Of all the known pillared layered clays (PILC), Al-PILC is the most studied. In spite of that, its use on a commercial scale is not yet possible due to the large amount of water required for its synthesis. The aim of the present work was to take advantage of the beneficial effects of ultrasound radiation for reducing intercalation time, and to optimize the synthesis parameters in order to find a viable industrial means of preparing Al-PILC.
A comprehensive study of the effect of ultrasonic radiation on the parameters which have a direct effect on the amount of water used in the synthesis was conducted, specifically on the effects of: (1) mmol of Al/g of clay ratio (R) by decreasing the volume of A1 solution and keeping the amount of clay constant, (2) the concentration of clay in the initial suspension (or not suspending the clay at all), and (3) the concentration of the A1 precursor solution. The use of ultrasonic radiation produced the expected reduction in exchange time which was attributed to a decrease of the clay-particle size. This decrease of particle size gave rise to an improvement in the diffusion of the A1 precursor towards the core of the clay grain leading to solids with increased surface areas, basal spacing and X-ray diffraction peak definition. By optimizing the synthesis parameters directly involved in the consumption of water, it was possible to decrease the amount used by >60%.
Transition between adolescence and adulthood represents the most important challenge for personal development and involves several transformations: physical, psychological and social. It is a complex age bracket, concurring the transition from youth psychiatric units to adult ones, with an increased risk for the appearance of mental disorders and risky behaviours. TRANVIA program, developed in Avilés, provides psychiatric assistance to patients between 15 and 25 years old, diagnosed with a severe psychiatric disorder or with an increased risk of having one.
Objectives
Our objectives are: ensuring clinical continuity assistance, promoting communication among professionals and the empowerment of our patients to improve their functionality and quality of life.
Methods
Descriptive study including patients involved in TRANVIA program from November 2019 to November 2021.
Results
During this two-years period there have been 44 referrals to the program, 11 of them were rejected for failure to comply with diagnostic criteria. In November 2021 there were 33 patients included in the TRANVIA program with an average age of 17 years old (range: 15-22). 70% of them were men and 30% women. All of them had psychiatric assistance from different sources: youth mental health units, neuropediatrics… About 75% of the patients were diagnosed with autistic spectrum disorder and approximately three-quarters of the sample needed pharmacological treatment. Risperidone was the most prescribed drug. We have also developed other assistance alternatives as home-based care, relaxation sessions, social worker interventions and coordination with schools.
Conclusions
TRANVIA program has allowed us to provide continual attention to vulnerable patients that shift from youth psychiatric units to adult ones. Patients that meet inclusion criteria were enrolled independently the type of assistance they have previously received. Accessibility and flexibility were our priority. During the described period there was only one dropout, three patients required psychiatric hospitalization and two others visited the emergency department. There have been no cases of completed suicide.
This new project studies the diversity of socioecological niches across the agropastoral transition in the Andes, utilising a multi-isotope approach to track human territories and allocate subsistence tasks. During the agropastoral period, we discriminate different diachronic niches with varying extents of maize farming and altitudinal mobility.
In this study, we explore how early career advancement affects the gender pay gap among top executives and argue that an employee's age at attainment of an executive position serves as a signal that helps reduce biases toward women, thereby lowering gender pay differentials. We analyze career data of 803 executives from public high-technology manufacturing firms in the United States by collecting information from ExecuComp, Marquis Who's Who, LinkedIn, and Bloomberg. Our results indicate that attaining a top management position at a young age has a positive effect on pay, particularly among women, and this effect is due to the variable portion of compensation, which represents a large proportion of compensation among top executives. Further, recent research has identified a pay premium among high-potential female managers, although its key drivers remain unclear. This paper explores age as an observable signal that influences this premium and reduces the gender pay gap.
Pregnancy has sociocultural implications that lead to conceiving it depending on the cultural context (Noguera & Rodríguez, 2008). Self-care is a cultural practice associated with the well-being of mother and child during pregnancy (Carmona, Hurtado and Marín 2007). Being relative to culture, self-care varies according to current beliefs. Beliefs are the concretion of a way of thinking about the environment that surrounds us (Peirce, 1903).
Objectives
Analyze the beliefs of women from a population group in Montería, about pregnancy and its implications regarding self-care in eating.
