RESUMEN
PURPOSE: A variable number of tandem repeats (VNTR) in the insulin gene (INS) control region may be involved in type 2 diabetes (T2D). The TH01 microsatellite is near INS and may regulate it. We investigated whether the TH01 microsatellite and INS VNTR, assessed via the surrogate marker single nucleotide polymorphism rs689, are associated with T2D and serum insulin levels in a Mexican population. METHODS: We analyzed a main case-control study (n = 1986) that used univariate and multivariate logistic regression models to calculate the risk conferred by TH01 and rs689 loci for T2D development; rs689 results were replicated in other case-control (n = 1188) and cross-sectional (n = 1914) studies. RESULTS: TH01 alleles 6, 8, 9, and 9.3 and allele A of rs689 were independently associated with T2D, with differences between sex and age at diagnosis. TH01 alleles with ≥ 8 repeats conferred an increased risk for T2D in males compared with ≤ 7 repeats (odds ratio, ≥ 1.46; 95% confidence interval, 1.1-1.95). In females, larger alleles conferred a 1.5-fold higher risk for T2D when diagnosed ≥ 46 years but conferred protection when diagnosed ≤ 45 years. Similarly, rs689 allele A was associated with T2D in these groups. In males, larger TH01 alleles and the rs689 A allele were associated with a significant decrease in median fasting plasma insulin concentration with age in T2D cases; the reverse occurred in controls. CONCLUSION: Larger TH01 alleles and rs689 A allele may potentiate insulin synthesis in males without T2D, a process disabled in those with T2D.

BACKGROUND: Osteonecrosis of the jaw (ONJ) has a frequent adverse effect after the administration of nitrogenous bisphosphonates, as non-nitrogenous bisphosphonates are metabolized more rapidly and would produce this effect to a lesser extent. The objective of this study is to analyze the results obtained in the literature with the use of L-PRF in the treatment of ONJ through a systematic review and meta-analysis. MATERIAL AND METHODS: Medline (via PubMed), Cochrane, Web of Science and Grey Literature Database was screened from which 10 were selected. RESULTS: In the meta-analysis with full resolution, combining the use of L-PRF in the treatment of ONJ, a weighted proportion (PP) of 94.3% of complete resolution is obtained (95% CI: 91.2-97.4, p<0.001), with a low degree of heterogeneity, statistically significant (I2 = 29.02%; p<0.001). When analyzing the non-resolution data, a weighted proportion (PP) of 7.7% (95% CI: 3.6-11.9; p<0.001) was obtained with moderate heterogeneity (I2: 41.87%; p=0.112). In the meta-regression, no significant correlation was found between complete resolution and year of publication (intercept = 2.88, p=0.829). In consistency analysis no major changes in PP are identified when any of the studies are eliminated, demonstrating a high reliability in the combined results. CONCLUSION: L-PRF alone or in combination with other therapies in treatment of ONJ achieved high percentages of complete lesion resolution (94.3%). In studies where L-PRF is combined with other therapies, and where the effectiveness of the other therapy alone is analyzed, L-PRF has been shown higher percentages of resolution.

BACKGROUND: Triple-negative breast cancer (TNBC) is associated with poor prognosis, and new treatment options are urgently needed. About 34%-39% of primary TNBCs show a low expression of human epidermal growth factor receptor 2 (HER2-low), which is a target for new anti-HER2 drugs. However, little is known about the frequency and the prognostic value of HER2-low in metastatic TNBC. PATIENTS AND METHODS: We retrospectively included patients with TNBC from five European countries for this international, multicenter analysis. Triple-negativity had to be shown in a metastatic site or in the primary breast tumor diagnosed simultaneously or within 3 years before metastatic disease. HER2-low was defined as immunohistochemically (IHC) 1+ or 2+ without ERBB2 gene amplification. Survival probabilities were calculated by the Kaplan-Meier method, and multivariable hazard ratios (HRs) were estimated by Cox regression models. RESULTS: In total, 691 patients, diagnosed between January 2006 and February 2021, were assessable. The incidence of HER2-low was 32.0% [95% confidence interval (CI) 28.5% to 35.5%], with similar proportions in metastases (n = 265; 29.8%) and primary tumors (n = 425; 33.4%; P = 0.324). The median overall survival (OS) in HER2-low and HER2-0 TNBC was 18.6 and 16.1 months, respectively (HR 1.00; 95% CI 0.83-1.19; P = 0.969). Similarly, in multivariable analysis, HER2-low had no significant impact on OS (HR 0.95; 95% CI 0.79-1.13; P = 0.545). No difference in prognosis was observed between HER2 IHC 0/1+ and IHC 2+ tumors (HR 0.89; 95% CI 0.69-1.17; P = 0.414). CONCLUSIONS: In this large international dataset of metastatic TNBC, the frequency of HER2-low was 32.0%. Neither in univariable nor in multivariable analysis HER2-low showed any influence on OS.

