Análisis del uso de los osteodilatadores para la creación del lecho implantológico: aportaciones técnicas y revisión de la literatura

La atrofia ósea severa del maxilar superior compromete e incluso, en ocasiones, impide la colocación de implantes. Con la expansión ósea mediante osteodilatadores se evita usar instrumentos rotatorios, no se produce calor ni se elimina hueso y se simplifica el tratamiento quirúrgico permitiendo la colocación de fijaciones sin recurrir a tratamientos más complejos. Presentamos una revisión de la técnica de expansión maxilar mediante osteodilatadores, describiendo las principales indicaciones, ventajas e inconvenientes de este procediminiento quirúrgico.Sometimes, the severe superior maxillary atrophy compromises and even impide oral implants treatment. The use of rotatory instruments (drills) produce heat and lost of bone, but the osteotomes in implantology avoid this and simplifies the surgical treatment allowing implant installation with an easier technique. We present an expansive maxillary technique review, describing the main indications, advantages and disadvantages of this surgical procedure

SARS-CoV-2 Delta-variant breakthrough infections in nursing home residents at midterm after Comirnaty® COVID-19 vaccination

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) Delta variant break-through infections in nursing home residents following vaccination with Comirnaty®COVID‐19 vaccine were characterized. In total, 201 participants (median age, 87 years;range, 64–100; 133 female) from two nursing homes in the Valencian community (Spain)were included. SARS‐CoV‐2‐Spike (S) antibody responses were determined by a lateralflow immunocromatography (LFIC) assay and by quantitative electrochemiluminescentassay in LFIC‐negative participants. SARS‐CoV‐2‐S‐IFNγT cells were enumerated by flowcytometry in 10 participants. Nasopharyngeal SARS‐CoV‐2 RNA loads were quantified byreal‐time polymerase chain reaction assays. Vaccine breakthrough COVID‐19 due to theDelta variant occurred in 39 residents (median age, 87 years; range, 69–96; 31 female) ata median of 6.5 months after vaccination (nine requiring hospitalization). Breakthroughinfections occurred at a higher rate(p< 0.0001) in residents who had not been previouslyinfected with SARS‐CoV‐2 (naïve) (33/108; 18%) than in those with prior diagnosis ofSARS‐CoV‐2 infection (experienced) (6/93; 6.4%), and were more likely (p< 0.0001) todevelop in residents who tested negative by LFIC (20/49) at 3 months after vaccinationas compared to their LFIC‐positive counterparts (19/142). Among LFIC‐negativeresidents, a trend towards lower plasma anti‐RBD antibody levels was noticed in thosedeveloping breakthrough infection (p=0.16).SARS‐CoV‐2 RNA loads in nasopharyngealspecimens were lower in SARS‐CoV‐2‐experienced residents (p< 0.001) and in thosetesting positive by LFIC (p=0.13). The frequency of SARS‐CoV‐2‐S‐reactive T cells at3monthswassimilarinLFIC‐negative residents with (n=7) or without (n=3)breakthrough infection. Prior history of SARS‐CoV‐2 infection and detection ofS‐reactive antibodies by LFIC at 3 months is associated with a lower risk of Delta‐variant breakthrough infection in nursing home residents at midterm after Comirnaty®COVID‐19 vaccination.We are grateful to the Vice‐presidency and Ministry of Equality andInclusive Policies of the Valencia Community, the Corporate Associationof Residences and Services for People with Dependency of the ValencianCommunity (AERTE), the Valencia Health System nursing homedepartmental committees, and the staff and residents of the participantnursing homes for their collaboration in developing the ProVaVacprogram.

La cinquena edició del microrelatari per l’eradicació de la violència contra les dones de l’Institut Universitari d’Estudis Feministes i de Gènere «Purificación Escribano» de la Universitat Jaume I vol ser una declaració d’esperança. Aquest és el moment en el qual les dones (i els homes) hem de fer un pas endavant i eliminar la violència sistèmica contra les dones. Ara és el moment de denunciar el masclisme i els micromasclismes començant a construir una societat més igualitària. Cadascun dels relats del llibre és una denúncia i una declaració que ens encamina cap a un món millor
