    Abstract Background: Nummular headache (NH) is defined by the presence of localized pain circumscribed to a round or elliptical area of the scalp, with a well-defined contour and a diameter of 1-6 cm. Although some evidence supports a peripheral mechanism, its etiopathogenesis remains unclear.
    Case: We report the case of a 64-year-old man with high-frequency episodic migraine who has used topiramate, beta-blockers, flunarizine, and amitriptyline without effect. In the last 8 years he also had continuous pain in an oval area of the scalp, consistent with NH. Triptans were ineffective for this new pain, and preventive therapy with gabapentin and onabotulinumtoxinA in the painful area had no effect. NH remitted when the patient received monthly treatment with subcutaneous galcanezumab for his migraine.
    Conclusions: Monoclonal antibodies against calcitonin gene-related peptide (CGRP), in particular galcanezumab, might be an effective therapy in some patients with NH. CGRP may have a role in the etiopathogenesis of this headache, which warrants further investigation.

    Abstract Background: Previous studies have shown worse cognitive performance in cluster headache (CH) patients compared to healthy controls; however, little is known about cognitive performance in episodic CH (ECH) patients outside and inside the active cluster (AC).
    Objective: Our aim is to compare cognitive function in ECH patients outside and inside the AC.
    Methods: In this cross-sectional, observational study, four neuropsychological tests (Trail Making Test [TMT], Stroop Test [ST], verbal fluency [VF], and Symbol Digit Modalities Test [SDT]) were completed by 21 ECH patients at two different points in time: outside and inside the AC. We also assessed self-reported sleep quality and the presence of anxiety or depressive symptoms. Scores were compared.
    Results: There was not any difference between the scores of the neuropsychological tests performed outside and inside the AC (TMT-A: 23 vs. 23.5; p = 0.984; TMT-B: 96.5 vs. 85.9; p = 0.104; ST word reading: 101.0 vs. 101.2; p = 0.938; ST color naming: 73.0 vs. 73.4; p = 0.858; ST color word: 44.0 vs. 46.0; p = 0.498; SDMT: 44.0 vs. 44.6; p = 0.961; VF phonemic: 29.5 vs. 30.2; p = 0.714; VF semantic: 20 vs. 21; p = 0.489). We found a worsening in the sleep quality component of the Pittsburgh Sleep Quality Index median scores in patients outside the AC (2 vs. 1; p = 0.046).
    Conclusions: Our findings suggest that patients with ECH have a similar cognitive performance outside and during the AC.

    Abstract Several studies have shown an association between psychosocial variables and functional capacity in chronic pain processes such as osteoarthritis. The aim of this study was to test a structural equations model that shows the predictive weight of certain variables such as catastrophizing, self-efficacy and kinesiophobia on functional pain and WOMAC subscales scores of pain and physical function of older patients diagnosed with hip and knee osteoarthritis. We also assessed the specific weight of age in terms of the factors. The study was conducted on a sample of 170 patients (142 women and 28 men mean age, 74.44 years range, 50-96 years). The main variables evaluated were WOMAC subscales scores of pain and physical function, self-efficacy, catastrophizing and kinesiophobia. To assess these variables, we used the Spanish validated version of the Western Ontario and McMaster Universities questionnaire, the Chronic Pain Self-Efficacy Scale, the Pain Catastrophizing Scale and the Tampa Scale for Kinesiophobia, respectively. We tested a structural equations model (IBM SPSS Amos version 22). The results showed the predominant predictive weight (both direct and indirect) of catastrophizing while simultaneously ruling out the relevance of age as a predictor of WOMAC subscales scores of pain and physical function. This study provides data of interest on the explanatory mechanisms that underlie the direct and inverse relationships between the studied psychological variables.

    Abstract Introduction: While there has been considerable progress in the development of vaccines against SARS-CoV-2, largely based on the S (spike) protein of the virus, less progress has been made with vaccines delivering different viral antigens with cross-reactive potential.
    Methods: In an effort to develop an immunogen with the capacity to induce broad antigen presentation, we have designed a multi-patch synthetic candidate containing dominant and persistent B cell epitopes from conserved regions of SARS-CoV-2 structural proteins associated with long-term immunity, termed CoV2-BMEP. Here we describe the characterization, immunogenicity and efficacy of CoV2-BMEP using two delivery platforms: nucleic acid DNA and attenuated modified vaccinia virus Ankara (MVA).
    Results: In cultured cells, both vectors produced a main protein of about 37 kDa as well as heterogeneous proteins with size ranging between 25-37 kDa. In C57BL/6 mice, both homologous and heterologous prime/boost combination of vectors induced the activation of SARS-CoV-2-specific CD4 and CD8 T cell responses, with a more balanced CD8
    Discussion: These findings revealed a novel immunogen with the capacity to control SARS-CoV-2 infection, using a broader antigen presentation mechanism than the approved vaccines based solely on the S antigen.