Resumen: Hallux rigidus es la patología degenerativa de la articulación metatarsofalángica del hallux. Esta patología provoca dolor y disminución en el movimiento. Existen múltiples tratamientos quirúrgicos para esta patología, todas con sus respectivas indicaciones. Presentamos el caso de un paciente de 54 años de edad con el diagnóstico de hallux rigidus quien tenía afectación únicamente del aspecto lateral de la cabeza del metatarsiano. Este paciente fue tratado con un procedimiento quirúrgico novedoso, se realizó una hemiartroplastía de interposición utilizando el extensor hallucis brevis asociado a una queilectomía y exostectomía. El paciente tuvo una favorable evolución clínica con mejoría evidenciado por escalas clínicas, con resolución de la sintomatología y sin complicaciones. La hemiartroplastía de interposición utilizando el extensor hallucis brevis es un tratamiento exitoso de preservación articular y del movimiento para el hallux rigidus en pacientes jóvenes en los que hay afectación unicompartimental lateral de la cabeza metatarsiana, en quienes es importante preservar el movimiento.
Abstract: Hallux rigidus is the degenerative pathology of the metatarsophalangeal joint of the hallux. This pathology causes pain and decreased movement. There are multiple surgical treatments for this pathology, all with their respective indications. We present the case of a 54-year-old patient diagnosed with hallux rigidus who had only the lateral aspect of the metatarsal head affected. This patient was treated with a novel surgical procedure, performing an interposition hemiarthroplasty using the hallucis brevis extender associated with a cheilectomy and exostectomy. The patient had a favorable clinical evolution with improvement evidenced by clinical scales, with resolution of the symptoms and without complications. Interposition hemiarthroplasty using the extensor hallucis brevis is a successful joint and movement preservation treatment for hallux rigidus in young patients with lateral unicompartmental involvement of the metatarsal head, in whom it is important to preserve movement.
RESUMEN
PURPOSE: There is no agreement in the literature on whether inferior alveolar nerve block (IANB) or infiltration (INF) is the anesthetic technique of choice for placing implants in the posterior mandible. This study aimed to compare the efficacy of the 2 techniques using articaine 4% with epinephrine 1:100,000. MATERIAL AND METHODS: The trial was a comparison between 2 parallel groups of patients, who received implants distal to the mental foramen, either with IANB or INF. The anesthetic technique was the predictor variable. The primary outcome was patients' perceived pain by a numerical rating scale (NRS) in incision, osteotomy and suture. The secondary outcome, patients' satisfaction, was equally recorded 12 hours after surgery. The dataset were first analyzed by descriptive statistics. Then, Mann-Whitney test, Spearman's coefficient, and regression models were used. This trial followed the recommendations of the Consort Statement for reporting randomized controlled trials (RCTs). RESULTS: Ninety-six patients (41 men, 55 women, mean age 55.76 years) were randomly assigned to either group, IANB or INF, of 48 patients each. Only 20% of patients reported pain values >0 (range 0-4 of 10). Medians were: 0 (0-0) for both groups (Pâ¯=â¯.956, .175 and .908, incision, osteotomy and suture, respectively). Mean satisfaction was high in both groups, 9.0 ± 1.0, median 10; and 8.8 ± 1.7, median 9, for IANB and INF (Pâ¯=â¯.695). Hence, the anesthetic technique did not generate statistically significant differences. Five potential influencing variables that were measured did not significantly affect pain levels or patient satisfaction in either group. CONCLUSIONS: According to the results, an IANB might not be necessary for standard implant surgery in the posterior mandible, and infiltration of articaine 4% with epinephrine 1:100,000 appears to be sufficient. Further research is needed to check if these results are extensible to other anesthetic drugs.

