ABSTRACT
BACKGROUND: It has been documented that NSAIDs (nonsteroidal anti-inflammatory and antirheumatic drugs) reduce the effectiveness of some antihypertensive drugs. OBJECTIVE: Analyze the prescription of NSAID and the variables associated in outpatients with hypertension and explore some characteristics of the physicians. MATERIAL AND METHODS: Cross-sectional study, included patients with hypertension from the Family Medicine Unit No. 24 in Mante, Tamaulipas. From the patients, sociodemographic data, clinical history and pharmacological treatments were obtained. From the physicians, sociodemographic and academic information were collected. RESULTS: Mean age of the patients was 63 ± 11 years and 31.7% were prescribed NSAIDs. When compare exposed versus non-exposed to NSAIDs, being in uncontrolled high blood pressure, uncontrolled hypertension, multimorbidity and polypharmacy. The variables associated to the prescription of NSAIDs were: uncontrolled hypertension, multimorbidity and polypharmacy. The 56.7% of the physicians were women, 83.3% with experience >10 years and 33.3% with current certification by the Council in Family Medicine. CONCLUSIONS: The inappropriate prescription of NSAIDs revealed the need to implement actions to mitigate the potential risk for the hypertension patients to present a complication.

A new approach to ring-opening polymerization (ROP) based on C(sp3)-C(sp3) bond cleavage is reported. This process is based on the ability of Pd to promote both the ß-carbon elimination of a bifunctional cyclobutanol precursor and the C-C coupling process with the resulting Pd-alkyl intermediate. Consequently, novel polyketone materials are obtained. Owing to the modular synthesis of the used cyclobutanol monomers, the present ROP reaction allows the introduction of substitution patterns in the polymeric chain that are not accessible by current polyketone synthesis methodologies. We have explored in detail the initiation, propagation, and termination steps of this new polymerization process.
ABSTRACT
Cerebrospinal fluid opening pressure values are associated with various neurologic diseases; however, numerous factors can modify this measurement. This study aims to describe factors related to modifications in opening pressure measurements in pediatric patients. Methods: A retrospective analysis of lumbar punctures in pediatric patients conducted by the neuropediatrics group with institutional standardization. Bivariate and linear regression analyses were performed to determine the association between opening pressure and variables included in the study. Results: 544 events, median age 107 months, median opening pressure 19.7â cm H2O. Bivariate analysis found no association with medication use; anesthetics that increased opening pressure were remifentanil (P = .02) and propofol (P = .05), along with a positive linear correlation between opening pressure and age (P < .0001). Multiple linear regression analysis revealed that age, BMI, male gender, and remifentanil use were associated with an increase in opening pressure, whereas corticosteroid withdrawal was associated with a reduction in opening pressure. There is an interaction between age and headache, with an association with increased opening pressure up to around 140 months. Conclusion: This study identifies factors associated with changes in opening pressure, crucial for estimating normal opening pressure values in children. Headaches, anesthetic use, and corticosteroid withdrawal are confirmed as significant factors.

Mesenchymal stromal cells (MSC) have immunomodulatory and tissue-regenerative properties and have shown promising results in acute respiratory distress syndrome (ARDS) of multiple causes, including COVID-19. We conducted a randomised (1:1), placebo-controlled, double-blind clinical trial to assess the efficacy and safety of one bone marrow-derived MSC infusion in twenty patients with moderate to severe ARDS caused by COVID-19. The primary endpoint (increase in PaO2/FiO2 ratio from baseline to day 7, MSC 83.3 versus placebo 57.6) was not statistically significant, although a clinical improvement at day 7 in the WHO scale was observed in MSC patients (5, 50% vs 0, 0%, p = 0.033). Median time to discontinuation of supplemental oxygen was also shorter in the experimental arm (14 versus 23 days, p = 0.007), resulting in a shorter hospital stay (17.5 versus 28 days, p = 0.042). No significant differences were observed for other efficacy or safety secondary endpoints. No infusion or treatment-related serious adverse events occurred during the one-year follow-up. This study did not meet the primary endpoint of PaO2/FiO2 increase by day 7, although it suggests that MSC are safe in COVID-19 ARDS and may accelerate patients' clinical recovery and hospital discharge. Larger studies are warranted to elucidate their role in ARDS and other inflammatory lung disorders.Trial Registration: EudraCT Number: 2020-002193-27, registered on July 14th, 2020, https://www.clinicaltrialsregister.eu/ctr-search/trial/2020-002193-27/ES .