Methods
Qualitative approach. Sources: primary. Sample: due to saturation, 15 pregnant women assigned to the Mocarí neighborhood hospital in Montería. Instrument: semi-structured open interview. The information was processed through AtlasTi, implementing content analysis. Emerging categories: contents, routines in food.
Results
Main belief: food affects the well-being of mother and child. It is adequate or inappropriate depending on categories such as content and routines. The former refer to the food consumed, the latter indicate the times of consumption.
Conclusions
Beliefs about pregnancy operate as generators of mental habits, projected wishes and concrete actions. Therefore, they are an important starting point for the implementation of self-care practices at the institutional level.
We explore the economic merits of on-farm water storage with tailwater recovery systems to reduce aquifer depletion in a region with expanding irrigated acreage and substantial off-season precipitation. Gains are substantial on a broad scale and long planning horizon, including more than $4 billion in producer surplus, 5 million acre-feet of conserved groundwater, and land capitalization of $24 per acre. Sensitivity analyses provide insights with respect to the impact of discount rates, rainfed returns, return flows, and aquifer recharge rates. Results can inform stakeholders about the optimal allocation of funds directed at agricultural practice adoption and agricultural water investments.
The coronavirus disease 2019 (COVID-19) pandemic is putting health-care systems under unprecedented stress to accommodate unexpected numbers of patients forcing a quick re-organization. This article describes the staff management experience of a third level referral hospital in the city of Madrid, Spain, one of the cities and hospitals with the largest number of COVID-19 cases.
A newly created COVID-19-specific clinical management unit (CMU) coordinated all clinical departments and conducted real-time assessments of the availability and needs of medical staff, alongside the hospital’s general management board. The CMU was able to (i) redeploy up to 285 physicians every week to bolster medical care in COVID-19 wards and forecast medical staff requirements for the upcoming week so all departments could organize their work while coping with COVID-19 needs, (ii) overview all clinical activities conducted in a medicalized hotel, and (iii) recruit a team of roughly 90 volunteer medical students to accelerate data collection and evidence generation.
The main advantage of a CMU composed by a member of every job category—its ability to generate rapid, locally adapted responses to unexpected challenges—made it perfect for the unprecedented increase in health-care need generated by the COVID-19 pandemic.
We present interferometric continuum and molecular line emission maps obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) of OH231.8+4.2, a well studied bipolar nebula around an asymptotic giant branch (AGB) star that is key to understand the remarkable changes in nebular morphology and kinematics during the short transition from the AGB to the Planetary Nebula (PN) phase. The excellent angular resolution of our maps (∼20 mas ∼30 AU) allows us to scrutinize the central nebular regions of OH231.8+4.2, which hold the clues to understanding how this iconic object assembled its complex nebular architecture. We report, for the first time in this object and others of its kind (i.e. pre-PNe with massive bipolar outflows), the discovery of a rotating circumbinary disk of radius ∼30 AU traced by NaCl, KCl, and H2O emission lines. The disk lies at the base of a young bipolar wind with signs of rotation as well. A compact spatially resolved dust disk is found perpendicular to the bipolar outflow. We also identify a point-like continuum source, which likely represents the central Mira star enshrouded by a ∼3 R* shell or disk of hot (∼1400 K) freshly formed dust. The point source is slightly off-centre from the disk centroid, enabling us for the first time to place constraints to the orbital separation of the central binary system.
Apis mellifera is infected by more than 24 virus species worldwide, mainly positive-sense, single-stranded RNA viruses of the Dicistroviridae and Iflaviridae families. Among the viruses that infect honey bees, Deformed wing virus is the most prevalent and is present as three master variants DWV-A, B, and C. Given that the ectoparasitic mite Varroa destructor vectors these virus variants, recombination events between them are expected, and variants and their recombinants can co-exist in mites and honeybees at the same time. In this study, we detect, through RT-qPCR, the presence of DWV-A and B in the same samples of adult bees from colonies of Argentina. Total RNA was extracted from pools of ten adult bees from 45 apiaries distributed across the main beekeeping Provinces of Argentina (Buenos Aires, Santa Fe, Córdoba, Santiago del Estero, Río Negro, and Mendoza); then RT-qPCR reactions were performed to detect DWV-A and B, with specific primer pairs. After the amplifications, PCR products (204 and 660 bp amplicons for DWV-B, and ~250 bp for DWV-A) were purified and sequenced to verify that they corresponded to reported sequences, analyzing them using the Blast software. Of the 45 samples analyzed by RT-qPCR, over 90% were infected with DWV-A and 47% were also positive for DWV-B, where it was found in high prevalence specifically in colonies of A. mellifera of the Buenos Aires Province. Future studies will determine the impact of this type of the virus and its ability to recombine with the other DWV types in the apiaries of our country.
