RESUMO
Antecedentes y objetivo: La infección es una de las complicaciones locales más importantes en el paciente con fractura del cuello femoral tratada con una artroplastia. El objetivo del presente estudio es describir y analizar posibles factores de riesgo que podrían estar implicados en la infección periprotésica del paciente con fractura del cuello femoral. Material y métodos: Se realizó un estudio de casos y controles retrospectivo que incluye a pacientes con fractura del cuello femoral tratada con una artroplastia en el periodo comprendido entre enero de 2015 y diciembre de 2017. Se definieron como casos a los pacientes con fractura del cuello femoral que tras someterse a una artroplastia (hemiartroplastia o artroplastia total de cadera) tuvieron como desenlace una infección periprotésica, cuyo diagnóstico se llevó a cabo atendiendo a los criterios mayores y menores descritos en el Consenso Internacional de Infecciones Musculoesqueléticas (Philadelphia 2018). Con la intención de atenuar la influencia de variables que podrían considerarse confusoras, se realizó un análisis multivariante. Resultados: Se apreció una asociación estadísticamente significativa entre infección periprotésica y determinadas variables presentes en el momento del ingreso, entre las que se encuentran la presencia de anemia moderada o severa (OR: 10,91; IC95%: 1,07-111,50; p=0,007), trombocitopenia (OR: 27,72; IC95%: 3,48-221,01; p=0,002), el antecedente tromboembólico (OR: 8,80; IC95%: 1,31-59,38; p=0,026), el trastorno ansioso-depresivo en tratamiento con 2 o 3 fármacos (OR: 21,36; IC95%: 3,65-125,12; p=0,001) y la hepatopatía (OR: 32,04; IC95%: 2,59-396,29; p=0,007). Conclusiones: La infección periprotésica en el paciente con fractura del cuello femoral tratado con una artroplastia podría relacionarse con la presencia de determinadas variables en el momento del ingreso hospitalario, entre las que se encuentran la anemia moderada o severa...(AU)
Background: Infection is one of the most important local complications in the patient with femoral neck fracture treated with arthroplasty. The aim of the present study is to describe and analyze possible risk factors that could be involved in periprosthetic infection in the patient with femoral neck fracture. Methods: A retrospective case-control study was performed including patients with femoral neck fractures treated with arthroplasty in the period between January 2015 and December 2017. Cases were defined as patients with femoral neck fracture who after undergoing arthroplasty (hemiarthroplasty or total hip arthroplasty) had a periprosthetic infection, whose diagnosis was carried out according to the major and minor criteria described in the International Consensus on Musculoskeletal Infections (Philadelphia 2018). In order to mitigate the influence of variables that could be considered confounding variables, a multivariate analysis was carried out. Outcomes: A statistically significant association was found between periprosthetic infection and certain variables present at the time of admission, including the presence of moderate or severe anaemia (OR: 10.91; 95%CI: 1.07-111.50; P=.007), thrombocytopenia (OR: 27.72; 95%CI: 3.48-221.01; P=.002), history of thromboembolism event (OR: 8.80; 95%CI: 1.31-59.38; P=.026), anxious-depressive disorder in treatment with two or three drugs (OR: 21.36; 95%CI: 3.65-125.12; P=.001) and liver disease (OR: 32.04; 95%CI: 2.59-396.29; P=.007). Conclusions: Periprosthetic infection in the patient with femoral neck fracture treated with arthroplasty could be related to the presence of certain variables at the time of hospital admission, including moderate or severe anaemia, thrombocytopenia, history of thromboembolic event, anxious-depressive disorder in treatment with two or three drugs or liver disease.(AU)

OBJECTIVES: The objective is to describe and analyze how outlier admission influences hospital stay and the appearance of complications in patients with a femoral neck fracture treated with arthroplasty. MATERIAL AND METHOD: A historical cohort study was carried out in which the group of patients with a displaced fracture of the femoral neck who had an outlier admission was defined as an exposed cohort, that is, they were admitted to a hospitalization area not belonging to the Orthopedic Surgery and Traumatology department, unlike the unexposed cohort, that included patients admitted to a hospitalization area assigned to the Orthopedic Surgery and Traumatology department. RESULTS: Outlier admission was a risk factor for requiring a postoperative transfusion (RR 1.52, 95% CI 1.05-2.21; P=.035), to have a postoperative stay longer than 5 days (RR 1.35, 95% CI 1.04-1.74; P=.038) and to suffer general postoperative complications (RR 1.35, 95% CI 1.02-1.78; P=.048). CONCLUSIONS: Outlier admission is a threat to the quality and safety of health care. In patients over 80 years of age, medical outliers is a risk factor for postoperative transfusion and systemic postoperative complications.

The authors analyzed the effect of several 15-amino acid peptides with sequences related to tumor-rejection antigens, tyrosinase, and the MAGE family on peripheral blood mononuclear cells from healthy donors cultured for periods of 1 to 7 days. Some of these peptides promoted stimulation of monocytes, manifested by phenotypic changes, release of interleukin (IL)-1a, IL-6, and tumor necrosis factor-alpha, and induction of nitric oxide synthase on differentiated CD14++/+ CD16+ DR++ monocytes. An increase in the percentage of cytotoxic monocytes (CD14+/- CD16+) containing granule-associated DNase activity was also observed. Active peptides induced the release of IL-2 and interferon-gamma. Nonspecific natural killer and lymphokine-activated killer cell-mediated cytotoxicity was also observed against classical target cell lines (K-562 and Daudi) and allogenic melanoma cell lines AC and BB, together with an increase in granule-associated DNase in the natural killer cell-enriched population. Monocytes were needed to enhance this innate response, because peptides failed to induce the release of IL-2 on monocyte-depleted peripheral blood mononuclear cells. Data show an enhancement of the rapid innate immune response by peptides related to tumor rejection antigens and suggest that they could also determine the nature of a slow and more definitive specific immune response against tumor cells.