Extraterrestrial landing often requires firing a high-speed plume towards a planetary surface, and the resulting gas-granular interactions pose potential hazards to the lander. To investigate these jet-induced cratering dynamics, an experiment campaign covering a range of gas and granular properties relevant to the lunar and Martian environments was conducted in a large-scale vacuum chamber. Despite the variations in jet Mach number, mass flow rate, and composition of the granular phase investigated in this work, the observed time evolution of crater depth displays a consistent transition from an early-stage linear to a late-stage sublinear growth. To explain these scaling relations, a model that relates the kinetic energy gained by the particles per unit time to the power of the impinging jet is introduced. From this model, erosion rates and the critical depth at which the transition occurs can be extracted, and they are shown to depend on the gas impingement pressure, which was varied by changing ambient pressure, jet Mach number, mass flow rate, and nozzle height above the surface. These results highlight key mechanisms at work in the dynamics of plume-induced cratering and help to develop an understanding of optimal rocket engine firing times for future landings.
ABSTRACT
Massive irreparable cuff tears may represent as many as 20% to 40% of total cases of operated rotator cuff tears and can be a challenging clinical problem. Many treatment options have been proposed for their treatment. Among these options, latissimus dorsi tendon transfer can be considered a good alternative, especially in young patients before they develop glenohumeral arthritic changes. This technique aims at rebalancing the shoulder with a functioning subscapularis muscle and restoring both active external rotation and elevation with the aid of a properly functioning deltoid muscle. The modified arthroscopic latissimus dorsi transfer at the infraspinatus footprint with anterior extracortical fixation rebalances the pair of forces acting on the shoulder, stabilizing it in the transverse plane, minimizing the risk of latissimus dorsi transferred rupture and associated complications.
ABSTRACT
Este artículo presenta los resultados de una investigación cualitativa que indagasobre la implementación de la ley de interrupción del embarazo que despenalizó elaborto en tres causales específicas en Chile en 2017 (Ley 21.030) y el rol que laatención primaria de salud (APS) en la Región Metropolitana de Chile. Serealizaron 19 entrevistas a personal de la salud de la APS y del nivel secundariode atención en la Región Metropolitana además de dos personas del Ministerio deSalud.El cambio de régimen de penalización total a uno de despenalización por causalesexige capacitación a los equipos de salud e información a la población. Loshallazgos revelan que la falta de información y capacitación formal al personalsanitario constituye un obstáculo para el ejercicio de los derechos de las mujeresque otorga la ley, produciéndose un efecto cascada, en que las mujeres nocuentan con la información suficiente para ejercer sus derechos. A ello se suma,una disposición en la ley que produce confusión entre profesionales sobrepublicidad e información sobre los servicios. Se analizan los resultados a partir deestándares normativos nacionales e internacionales respecto a la obligación deinformar, y el derecho a ser informado en contexto de prestaciones sanitarias relativas al aborto.(AU)
Es va realitzar un estudi exploratori a través d'una enquesta a Comitès d'Ètica a països d'Amèrica Llatina i el Carib de parla hispana, per rellevar la seva situació davant d'emergències sanitàriesi consultar els dilemes ètics enfrontats a les investigacions per a COVID-19. S'obtingueren respostes de 106 comitès, pertanyents a 14 països. Només el 24% va respondre que existia una xarxa de comunicació eficient i efectiva entre comitès, prèvia a la pandèmia. El 45% va respondre que no existien a la seva regió comitès específics per avaluar projectes vinculats a emergències sanitàries amb anterioritat a la pandèmia. El percentatge de CEI que disposava de procediments previs per avaluar investigacions ensituacions d'emergències sanitàries va ser només de 7%, si bé el 52% estava en procés d'elaboració arran de la pandèmia. El percentatge de CEI que va considerar raonable un temps inferior a 5 dies per a l'avaluació de projectes de recerca va variar en virtut del disseny: 32% per als estudis observacionals i 12% per als assaigs clínics amb drogues o amb vacunes.Els tres problemes ètics principals identificats als estudis per a COVID van estar relacionats amb el consentiment informat, els aspectes metodològics i la poca informació prèvia o manca d'evidència per als productes de recerca. Considerem que cal reformular la manera de pensar els problemes ètics de les emergències cap a un abordatge global, amb un enfocament preventiu, on les xarxes de col·laboració entre els CEI haurien de convertir-se en regla.(AU)
This article presents the results of a qualitative research that inquiriesabout theimplementation of the law on termination of pregnancy that decriminalized abortionon three specific grounds in Chile in 2017 (Law 21.030) and the role of primaryhealth care (PHC) in the Metropolitan Region of Chile. Nineteen interviews wereconducted with PHC and secondary level of care health professionals in addition totwo officials from the Ministry of Health. The change from a regime of totalcriminalization to one of decriminalization by cause requires training for healthteams and information for the population.The findings reveal that the lack ofinformation and formal training for health personnel constitutes an obstacle to theexercise of women's rights under the law, producing a cascade effect in whichwomen do not have sufficient information to exercise their rights. In addition, thereis a provision in the law that causes confusion among professionals aboutadvertising and information on services.The results are analyzed on the basis ofnational and international normative standards regarding the obligation to informand the right to be informed in the context of health services related to abortion.(AU)

