The role of testosterone in the pathophysiology of inflammation is of critical clinical importance; however, no universal mechanism(s) has been advanced to explain the complex and interwoven pathways of androgens in the attenuation of the inflammatory processes. PubMed and EMBASE searches were performed, including the following key words: “testosterone”, “androgens”, “inflammatory cytokines”, “inflammatory biomarkers” with focus on clinical studies as well as basic scientific studies in human and animal models. Significant benefits of testosterone therapy in ameliorating or attenuating the symptoms of several chronic inflammatory diseases were reported. Because anti–tumor necrosis factor therapy is the mainstay for the treatment of moderate-to-severe inflammatory bowel disease; including Crohn’s disease and ulcerative colitis, and because testosterone therapy in hypogonadal men with chronic inflammatory conditions reduce tumor necrosis factor-alpha (TNF-α), IL-1β, and IL-6, we suggest that testosterone therapy attenuates the inflammatory process and reduces the burden of disease by mechanisms inhibiting inflammatory cytokine expression and function. Mechanistically, androgens regulate the expression and function of inflammatory cytokines, including TNF-α, IL-1β, IL-6, and CRP (C-reactive protein). Here, we suggest that testosterone regulates multiple and overlapping cellular and molecular pathways involving a host of immune cells and biochemical factors that converge to contribute to attenuation of the inflammatory process.

Post-orgasmic illness syndrome (POIS) is an uncommon condition in which men experience debilitating symptoms following orgasm, including anxiety, weakness, and lassitude. The etiology is unknown, and treatment challenging. We present a 25y man with POIS since puberty. He dreaded ejaculation due to his subsequent symptoms. Multiple prior treatments had failed. Blood tests revealed testosterone (T) deficiency. hCG was prescribed. At 6 weeks T levels normalized with near-complete resolution of symptoms. This successful result argues for hormonal investigation in men with POIS, and a trial of hCG or T therapy if total or free T is low or borderline.

Seven patients with infected transvenous dual chambered pacemakers have undergone removal of the device using cardiopulmonary bypass. There were four women and three men with a mean age of 58 years. Six patients had localized infection in the generator pocket (mean of 4.6 previous unsuccessful operations for surgical sterilization). Four infections were due to Staphylococcus epidermidis, two to Staphylococcus aureus, and one patient presented septicemia caused by Staphylococcus epidermidis and Pseudomonas aeruginosa. The atrial and ventricular transvenous electrodes were removed under direct vision using cardiopulmonary bypass. A new dual chambered epicardial pacemaker was implanted. The procedure was well-tolerated, and all patients are infection free with working pacemakers after a mean follow-up of 25.4 months.

There is an actual need for developing materials for wound healing applications with anti-inflammatory, antioxidant, or antibacterial properties in order to improve the healing performance. In this work, we report the preparation and characterization of soft and bioactive iongel materials for patches, based on polymeric poly(vinyl alcohol) (PVA) and four ionic liquids containing the cholinium cation and different phenolic acid anions, namely cholinium salicylate ([Ch][Sal]), cholinium gallate ([Ch][Ga]), cholinium vanillate ([Ch][Van]), and cholinium caffeate ([Ch][Caff]). Within the iongels, the phenolic motif in the ionic liquids plays a dual role, acting as a PVA crosslinker and a bioactive compound. The obtained iongels are flexible, elastic, ionic conducting, and thermoreversible materials. Moreover, the iongels demonstrated high biocompatibility, non-hemolytic activity, and non-agglutination in mice blood, which are key-sought material specifications in wound healing applications. All the iongels have shown antibacterial properties, being PVA-[Ch][Sal], the one with higher inhibition halo for Escherichia Coli. The iongels also revealed high values of antioxidant activity due to the presence of the polyphenol, with the PVA-[Ch][Van] iongel having the highest activity. Finally, the iongels show a decrease in NO production in LPS-stimulated macrophages, with the PVA-[Ch][Sal] iongel displaying the best anti-inflammatory activity (>63% at 200 µg/mL).

Debido a la ausencia de un balance bibliográfico que sistematice el desarrollo que ha experimentado la diversidad sexual como temática de investigación aplicada al caso de Costa Rica, se hizo una revisión con el fin de procesar los textos a través de una base de datos, buscando describir y analizar sus características. Se encontró que durante el periodo analizado se ha incrementado el número de las investigaciones, cuya publicación se da principalmente en Costa Rica, proviniendo la mayor cantidad

Esta investigación tiene dos objetivos principales: sistematizar las discusiones teóricas con respecto al tema de ciudadanía sexual y proponer esta categoría de análisis para el abordaje de diferentes problemáticas asociadas a las políticas de sexualidad e identidad en Costa Rica. Mediante una revisión de fuentes periodísticas y estatales, se abordan diferentes coyunturas, principalmente en la década de 1990. Temas como el matrimonio igualitario y la creciente exposición de la diversidad sexual muestran que la ciudadanía sexual, como variable conceptual, puede ampliar el rango de estudio, al crear un diálogo entre las demandas por derechos, la canalización institucional de dichas demandas y la resolución usualmente insatisfactoria por parte del Estado para acatarlas.
