments, which was associated with an overall effectiveness increase (84%-90%).
Conclusion
Management of H. pylori infection by European gastroenterologists is heterogeneous, suboptimal and discrepant with current recommendations. Only quadruple therapies lasting at least 10 days are able to achieve over 90% eradication rates. European recommendations are being slowly and heterogeneously incorporated into routine clinical practice, which was associated with a corresponding increase in effectiveness
European registry on helicobacter pylori management: Effectiveness of first and second-line treatment in Spain
The management of Helicobacter pylori infection has to rely on previous local effectiveness due to the geographical variability of antibiotic resistance. The aim of this study was to evaluate the effectiveness of first and second-line H. pylori treatment in Spain, where the empirical prescription is recommended. A multicentre prospective non-interventional registry of the clinical practice of European gastroenterologists concerning H. pylori infection (Hp-EuReg) was developed, including patients from 2013 until June 2019. Effectiveness was evaluated descriptively and through a multivariate analysis concerning age, gender, presence of ulcer, proton-pump in-hibitor (PPI) dose, therapy duration and compliance. Overall, 53 Spanish hospitals were included, and 10, 267 patients received a first-line therapy. The best results were obtained with the 10-day bismuth single-capsule therapy (95% cure rate by intention-to-treat) and with both the 14-day bismuth-clarithromycin quadruple (PPI-bismuth-clarithromycin-amoxicillin, 91%) and the 14-day non-bismuth quadruple concomitant (PPI-clarithromycin-amoxicillin-metronidazole, 92%) therapies. Second-line therapies were prescribed to 2448 patients, with most-effective therapies being the triple quinolone (PPI-amoxicillin-levofloxacin/moxifloxacin) and the bismuth-levofloxacin quadruple schemes (PPI-bismuth-levofloxacin-amoxicillin) prescribed for 14 days (92%, 89% and 90% effective-ness, respectively), and the bismuth single-capsule (10 days, 88.5%). Compliance, longer duration and higher acid inhibition were associated with higher effectiveness. “Optimized” H. pylori therapies achieve over 90% success in Spain
Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)
Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters.
Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs).
Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001).
Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio
Early mobilisation in critically ill COVID-19 patients: a subanalysis of the ESICM-initiated UNITE-COVID observational study
Background
Early mobilisation (EM) is an intervention that may improve the outcome of critically ill patients. There is limited data on EM in COVID-19 patients and its use during the first pandemic wave.
Methods
This is a pre-planned subanalysis of the ESICM UNITE-COVID, an international multicenter observational study involving critically ill COVID-19 patients in the ICU between February 15th and May 15th, 2020. We analysed variables associated with the initiation of EM (within 72 h of ICU admission) and explored the impact of EM on mortality, ICU and hospital length of stay, as well as discharge location. Statistical analyses were done using (generalised) linear mixed-effect models and ANOVAs.
Results
Mobilisation data from 4190 patients from 280 ICUs in 45 countries were analysed. 1114 (26.6%) of these patients received mobilisation within 72 h after ICU admission; 3076 (73.4%) did not. In our analysis of factors associated with EM, mechanical ventilation at admission (OR 0.29; 95% CI 0.25, 0.35; p = 0.001), higher age (OR 0.99; 95% CI 0.98, 1.00; p ≤ 0.001), pre-existing asthma (OR 0.84; 95% CI 0.73, 0.98; p = 0.028), and pre-existing kidney disease (OR 0.84; 95% CI 0.71, 0.99; p = 0.036) were negatively associated with the initiation of EM. EM was associated with a higher chance of being discharged home (OR 1.31; 95% CI 1.08, 1.58; p = 0.007) but was not associated with length of stay in ICU (adj. difference 0.91 days; 95% CI − 0.47, 1.37, p = 0.34) and hospital (adj. difference 1.4 days; 95% CI − 0.62, 2.35, p = 0.24) or mortality (OR 0.88; 95% CI 0.7, 1.09, p = 0.24) when adjusted for covariates.
Conclusions
Our findings demonstrate that a quarter of COVID-19 patients received EM. There was no association found between EM in COVID-19 patients' ICU and hospital length of stay or mortality. However, EM in COVID-19 patients was associated with increased odds of being discharged home rather than to a care facility.