Anterior shoulder instability remains one of the main indications for shoulder surgery. We present a modified way of treating anterior shoulder instability in the beach-chair position from an anterior arthroscopic approach through the rotator interval. This technique opens the rotator interval, which increases the working area and allows us to work without cannulae. Through this approach, we can treat all injuries comprehensively and, if necessary, switch to other arthroscopic techniques used for instability such as arthroscopic Latarjet or anterior ligamentoplasties.
ABSTRACT
Fanconi anemia (FA) patients display an exacerbated risk of oral squamous cell carcinoma (OSCC) and oral potentially malignant lesions (OPMLs) at early ages. As patients have defects in their DNA repair mechanisms, standard-of-care treatments for OSCC such as radiotherapy and chemotherapy, give rise to severe toxicities. New methods for early diagnosis are urgently needed to allow for treatment in early disease stages and achieve better clinical outcomes. We conducted a prospective, longitudinal study wherein liquid biopsies from sixteen patients with no clinical diagnoses of OPML and/or OSCC were analyzed for the presence of mutations in cancer genes. The DNA from saliva and plasma were sequentially collected and deep-sequenced, and the clinical evaluation followed over a median time of approximately 2 years. In 9/16 FA patients, we detected mutations in cancer genes (mainly TP53) with minor allele frequencies (MAF) of down to 0.07%. Importantly, all patients that had mutations and clinical follow-up data after mutation detection (n = 6) developed oral precursor lesions or OSCC. The lead-time between mutation detection and tumor diagnosis ranged from 23 to 630 days. Strikingly, FA patients without mutations displayed a significantly lower risk of developing precursor lesions or OSCCs. Therefore, our diagnostic approach could help to stratify FA patients into risk groups, which would allow for closer surveillance for OSCCs or precursor lesions.