Benzodiazepines are widely used drugs. However, their chronic use has revealed that they can lead to dependence. The objective of this study is to review the different pharmacological strategies used in the management of benzodiazepine dependence and new trends in pharmacological interventions.
Method
We searched in MEDLINE and in the Cochrane Database System Review, selecting studies from 1980 until the present, in which a pharmacological intervention was made for benzodiazepine detoxification in mono-dependence cases.
Results
There is a consensus about gradual rather than abrupt tapering benzodiazepines in benzodiazepine discontinuation. Other extended traditional strategy has been switching from short half-life to long half-life benzodiazepines before gradual taper. A great variety of agents have been used as adjuvant medication in Benzodiazepine Withdrawal Syndrome (BWS) with varying degrees of success. In the last years research has focus in the use of anticonvulsant drugs. Both carbamzepine and valproate, have demonstrated to be beneficial in benzodiazepine discontinuation. Also, preliminary data suggest that new anticonvulsant agents (gabapentin, pregabalin, oxcarbazepine and topiramate) could be helpful.
Discussion
Although multiple drugs have been investigated for pharmacological management of BWS, only few have demonstrated significant efficacy. Anticonvulsant drugs are one of them. Both, carbamazepine and valproate, have shown benefits in reducing withdrawal severity. The available data currently support the use of new anticonvulsant (gabapentin, pregabalin, oxacarbazepine and topiramate), in the treatment of different drug-dependences such as alcohol, cocaine and opiate dependence. Moreover, there is a growing trend in the literature toward the use of these agents in benzodiazepine mono-dependence.
Alcoholism is a chronic relapsing disorder characterized by compulsive drinking, alcohol seeking, loss of control over alcohol consumption, and impaired social and occupational functioning. Treatment of Alcohol Dependence (AD) comprises two steps, detoxification and relapse prevention (RP). Traditionally, long half-life benzodiazepines have been the most widely used agents for alcohol detoxification. On the other hand, disulfiram, naltrexone and acamprosate are the three drugs that have been approved for relapse prevention. In the last decades, nevertheless, there is a growing interest in the use of anticonvulsant drugs in the management of both, detoxification and relapse prevention of alcohol.
Aims
To review the different pharmacological strategies in which an anticonvulsant was used in the management of AD.
Method
We searched in MEDLINE and in the Cochrane Database System Review, selecting all studies from 1980 until present, in which a pharmacological intervention with anticonvulsant agents was made for alcohol detoxification or RP.
Results
The most tested anticonvulsant drugs are the classical Carbamazepine and Valproate. Both have demonstrated to be efficacious in Alcohol Withdrawal Syndrome and RP. However, the use of these agents has been limited by their hepatic and hematologic toxicity. Novel anticonvulsants such as Gabapentin, Pregabalin, Topiramate, Oxcarbazepine and Zonisamide have also been found to be effective, with the advantage of rapid onset of action, lower toxicity and fewer side effects.
Conclusions
Anticonvulsants are efficacious and safe agents in the management of AD. Further randomized, double-blind, placebo-controlled trials are warranted to increase the evidence of the use of these agents.
The trans-3;4-dichloro-N-(2-(dimethylamine) cyclohexyl) labelled as U-47700 has a high affinity with the selective receptor, considered to have 7.5 times the binding affinity of morphine; as a result, it is sold as a recreational drug because of its analgesic and euphoric effects. Several toxicity cases and some fatalities have been reported during 2016.
Objectives
To describe the presence of trans-3;4-dichloro-N-(2-(dimethylamine) cyclohexyl) in samples delivered to Energy Control during 2016 in Barcelona.