    Abstract Respiratory disorders caused by allergy have been associated to bronchiolar inflammation leading to life-threatening airway narrowing. However, whether airway allergy causes alveolar dysfunction contributing to the pathology of allergic asthma remains unaddressed. To explore whether airway allergy causes alveolar dysfunction that might contribute to the pathology of allergic asthma, alveolar structural and functional alterations were analyzed during house dust mite (HDM)-induced airway allergy in mice, by flow cytometry, light and electron microscopy, monocyte transfer experiments, assessment of intra-alveolarly-located cells, analysis of alveolar macrophage regeneration in

    Abstract Peritoneal immune cells reside unanchored within the peritoneal fluid in homeostasis. Here, we examined the mechanisms that control bacterial infection in the peritoneum using a mouse model of abdominal sepsis following intraperitoneal Escherichia coli infection. Whole-mount immunofluorescence and confocal microscopy of the peritoneal wall and omentum revealed that large peritoneal macrophages (LPMs) rapidly cleared bacteria and adhered to the mesothelium, forming multilayered cellular aggregates composed by sequentially recruited LPMs, B1 cells, neutrophils, and monocyte-derived cells (moCs). The formation of resident macrophage aggregates (resMφ-aggregates) required LPMs and thrombin-dependent fibrin polymerization. E. coli infection triggered LPM pyroptosis and release of inflammatory mediators. Resolution of these potentially inflammatory aggregates required LPM-mediated recruitment of moCs, which were essential for fibrinolysis-mediated resMφ-aggregate disaggregation and the prevention of peritoneal overt inflammation. Thus, resMφ-aggregates provide a physical scaffold that enables the efficient control of peritoneal infection, with implications for antimicrobial immunity in other body cavities, such as the pleural cavity or brain ventricles.

    Abstract The aim of this article is to study the influence of some printing parameters and postprocessing on mechanical properties of polylactic acid samples manufactured by fused deposition modeling with a 3D printer. The effects of different building orientations, concentric infill, and postprocessing by annealing were analyzed. In this sense, uniaxial tensile and three-point bending tests were performed to determine the ultimate strength, modulus of elasticity, and elongation at break. Among all printing parameters of interest, the print orientation can be considered one of the most important, being fundamental in the mechanical behavior. Once samples were fabricated, annealing processes were also considered, close to the

    Abstract We present two clinical cases, a 68-year-old male and a 55-year-old female, who are being studied for progressive solid food dysphagia. The initial gastroscopy revealed a polypoid lesion in the first case and a partially stenosing lesion in the second case. Both lesions were located in the mid-esophagus and presented a normal mucosa. Histological diagnosis confirmed an esophageal neuroendocrine carcinoma (NEC) of large cell and small cell types, respectively.

    Abstract Specific defense mechanisms against pathogens are fulfilled by different subsets of nonmucosal conventional dendritic cells (DCs), including migratory Langerhans cells (LCs), dermal DCs, and resident CD8(+) and CD8(-) DCs found in lymphoid organs. Dermal DCs capture antigens in the skin and migrate to lymph nodes, where they can transfer the antigens to CD8(+) DCs and activate CD4(+) T cells. Differential antigen-processing machinery grants CD8(+) DCs a high efficiency in activating CD8(+) T cells through crosspresentation, whereas CD8(-) DCs preferentially trigger CD4(+) T cell responses. Recent findings have revealed the important role played by monocyte-derived DCs (mo-DCs), newly formed during infection, in activating CD4(+) and CD8(+) T cells, regulating immunoglobulin production, and killing pathogens. However, a number of controversial issues regarding the function of different DC subsets during viral, bacterial, and parasitic infections remain to be resolved.

    Abstract Background: Cluster headache is one of the most disabling of all headache conditions. Although some studies have investigated the psychological profile of patients with cluster headache, research on its impact on cognitive function in patients with episodic cluster headache outside the cluster bout is scant.
    Methods: Cross-sectional study to evaluate various aspects of neuropsychological assessment and cognitive function including working memory, selective attention, verbal fluency, and executive function in 40 patients with episodic cluster headache. The patients were compared with 40 age-, gender-, and level of education-matched healthy controls.
    Results: Episodic cluster headache patients performed significantly worse than healthy controls on all cognitive tests, except for the Interference Score (P = 0.281). They had significantly higher Hospital Anxiety Scale scores (P = 0.002). However, we found no significant association between cognitive performance, anxiety, sleep quality, and disease duration.
    Conclusions: Patients with episodic cluster headache outside the bout showed worse executive functioning, working memory, language, and selective attention compared with healthy controls, regardless of the duration of disease or sleep quality.