The reactions leading to the formation of C-heteroatom bonds in the coordination sphere of Au(III) complexes are uncommon, and their mechanisms are not well known. This work reports on the synthesis and reductive elimination reactions of a series of Au(III) methyl complexes containing different Au-heteroatom bonds. Complexes [Au(CF3)(Me)(X)(PR3)] (R = Ph, X = OTf, OClO3, ONO2, OC(O)CF3, F, Cl, Br; R = Cy, X = Me, OTf, Br) were obtained by the reaction of trans-[Au(CF3)(Me)2(PR3)] (R = Ph, Cy) with HX. The cationic complex cis-[Au(CF3)(Me)(PPh3)2]OTf was obtained by the reaction of [Au(CF3)(Me)(OTf)(PPh3)] with PPh3. Heating these complexes led to the reductive elimination of MeX (X = Me, Ph3P+, OTf, OClO3, ONO2, OC(O)CF3, F, Cl, Br). Mechanistic studies indicate that these reductive elimination reactions occur either through (a) the formation of tricoordinate intermediates by phosphine dissociation, followed by reductive elimination of MeX, or (b) the attack of weakly coordinating anionic (TfO- or ClO4-) or neutral nucleophiles (PPh3 or NEt3) to the Au-bound methyl carbon. The obtained results show for the first time that the nucleophilic substitution should be considered as a likely reductive elimination pathway in Au(III) alkyl complexes.
ABSTRACT
BACKGROUND: Lung cancer is one of the most lethal tumors with a poor survival rate even in those patients receiving new therapies. Metabolism is considered one of the hallmarks in carcinogenesis and lipid metabolism is emerging as a significant contributor to tumor metabolic reprogramming. We previously described a profile of some lipid metabolism related genes with potential prognostic value in advanced lung cancer. AIM: To analyze clinical and pathological characteristics related to a specific metabolic lipid genomic signature from patients with advanced lung cancer and to define differential outcome. METHODS: Ninety samples from NSCLC (non-small cell lung cancer) and 61 from SCLC (small cell lung cancer) patients were obtained. We performed a survival analysis based on lipid metabolic genes expression and clinical characteristics. The primary end point of the study was the correlation between gene expression, clinical characteristics and survival. RESULTS: Clinical variables associated with overall survival (OS) in NSCLC patients were clinical stage, adenocarcinoma histology, Eastern Cooperative Oncology Group (ECOG), number and site of metastasis, plasma albumin levels and first-line treatment with platinum. As for SCLC patients, clinical variables that impacted OS were ECOG, number of metastasis locations, second-line treatment administration and Diabetes Mellitus (DM). None of them was associated with gene expression, indicating that alterations in lipid metabolism are independent molecular variables providing complementary information of lung cancer patient outcome. CONCLUSIONS: Specific clinical features as well as the expression of lipid metabolism-related genes might be potential biomarkers with differential outcomes.

We report a neonatal patient with hypertrophic cardiomyopathy (HCM), lactic acidosis and isolated complex I deficiency. Using a customized next-generation sequencing panel, we identified a novel hemizygous variant c.338G>A in the X-linked NDUFB11 gene that encodes the NADH: ubiquinone oxidoreductase subunit B11 of the mitochondrial respiratory chain (MRC) complex I (CI). Molecular and functional assays performed in the proband's target tissuesskeletal and heart muscleshowed biochemical disturbances of the MRC, suggesting a pathogenic role for this variant. In silico analyses initially predicted an amino acid missense change p.(Arg113Lys) in the NDUFB11 CI subunit. However, we showed that the molecular effect of the c.338G>A variant, which is located at the last nucleotide of exon 2 of the NDUFB11 gene in the canonical 'short' transcript (sized 462 bp), instead causes a splicing defect triggering the up-regulation of the expression of an alternative 'long' transcript (sized 492 bp) that can also be detected in the control individuals. Our results support the hypothesis that the canonical 'short' transcript is required for the proper NDUFB11 protein synthesis, which is essential for optimal CI assembly and activity, whereas the longer alternative transcript seems to represent a non-functional, unprocessed splicing intermediate. Our results highlight the importance of characterizing the molecular effect of new variants in the affected patient's tissues to demonstrate their pathogenicity and association with the clinical phenotypes.