Background Immune checkpoint inhibitors (ICI) have been associated with several immune-related adverse events, including sarcoidosis-like reactions (SLR). SLR, which has a low prevalence but an increasing incidence, is similar to sarcoidosis in terms of histology, and clinical and radiological manifestations. The most commonly affected organs are hilar and mediastinal lymph nodes and skin. SLR is an exclusion diagnosis, so a lymph node biopsy can be useful to distinguish between tumor progression and SLR, particularly in tumors in which nodal involvement is very common. Patients and methods We performed a retrospective analysis of SLR in all cancer patients receiving ICIs in our institution between January 2016 and June 2020. Results Among the 1063 treated patients, seven experienced SLR, four of whom were symptomatic (cough, skin lesions, arthralgia), with time to onset ranging from 1.5 to 6.7 months after ICI initiation. All seven patients had bilateral hilar lymphadenopathy, and granulomatous reactions in five of the six patients with lymph node biopsies. SLR improved in all patients, including four patients who continued with ICI. Three patients received corticosteroids and/or stopped ICI therapy. Four of these patients had partial responses at the time SLR was identified. Conclusion Management of SLR lacks a consensus recommendation, although corticosteroids and/or stopping the ICI are generally implemented. The potential consequences of stopping anticancer treatment should be taken into consideration, particularly in the absence of clear management recommendations (AU)

INTRODUCTION: The COVID-19 pandemic has had a global impact, including in health services, placing health professionals under enormous tension, pressure, and stress. Professionals involved in the care, diagnosis, and treatment of COVID-19-infected patients have been subject to emotional and physical distress that can potentially enhance the development of occupational diseases. The aim of this study was to assess the impact of the COVID-19 pandemic on the incidence of burnout among Portuguese radiographers. METHODS: This was a cross-sectional, quantitative study. Burnout levels were estimated using the Maslach Burnout Inventory-Human Services Survey, composed of 22 questions. Specific questions were developed to characterize the socio-demographic situation and the impact of the pandemic on the radiographers. Data were descriptively analyzed and Mann-Whitney and Kruskal-Wallis tests were used for correlation analysis. RESULTS: The study sample comprised 386 radiographers, 68.7% of whom where female and 31.3% male. The mean sample age was 36.3 (±9.1) years. A total of 43.5% and 45.5% of subjects had a high level of emotional exhaustion and depersonalization, respectively, and 59.8% experienced low personal accomplishment. Altogether, 23.3% of study participants were at high risk of burnout in the three dimensions assessed and 77.2% in at least one. CONCLUSION: Study results showed that radiographers were at high risk of developing burnout in the COVID-19 pandemic setting. Health institutions should actively monitor these professional's mental health and develop restorative strategies that enable their emotional wellbeing, preventing absenteeism and increasing patients' quality of care. IMPLICATIONS FOR PRACTICE: Burnout of health professionals has a strong impact on health services organization, resulting in increased absenteeism and error probability, frequent work delays, low productivity and job satisfaction, inter- and intra-professional conflicts, high job turnover, high job quit, and decreased quality of care perceived by users.

Spinal cord injury is extremely debilitating, both at physiological and psychological levels, changing completely the patient's lifestyle. The introduction of biomaterials has opened a new window to develop a therapeutic approach to induce regeneration after injury due to similarities with extracellular matrix. Particularly, hydrogels have the ability to support axonal growth and endogenous regeneration. Moreover, they can also act as potential matrixes in which to load and deliver therapeutic agents at injury site. In this review, we highlight some important characteristics to be considered when designing hydrogels as delivery systems (DS), such as rheology, mesh size, swelling, degradation, gelation temperature and surface charge. Additionally, affinity-based release systems, incorporation of nanoparticles, or ion-mediated interactions are also pondered. Overall, hydrogel DS aim to promote a sustained, controlled and prolonged release at injury site, allowing a targeted oriented action of the therapeutic agent that will be used.

