High Energy Density Lithium-Sulfur Batteries Based on Carbonaceous Two-Dimensional Additive Cathodes.

The increasing demand for electrical energy storage makes it essential to explore alternative battery chemistries that overcome the energy-density limitations of the current state-of-the-art lithium-ion batteries. In this scenario, lithium-sulfur batteries (LSBs) stand out due to the low cost, high theoretical capacity, and sustainability of sulfur. However, this battery technology presents several intrinsic limitations that need to be addressed in order to definitively achieve its commercialization. Herein, we report the fruitfulness of three different formulations using well-selected functional carbonaceous additives for sulfur cathode development, an in-house synthesized graphene-based porous carbon (ResFArGO), and a mixture of commercially available conductive carbons (CAs), as a facile and scalable strategy for the development of high-performing LSBs. The additives clearly improve the electrochemical properties of the sulfur electrodes due to an electronic conductivity enhancement, leading to an outstanding C-rate response with a remarkable capacity of 2 mA h cm-2 at 1C and superb capacities of 4.3, 4.0, and 3.6 mA h cm-2 at C/10 for ResFArGO10, ResFArGO5, and CAs, respectively. Moreover, in the case of ResFArGO, the presence of oxygen functional groups enables the development of compact high sulfur loading cathodes (>4 mgS cm-2) with a great ability to trap the soluble lithium polysulfides. Notably, the scalability of our system was further demonstrated by the assembly of prototype pouch cells delivering excellent capacities of 90 mA h (ResFArGO10 cell) and 70 mA h (ResFArGO5 and CAs cell) at C/10.

Dehydrofluorination Process of Poly(vinylidene difluoride) PVdF-Based Gel Polymer Electrolytes and Its Effect on Lithium-Sulfur Batteries.

Gel polymer electrolytes (GPEs) are emerging as suitable candidates for high-performing lithium-sulfur batteries (LSBs) due to their excellent performance and improved safety. Within them, poly(vinylidene difluoride) (PVdF) and its derivatives have been widely used as polymer hosts due to their ideal mechanical and electrochemical properties. However, their poor stability with lithium metal (Li0) anode has been identified as their main drawback. Here, the stability of two PVdF-based GPEs with Li0 and their application in LSBs is studied. PVdF-based GPEs undergo a dehydrofluorination process upon contact with the Li0. This process results in the formation of a LiF-rich solid electrolyte interphase that provides high stability during galvanostatic cycling. Nevertheless, despite their outstanding initial discharge, both GPEs show an unsuitable battery performance characterized by a capacity drop, ascribed to the loss of the lithium polysulfides and their interaction with the dehydrofluorinated polymer host. Through the introduction of an intriguing lithium salt (lithium nitrate) in the electrolyte, a significant improvement is achieved delivering higher capacity retention. Apart from providing a detailed study of the hitherto poorly characterized interaction process between PVdF-based GPEs and the Li0, this study demonstrates the need for an anode protection process to use this type of electrolytes in LSBs.

Interaction between gut microbiota and sex hormones and their relation to sexual dimorphism in metabolic diseases.

Metabolic diseases, such as obesity, metabolic syndrome (MetS) and type 2 diabetes (T2D), are now a widespread pandemic in the developed world. These pathologies show sex differences in their development and prevalence, and sex steroids, mainly estrogen and testosterone, are thought to play a prominent role in this sexual dimorphism. The influence of sex hormones on these pathologies is not only reflected in differences between men and women, but also between women themselves, depending on the hormonal changes associated with the menopause. The observed sex differences in gut microbiota composition have led to multiple studies highlighting the interaction between steroid hormones and the gut microbiota and its influence on metabolic diseases, ultimately pointing to a new therapy for these diseases based on the manipulation of the gut microbiota. This review aims to shed light on the role of sexual hormones in sex differences in the development and prevalence of metabolic diseases, focusing on obesity, MetS and T2D. We focus also the interaction between sex hormones and the gut microbiota, and in particular the role of microbiota in aspects such as gut barrier integrity, inflammatory status, and the gut-brain axis, given the relevance of these factors in the development of metabolic diseases.

Outpatient Submaxillectomy Using Active Drains. Safety of the Procedure and Patient Satisfaction.

Surgical interventions on an outpatient basis are defined as those procedures in which the patient is discharged the same day of the surgery after monitoring the subject during the immediate postoperative period. Submaxillectomies have conventionally been performed on an inpatient basis, and hospital stay was determined by the drain removal. This study aims to establish both safety and patient satisfaction following outpatient submaxillectomies using active drains. Fifteen patients between March 2016 and March 2020 underwent submaxillectomies using active drains in an outpatient basis. No patient had to be readmitted, and there were no complications that could be associated with the outpatient basis of this procedure, showing the safety of this surgical regimen. Patient satisfaction degree was high, with 86.7% of the patients declaring low or no pain as well as appropriate hospital stay. Most of the patients stated that they would accept the surgery in an outpatient basis once again. The performance of an outpatient submandibular gland removal is a safe and well-accepted procedure by the patient.