Acetylcholinesterase-positive and paraformaldehyde-induced-fluorescence-positive innervation in the upper eyelid of the sheep (Ovis aries)
This is the first study which describes the innervation of some eyelid structures, such as the glands of Moll and the glands of Zeiss. It is also the first to investigate the innervation pattern of the eyelid as a whole. We have studied the acetylcholinesterase-positive and paraformaldehyde-induced-fluorescence-positive (FIF+) innervation pattern of the different structures that constitute the upper eyelid of the sheep. There is widespread acetylcholinesterase-positive innervation in the epithelium, but not such an abundant FIF+ innervation. Both types of innervation are represented in the connective tissue by trunks or fibers that are distributed towards the different structures immersed within them. In the glands of Zeiss, cholinesterasepositive innervation is much more widespread than FIF innervation. On the contrary, the glands of Moll present denser FIF+ innervation than acetylcholinesterasepositive innervation. The Meibomian glands and the lachrymal glands show a rich acetylcholinesterasepositive and FIF+ innervation. Eyelid muscle innervation is mainly acetylcholinesterase-positive. In the conjunctive membrane there is no acetylcholinesterase-positive innervation, and only scarce FIF+ fibers can be demonstrated
Characterization by immunocytochemistry of ionic channels in Helix aspersa suboesophageal brain ganglia neurons
The aim of this work was to characterize
several ionic channels in nervous cells of the
suboesophageal visceral, left and right parietal, and left
and right pleural brain ganglia complex of the snail
Helix aspersa by immunocytochemistry. We have
studied the immunostaining reaction for a wide panel of
eleven polyclonal antibodies raised against mammal
antigens as follows: voltage-gated-Na+ channel; voltagegated-
delayed-rectifier-K+ channel; SK2-smallconductance-
Ca2+-dependent-K+ channel apamin
sensitive; SK3 potassium channel; charybdotoxinsensitive
voltage-dependent potassium channel; BKCamaxi-
conductance-Ca2+-dependent-K+ channel;
hyperpolarization-activated cyclic nucleotide-gated
potassium channel 4; G-protein-activated inwardly
rectifying potassium channel GIRK2 and voltage-gatedcalcium
of L, N and P/Q type channels. Our results show
positive reaction in neurons, but neither in glia cells nor
in processes in the Helix suboesophageal ganglia. Our
results suggest the occurrence of molecules in Helix
neurons sharing antigenic determinants with mammal
ionic channels. The reaction density and distribution of
immunoreactive staining within neurons is specific for
each one of the antisera tested. The studies of colocalization
of immunoreaction, on alternate serial
sections of the anterior right parietal ganglion, have
shown for several recognized mapped neurons that they
can simultaneously be expressed among two and seven
different ionic protein channels. These results are considered a key structural support for the interpretation
of Helix aspersa neuron electrophysiological activity
Localization of connexins in neurons and glia cells of the Helix aspersa suboesophageal brain ganglia by immunocytochemistry
The aim of the present study was to examine
the distribution of cells expressing connexin 26 (Cx26)
in the suboesophageal visceral, left and right parietal and
left and right pleural ganglia of the snail Helix aspersa
by immunocytochemistry. Altogether we have found
approximately 452 immunoreactive neurons which
represent the 4.7% of the total neurons counted. The
stained large neurons (measured diameter 55-140 μm)
occurred mostly on the peripheral surface of the ganglia
while the small immunostained cells (5-25 μm diameter)
were observed in groups near the neuropil. The number
of large neurons giving positive Cx26-like
immunostaining was small in comparison with that for
medium (30-50 μm diameter) and small sized cells. The
expression of Cx26 was also observed in the processes
of glia cells localized among neurons somata and in the
neuropil showing that the antiserum recognized epitopes
in both protoplasmic and fibrous glia cells of Helix
aspersa. The neuropils of all ganglia showed fibers
densely immunostained. While we have observed a good
specificity for Cx26-antiserum in neurons, a lack of
reaction for Cx43 antiserum was observed in neurons
and glia cells. The reaction for enolase antiserum in
neurons was light and non-specific and a lack of reaction
in glia cells and processes for GFAP antiserum was
observed. Although the percentage of positive neurons
for Cx26 antiserum was low is suggested that in normal
physiological conditions or under stimulation the results can be considered of interest in the interpretation
of Helix aspersa elemental two neuron networks synchronizing activity, observed under applied
extremely low frequency magnetic fields