Methods
From January 2016 to October 2016, 4031 samples were delivered and only those samples containing trans-3;4-dichloro-N-(2-(dimethylamine) cyclohexyl) were studied, 6 of them were analysed as U-47700 (0.148%). Samples were analysed by energy control, a Spanish harm-reduction NGO that offers users the possibility of analysing the substances they intend to consume. Analysis was done by gas chromatography–mass spectrometry.
Results
From the 6 samples that were analysed as trans-3;4-dichloro-N-(2-(dimethylamine) cyclohexyl), the presentation of 4 of them was white powder and the rest were not described. The procedence of the samples was Canada (2), USA (1), Sweden (1), Holland (1) and the remaining sample was not described. All samples were received during 2016.
Conclusions
The use of trans-3;4-dichloro-N-(2-(dimethylamine)cyclohexyl) is progressively increasing in Barcelona. Its harmful effects are being reported in recent medical literature and consumption represents an emerging issue, gaining popularity among recreational opioid users. It is potentially lethal when mixed with depressants like alcohol or benzodiazepines and overdose risk is higher compared to other opioids. This drug is not being detected by routine in medical test.

Synthetic cathinones, the active component in “bath salts”, have surfaced as a popular alternative to other illicit drugs of abuse, such as cocaine, MDMA (ecstasy), and methamphetamine, due to their potent psychostimulant and empathogenic effects.
Objectives
To describe the presence of Ethylone in samples delivered to energy control from 2014 to 2015 in Spain.
Methods
The total number of samples analyzed from 2014 to 2015 was 8324. Only those samples containing ethylone were studied. They were analyzed by energy control, a Spanish harm reduction NGO that offers the possibility of analysing the substances that users report. Analysis was done by gas chromatography-mass spectrometry.
Results
From June 2014 to December 2015, 8324 samples were delivered to EC. From this samples 28 (0.336%) contained ethylone. Twelve (0.144%) were delivered as MDMA, representing a 0.783% of the samples delivered as such, and only one sample (0.012%) delivered as MDMA presented ethylene as an adulterant along with MDMA. Other 6 samples (0.072%) were delivered as ethylone and 10 samples (0.120%) were delivered as unknown pills.
Discussion
Ethylone consumption is found to be an emerging issue according to the results of our samples, an increase of such is found during 2015. This might be traduced as an increase of ethylone in the drug market, but a sample selection bias should be considered as samples were voluntary delivered by consumers. An alarming phenomenon is that in some occasions ethylone is sold as MDMA, but effects take longer to occur and last longer, which may lead to an overdose if used as MDMA.

New Psychoactive Substances (NPS) appear to be increasing in popularity because they mimic the effect of traditional drugs. DOB is a world-wide controlled phenethylamine, with agonist activity in 5HT2A receptors. Its effects are comparable to those of LSD, with dosage range 1.0–3.0 mg and duration 18–30 h.
Objective
To assess the presence of DOB in the substances submitted to, and analyzed by, energy control.
Materials and methods
All samples presented to Energy Control (EC) from August 2009 to August 2015 were analyzed. EC is a spanish harm-reduction non governmental organization that offers to users the possibility of analyzing the substances they intend to consume. Samples in which DOB was detected using gas chromatography-mass spectrometry were selected for this study.
Results
From a total of 20,062 samples, 13 contained DOB (0,06%), with no clear variations among the years studied. The samples were mostly sold as DOC(8), DOB(2) and LSD(2). Nine out of total 13 samples presented as blotter.
Conclusion
Results suggest that availability of DOB in the Spanish drug market is anecdotic. Nonetheless, a number of the samples containing DOB were not sold as such, increasing the possibility of side effects, as users may ignore which substance they are actually using. When a patient presents at an Emergency Department with persistent hallucinogenic symptomatology after ingesting a blotter, psychiatrist should be aware of long-lasting psychedelics such as DOB.

New psychoactive substances (NPS) are substances that have recently appeared on the market and are not under international control. NPS use is experiencing an unprecedented increase. DiPT, 4-HO-DiPT and 4-AcO-DiPT are new psychoactive tryptamines and their effects may differ from those of other psychoactive tryptamines.
Objective
To explore the presence of DiPT, 4-HO-DiPT and 4-AcO-DiPT from samples delivered to and analyzed by Spanish harm reduction service Energy Control.