Neonatal exposure to androgens dynamically alters gut microbiota architecture.

Gonadal steroids strongly contribute to the metabolic programming that shapes the susceptibility to the manifestation of diseases later in life, and the effect is often sexually dimorphic. Microbiome signatures, together with metabolic traits and sex steroid levels, were analyzed at adulthood in neonatally androgenized female rats, and compared with those of control male and female rats. Exposure of female rats to high doses of androgens on early postnatal life resulted in persistent alterations of the sex steroid profile later on life, namely lower progesterone and higher estradiol and estrone levels, with no effect on endogenous androgens. Neonatally androgenized females were heavier (10% at early adulthood and 26% at adulthood) than controls and had impaired glucose homeostasis observed by higher AUC of glucose in GTT and ITT when subjected to obesogenic manipulations. Androgenized female displayed overt alterations in gut microbiota, indicated especially by higher Bacteroidetes and lower Firmicutes abundance at early adulthood, which disappeared when animals were concurrently overfed at adulthood. Notably, these changes in gut microbiota were related with the intestinal expression of several miRNAs, such as miR-27a-3p, miR-29a-5p, and miR-100-3p. Our results suggest that nutritional and hormonal disruption at early developmental periods not only alters the metabolic programming of the individual later in life but also perturbs the architecture of gut microbiota, which may interact with the host by a cross-talk mediated by intestinal miRNAs; phenomena that may contribute to amplify the metabolic derangement caused by obesity, as seen in neonatally androgenized female rats.

OBJECTIVE: To analyze the status of the implementation and development of telepharmacy as applied to the pharmaceutical care of outpatients treated at hospital pharmacy services in Spain during the COVID-19 pandemic. METHOD: Six weeks after the beginning of the confinement period, an online 10-question survey was sent to all members of the Spanish Society of Hospital Pharmacists. A single response per hospital was requested. The survey included questions on the provision of remote pharmaceutical care prior to the onset of the health crisis, patient selection criteria, procedures for home delivery of medications and the means used to deliver them, the number of patients who benefited from telepharmacy, and the number of referrals made. Finally, respondents were asked whether a tele-consultation was carried out before sending patients their medication and whether these deliveries were recorded. RESULTS: A total of 39.3% (n = 185) of all the hospitals in the National Health System (covering all of Spain's autonomous regions) responded to the survey. Before the beginning of the crisis, 83.2% (n = 154) of hospital pharmacy services did not carry out remote pharmaceutical care activities that included telepharmacy with remote delivery of medication. During the study period, 119,972 patients were treated, with 134,142 deliveries of medication being completed. Most hospitals did not use patient selection criteria. A total of 30.2% of hospitals selected patients based on their personal circumstances. Home delivery and informed delivery (87%; 116,129 deliveries) was the option used in most cases. The means used to deliver the medication mainly included the use of external courier services (47.0%; 87 hospitals) or the hospital's own transport services (38.4%; 71 hospitals). As many as 87.6% of hospitals carried out teleconsultations prior to sending out medications and 59.6% recorded their telepharmacy activities in the hospital pharmacy appointments record. CONCLUSIONS: The rate of implementation of telepharmacy in outpatient care in Spain during the study period in the pandemic was high. This made it possible to guarantee the continuity of care for a large number of patients

Submental Perforator Flap for Soft-Tissue Reconstruction in Bisphosphonate-Related Osteonecrosis of the Jaws.

Bisphosphonate-related osteonecrosis of the jaws (BRONJ) has emerged as an important and increasingly common comorbidity, especially in patients undergoing long-term treatment with high doses of bisphosphonates. The management of BRONJ remains controversial. Surgical treatment is necessary in severe cases. Treatment of the bone requires sequestrectomy or resection. Given the lack of sufficient mucosa to perform the operation and fragility of margins in many patients, local flaps are crucial. We report two cases of stage-3 BRONJ presenting secondary infection with Actinomyces , receiving treatment consisting of marginal resection of the necrotic bone, reinforcement with a reconstruction plate, and reconstruction of soft tissues using a submental perforator artery flap ipsilateral to the lesion. Total cure was achieved in both cases, achieving favorable aesthetic and functional outcomes.

Local flap reconstruction of large scalp defects.