Aims The Watersports Inclusion Games (Inclusion Games) is a free event for children and families with disability to participate in water-based activities. Family participation in physical activity can improve mental health and confidence in children with disability. This study aims to gain an insight into the benefits and barriers of participation, perceived by parents and carers. Methods After an initial literature review, an online pre-event and post-event survey was constructed via SurveyMonkey. Both surveys were circulated three times to attendees. Statistical and thematic analysis was carried out to compare changes in responses both before and after the event. Results 49% of participants were primarily hoping to experience a new sport in a controlled environment and meet others with similar challenges. The surveys also highlighted an increase in reported family bonding [P=0.14] due to the event. A thematic analysis revealed event organisation and planning is vital for effective participation of children with disability. Conclusion Creating an equal opportunity for young people with disabilities and their families to partake in watersports led to increased confidence and a higher likelihood of future participation. Effective organisation and extra help were key enabling factors facilitating these benefits.

RESUMEN
INTRODUCTION: Heavy Menstrual Bleeding (EMB) is a frequent problem in adolescence. The prevalence of inherited bleeding disorders (IBD) as a cause of EMB is not well established and the involvement of fibri nolytic pathway defects has been poorly explored. OBJECTIVE: To determine the prevalence of IBD and fibrinolysis defects in adolescents with EMBs. PATIENTS AND METHOD: 93 adolescents (11 to 18 years old) were included. Personal and family history of bleeding were obtained through a standard ized questionnaire. The following lab tests were performed: prothrombin time (PT), activated partial thromboplastin time (aPTT), von Willebrand factor quantification, and platelet count and function. Those patients who were not diagnosed with IBD were further evaluated with clot lysis time assay. RESULTS: 41 patients (44%) were diagnosed as IBD (Von Willebrand disease n = 28, platelet func tion defects n=8, mild hemophilia n = 5. Decreased clot lysis time was found in 31 patients. 54% of patients diagnosed with IBD had EMB as the first hemorrhagic manifestation. CONCLUSION: These results support the need to evaluate the coagulation process, including the fibrinolytic pathway in the study of adolescents with EMB.

Resumen: Introducción: El Sangrado Menstrual Excesivo (SME) es un problema frecuente en la adolescencia. La prevalencia de trastornos hereditarios de la coagulación (THC) como causa del SME no está bien establecida y la participación de defectos de la vía fibrinolítica ha sido poco explorada. Objetivo: Determinar la prevalencia de THC y defectos de la fibrinólisis en adolescentes con SME. Pacientes y Método: Se incluyeron 93 adolescentes, edad 11 a 18 años. Los antecedentes personales y familiares de sangra do se obtuvieron con un cuestionario estandarizado. Se controló exámenes: tiempo de protrom- bina (TP), tiempo de tromboplastina parcial activada (TTPa), estudio del factor Von Willebrand, recuento y función plaquetaria. Los pacientes que no fueron diagnosticados como THC, se evaluaron adicionalmente con el tiempo de lisis del coágulo. Resultados: 41 pacientes (44%) fueron diagnos ticados como THC: Enfermedad de Von Willebrand n = 28, defectos de la función plaquetaria n = 8, hemofilia leve n = 5. Se confirmó disminución del tiempo de lisis del coágulo en 31 pacientes. El 54% de pacientes diagnosticado como THC, tuvo SME como la primera manifestación hemorrágica. Conclusión: Estos resultados apoyan la necesidad de evaluación de la coagulación, incluyendo la vía fibrinolítica, en el estudio de adolescentes con SME.