Materials and methods
All samples analyzed from 2009 to 2014 delivered as DiPT, 4-HO-DiPT and 4-AcO-DPT or containing these substances. Analysis was performed by gas chromatography–mass spectrometry.
Results
From 17,432 samples, 4-HO-DiPT was found in 16, delivered as 4-HO-DiPT (6); 4-AcO-DiPT (7); DiPT (1); 4-AcO-DMT (1) and cocaine (1). 4-AcO-DiPT was found in 16, delivered as 4-AcO-DiPT (12); 5-MeO-DMT (1); 5-MeO-DiPT (1); 4-AcO-DMT (1) and cocaine (1). Only 4 samples contained DiPT, all presented as DiPT. Nine samples contained both 4-AcO-DiPT and 4-HO-DiPT. During the years of study, 4-HO-DiPT deliverance was increasing (4 samples in 2014) while deliverance of 4-AcO-DiPT and DiPT was decreasing (1 sample in 2014).
Conclusions
Increasing 4-HO-DiPT presence could translate a progressive replacement of 4-AcO-DiPT and DiPT recreational use. Clinical relevance comes from its growing use and the absence of scientific evidence on humans, therefore relying on users subjective experience to predict the effects.

Previous studies show association between sexual dysfunction and antipsychotic treatment.
Objectives
To study the prevalence and clinical correlates of sexual dysfunction in schizophrenic inpatients treated with antipsychotics. To analyze the influence of sexual complaints in treatment adherence.
Methods
Retrospective descriptive study of psychiatric inpatients diagnosed of schizophrenia following DSM-IV-TR) criteria and treated in an acute care unit of Psychiatry in an university hospital in a 12-month period. Patients treated with combination of antipsychotics (typical and atypical) were excluded from the analysis (n = 60). Sexual side effects were evaluated with Udvalg for Kliniske Undersogelser (UKU) Side Effect Rating Scale and evaluated in two treatment groups: conventional antipsychotics, and atypical antipsychotics. Patients were asked about subjective experience with other treatments.
Results
The mean age of subjects was 32.4 (SD = 8.7). From the whole sample 38 (63.3%) were men and 22 (36.7%) women. Sexual dysfunction related to treatment was present in 78% of patients. Men were more affected than women and 69% of them related that sexual dysfunction had influenced the decision of treatment withdrawal previous to income. Amenorrhea was more common on risperidone and amisulpride. Analysis of different antipsychotics and its relationship with sexual dysfunction are presented.
Conclusions
Sexual dysfunction is a frequent side effect associated with antipsychotics in schizophrenic patients. The sexual side effects may reduce the quality of life and may increase non-compliance that is usually associated to readmissions and worse prognosis of severe mental illness.

Depression is a prevalent illness in elderly people. Cognitive deterioration associated to depressive symptoms is frequently considered as Dementia, especially in primary care. The study of the relation between both pathologies is necessary to correct treatment of mental illness in elderly people.
Aims
The aim of this study is to investigate whether depressive symptoms are related to certain areas of cognitive decline in elderly people.
Methods
The sample included community people older than 65 years (n = 927), mean age 72.9; 55.1% were women and 44,9% men. Instruments used were Beck Depression Inventory (BDI), Blessed Dementia Scale (BDS), Mini Mental State Examination (MMSE), verbal fluency test, clock drawing task, Wechsler digit substitution test and Wechsler similarity test.
Results
Of the sample, 15,2% presented cognitive deterioration in Blessed Dementia Scale, with statistical significance in relation between growing age, female sex and cognitive deterioration (P < 0.005). Twenty-eight percent of the sample present cognitive decline, finding the same relation between sex, age and cognitive condition. Of the sample, 33.5% presented mild depression, 9.1% moderate depression and 1.4% presented severe depression using BDI. Correlations between depression and cognitive tests were analyzed. In demographic factors, social support was significantly correlated with depression but marital status, occupation and education were not correlated.
Conclusions
There is a high prevalence of depressive symptoms and cognitive deterioration in elderly people. High levels of depressive symptoms are associated with cognitive deterioration, especially in comprehension and judgment, delayed recall, verbal memory and visuospacial coordination in elderly people.