Scalp defects can have a number of origins, and their repair is dependent upon their location, size and depth. In the case of the scalp, the repair of even small defects is complicated. Local flaps are the reference for the reconstruction of such defects. Knowledge of scalp anatomy is essential for preparing these flaps, which must be based on one or two vascular pedicles to afford a large rotation angle--thereby facilitating closure of the defect. The parietal zone is the location offering the greatest flap mobilization possibilities. We present a case involving the repair of a major pericranial frontoparietal scalp defect. A local transverse posterior transpositioning scalp flap was raised with the posterior auricular and occipital arteries as vascular pedicle. Following repositioning of the flap, a free partial-thickness skin graft from the thigh was used to cover the donor zone. A review is provided of the different techniques for the reconstruction of large scalp defects.

Localized Leishmaniasis of the oral mucosa. A report of three cases.

The term leishmaniasis comprises a group of diseases caused by different species of a protozoon called Leishmania. Leishmaniasis is found worldwide, and is considered to be endemic in 88 countries. There are three main clinical forms of leishmaniasis: visceral leishmaniasis, cutaneous leishmaniasis and mucocutaneous leishmaniasis. Exclusive involvement of the mucosa is very rare. We present a series of three cases of mucosal leishmaniasis located in the oral cavity. The fact that all three cases were recorded in Spain (an area where L. infantum is endemic), suggests that the latter was the causal agent. The only manifestation of leishmaniasis disease in the described cases was the appearance of an oral lesion. Treatment was provided in the form of meglumine antimoniate in two patients, with a favorable response. One of the patients left the hospital after diagnosis, without receiving treatment, and the subsequent course is not known. A review is made of the literature on the subject.

Gingival neurofibroma in a neurofibromatosis type 1 patient.

Neurofibroma is a benign peripheral nerve sheath tumour. It is one of the most frequent tumours of neural origin and its presence is one of the clinical criteria for the diagnosis of type 1 neurofibromatosis (NF-I). Neurofibromatosis type 1 is an autosomal dominantly inherited disease due to an alteration in the long arm of chromosome 17. About 50% of NF-I patients have no family history of the disease. NF-I patients have skin lesions (cafe au lait spots and neurofibromas) as well as bone malformations and central nervous system tumours. Diagnosis is based on a series of clinical criteria. Gingival neurofibroma in NF-I is uncommon. Treatment of neurofibromas is surgical resection. The aim of this paper is to report a case of NF-I with gingival involvement and to review the literature.

El hecho de que todos los casos se produjeran en España, área endémica de L infantum, nos hace presuponer que éste fue el agente causal. La única manifestación de enfermedad de leishmaniasis en los casos descritos, fue la aparición de una lesión oral. Se administró tratamiento con antimoniato de meglumina en dos de ellos, respondiendo favorablemente. Uno de los pacientes abandonó el hospital tras el diagnóstico sin recibir tratamiento y se desconoce la evolución. Realizamos también una revisión de la literatura

Histiocitosis de Células de Langerhans en el área maxilofacial en adultos. Informe de tres casos / Langerhans cell histiocytosis in the maxillofacial area in adults. Report of three cases

La Histiocitosis de Células de Langerhans (HCL), es una enfermedad de etiología desconocida, que se caracteriza por la proliferación e infiltración anormal, de órganos, por células de Langerhans patológicas. Afecta predominantementea pacientes en edad pediátrica, siendo en adultos la incidencia de la enfermedad de uno a dos casos por millón de habitantes. Las manifestaciones en cabeza y cuello aparecen en casi un 90% de los casos. El diagnóstico se obtiene por medios anatomopatológicos, siendo necesarias una serie de pruebas, determinantes de extensión, en todos los pacientes diagnosticados de HCL. No existen estudios, controlados, que determinen un tratamiento óptimo para la HCL. El pronósticode esta enfermedad en adultos es generalmente bueno debido a la lenta evolución de la enfermedad y a su buena respuesta al tratamiento. Presentamos una revisión de tres casos de HCL, de 16, 24 y 28 años de edad, con manifestación primaria en el área Maxilofacial. Así mismo, realizamos una revisión de la literatura

Langerhans cell histiocytosis (LCH) is a disease of unknown etiology, characterized by proliferation of pathological Langerhans cells within different organs. It mainly affects children, but adult cases also occur, with an incidence rate of one to two per million. The head and neck are affected in almost 90% of cases. Diagnosis is made by means of histopathologicalanalysis, and imaging studies are necessary in order to determine extent of the disease. There are no controlled trials proposing an optimal treatment protocol for LCH. Prognosis in adults is generally good due to the slow evolution of the disease and its favourable response to treatment. In our report, we present three cases of LCH in patients aged 16, 24, and 28 years respectively, with primary manifestation in the maxillofacial area. A literature review was also conducted