Mechanisms underlying affective and cognitive deficits in Parkinson's disease (PD) remain less studied than motor symptoms. Nucleus accumbens (NAc) is affected in PD and due to its well-known involvement in motivation is an interesting target in this context. Furthermore, PD is frequently asymmetrical, with side-specific deficits aligning with evidences of accumbal laterality. We therefore used a 6-hydroxydopamine (6-OHDA) model to study the role of left and right NAc dopamine depletion in a battery of behavioral tasks. 2 months old male rats were used in all experiments. Habitual-based and goal-directed decision-making, impulsivity, anxiety- and depressive-like behavior and motor performance were tested 3 weeks after left (6-OHDA L) or right (6-OHDA R) NAc lesion was induced. Upon contingency degradation, 6-OHDA R decrease their lever press rate less than Sham and 6-OHDA L, indicating an impairment in the shift from habit-based to goal-directed strategies. On the other hand, 6-OHDA L lesions lead to increased rates of premature responding when delays where increased in the variable delay-to-signal test. Importantly, in both paradigms task acquisition was similar between groups. In the same line we found no differences in the amount of sugared pellets eaten when freely available as well as in both general and fine motor behaviors. In conclusion, left and right NAc play distinct roles in the contingency degradation and impulsivity. More studies are needed to understand the mechanisms behind this functional lateralization and its implications for PD patients.

BACKGROUND: Patient-reported outcomes (PRO) and clinical outcomes give a broad assessment of relapsing-remitting multiple sclerosis (RRMS) disease. OBJECTIVE: The aim is to evaluate the effectiveness of delayed-release dimethyl fumarate (DMF) on disease activity and PROs in patients with RRMS in the clinic. METHODS: PROTEC, a phase 4, open-label, 12-month observational study, assessed annualized relapse rate (ARR), proportion of patients relapsed, and changes in PROs. Newly diagnosed and early MS (≤3.5 EDSS and ≤1 relapse in the prior year) patient subgroups were evaluated. RESULTS: Unadjusted ARR at 12 months post-DMF versus 12 months before DMF initiation was 75% lower (0.161 vs. 0.643, p < 0.0001) overall (n = 1105) and 84%, 77%, and 71% lower in newly diagnosed, ≤3.5 EDSS, and ≤1 relapse subgroups, respectively. Overall, 88% of patients were relapse-free 12 months after DMF initiation (84%, newly diagnosed; 88%, ≤3.5 EDSS; 88%, ≤1 relapse). PRO measures for fatigue, treatment satisfaction, daily living, and work improved significantly over 12 months of DMF versus baseline. CONCLUSION: At 12 months after versus 12 months before DMF initiation, ARR was significantly lower, the majority of patients were relapse-free, and multiple PRO measures showed improvement (overall and for subgroups), suggesting that DMF is effective based on clinical outcomes and from a patient perspective.Clinical trial: A Study Evaluating the Effectiveness of Tecfidera (Dimethyl Fumarate) on Multiple Sclerosis (MS) Disease Activity and Patient-Reported Outcomes (PROTEC), NCT01930708, https://clinicaltrials.gov/ct2/show/NCT01930708.
RESUMEN
La trombosis intracardíaca es una complicación poco frecuente en los pacientes que reciben asistencia hemodinámica mediante una membrana de oxigenación extracorpórea venoarterial (ECMO-VA), pero conlleva una elevada mortalidad. Este caso clínico describe un paciente que tuvo un shock cardiogénico tras un infarto agudo de miocardio con elevación del ST (IAMCEST) y que presentó trombosis intracardíaca durante la asistencia con ECMO-VA en 2 ocasiones: la primera en relación con la colocación de una prótesis mitral mecánica y la segunda tras el recambio por una prótesis mitral biológica
Intracardiac thrombosis is a rare complication in patients receiving haemodynamic support with venous-arterial extracorporeal membrane oxygenation (VA-ECMO), but it has a high risk of mortality. This case report describes a patient who suffered cardiogenic shock after a ST-segment elevation myocardial infarction (STEMI) and who presented with intracardiac thrombosis during VA-ECMO support on two occasions after mitral valve replacement. The first one was after the insertion of a mechanical prosthesis, and the second, after replacing it with a biological valve