Lung cancer is one of the most deadly and common cancers in the world. The molecular features of patient's tumours dictate the different therapeutic decisions, which combines targeted therapy, chemotherapy, and immunotherapy. Altered cellular metabolism is one of the hallmarks of cancer. Tumour cells reprogram their metabolism to adapt to their novel requirements of growth, proliferation, and survival. Together with the Warburg effect, the role of lipid metabolism alterations in cancer development and prognosis has been highlighted. Several lipid related genes have been shown to promote transformation and progression of cancer cells and have been proposed as biomarkers for prognosis. Nevertheless, the exact mechanisms of the regulation of lipid metabolism and the biological consequences in non-small cell lung cancer (NSCLC) have not been elucidated yet. There is an urgent necessity to develop multidisciplinary and complementary strategies to improve NSCLC patients´ well-being and treatment response. Nutrients can directly affect fundamental cellular processes and some diet-derived ingredients, bioactive natural compounds and natural extracts have been shown to inhibit the tumour growth in preclinical and clinical trials. Previously, we described a supercritical extract of rosemary (SFRE) (12 - 16% composition of phenolic diterpenes carnosic acid and carnosol) as a potential antitumoral agent in colon and breast cancer due to its effects on the inhibition of lipid metabolism and DNA synthesis, and in the reduction of resistance to 5-FluoroUracil (5-FU). Herein, we demonstrate SFRE inhibits NSCLC cell bioenergetics identifying several lipid metabolism implicated targets. Moreover, SFRE synergises with standard therapeutic drugs used in the clinic, such as cisplatin, pemetrexed and pembrolizumab to inhibit of cell viability of NSCLC cells. Importantly, the clinical relevance of SFRE as a complement in the treatment of NSCLC patients is suggested based on the results of a pilot clinical trial where SFRE formulated with bioactive lipids (PCT/ES2017/070263) diminishes metabolic and inflammatory targets in peripheral-blood mononuclear cells (PBMC), such as MAPK (p=0.04), NLRP3 (p=0.044), and SREBF1 (p=0.047), which may augment the immune antitumour function. Based on these results, SFRE merits further investigation as a co-adjuvant in the treatment of NSCLC. Clinical trial registration: ClinicalTrials.gov Identifier NCT05080920.
ABSTRACT
Lactate dehydrogenase (LDH) catalyzes the reversible conversion of L-lactate to pyruvate. LDH-A deficiency is an autosomal recessive disorder (glycogenosis type XI, OMIM#612933) caused by mutations in the LDHA gene. We present two young adult female patients presenting with intolerance to anaerobic exercise, episodes of rhabdomyolysis, and, in one of the patients, psoriasis-like dermatitis. We identified in the LDHA gene a homozygous c.410C>A substitution that predicts a p.Ser137Ter nonsense mutation in Patient One and a compound heterozygous c.410C>A (p.Ser137Ter) and c.750G>A (p.Trp250Ter) nonsense mutation in Patient Two. The pathogenicity of the variants was demonstrated by electrophoretic separation of LDH isoenzymes. Moreover, a flat lactate curve on the forearm exercise test, along with the clinical combination of myopathy and psoriatic-like dermatitis, can also lead to the diagnosis.

Maxillofacial prosthesis is an effective treatment for patients with facial sequelae, but it remains challenging for professionals due to its high esthetic complexity. This study describes a clinical case of successful nasal prosthetic rehabilitation using digital technology and additive manufacturing. Initially, the 76-year-old patient, with a facial defect in the nasal region, had her face scanned with 3-dimensional scanner for laboratory planning of the prototype of a nasal prosthesis. After approving the prototype image, working models in muffle shape were obtained in additive manufacture for the inclusion of the prosthesis. In the final session, the prosthesis was colored extrinsically and installed. The procedures digital in the manufacture of the facial prosthesis was applicable and agile, allowing the professional greater predictability regarding the shape of the rehabilitated organ, esthetic improvement in the mutilated area and patient satisfaction in relation to the speed, of the procedure and the quality of the prosthesis.

Genital herpes is one of the most common sexually transmitted infections worldwide. It mainly affects women, as the rate of sexual transmission from male-to-female is higher than from female-to-male. The application of vaginal antivirals drugs could reduce the prevalence of genital herpes and prevent future infections. Layer-by-layer vaginal films were prepared by the solvent evaporation method using iota-carrageenan, hydroxypropyl methylcellulose and the polymethacrylates Eudragit® RS PO and Eudragit® S100, for the controlled release of acyclovir. The films were characterized by texture analysis and Raman spectroscopy. Swelling, mucoadhesion, and drug release studies were conducted in simulated vaginal fluid. The results show that Layer-by-Layer films exhibited adequate mechanical properties. The structuring of the layer-by-layer films allowed the controlled release of acyclovir and produced a prolonged mucoadhesion residence time of up to 192 h. The films formed in layer 2 by the combination of Eudragit® RS PO and S100 showed a controlled release of acyclovir for eight days, and adequate mechanical properties. These promising formulations for the prevention of genital herpes deserve further evaluation.
