Factors Associated With Peripheral Nerve Injury After Pelvic Laparoscopy: The Importance of Surgical Positioning.

BACKGROUND: Nerve damage after abdominal and pelvic surgery is rare but potentially serious. The incidence of peripheral nerve injury is difficult to assess, and rates of between 0.02% and 21% have been cited in the literature. Signs and symptoms of this type of injury may appear immediately after surgery or a few days later. PURPOSE: This study was developed to assess the rate of peripheral nerve injury after pelvic laparoscopy and to identify associated risk factors. METHODS: A pilot prospective cohort study was conducted between March 2018 and April 2019 on 101 patients with a 1-month follow-up using two semistructured clinical interviews. We carried out a descriptive analysis followed by univariable and multivariable logistic regression analyses. RESULTS: Thirteen patients were found to have peripheral nerve injuries, representing a rate of 12.9%. Overall, 14 injuries (five severe and nine mild) were detected. One patient had two mild injuries. In this study, the risk of injury was found to increase 1.77-fold (OR = 1.77, 95% CI [1.13, 2.76], p = .007) for each hour the patient was in the Trendelenburg position. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The longer the patient is in the Trendelenburg position, the greater the risk of peripheral nerve damage. Patients aged 60 years or less also face a higher risk of nerve injury.

Influence of the COPD Assessment Test respiratory item score on the decision to hospitalize patients with disease exacerbation in a hospital emergency department. / Influencia de los ítems respiratorios del COPD Assessment Test (CAT) en la decisión de ingreso de las agudizaciones de enfermedad pulmonar obstructiva crónica (EPOC) atendidos en urgencias hospitalarias.

OBJECTIVES: The COPD Assessment Test (CAT) measures quality of life in patients with chronic obstructive pulmonary disease (COPD) as well as disease impact on activities of daily living. The questionnaire consists of 8 items related to breathing (cough, phlegm, chest tightness, and breathlessness) and other symptoms (low energy level, sleep disturbances, limitations on daily activities, and confidence when leaving the home). We investigated the relative impact of respiratory versus nonrespiratory scoring on the total CAT score at different moments in the course of COPD exacerbations: baseline (24 hours before an exacerbation), during the exacerbation, 15 days later, and 2 months later. To assess the influence of the respiratory item score on decisions to hospitalize patients treated for exacerbated COPD in our hospital emergency department (ED). MATERIAL AND METHODS: Prospective cohort study. We recruited patients who came to our ED for symptoms consistent with exacerbated COPD. Sociodemographic and clinical data were recorded. Clinical information, including treatments pleustarted in the ED and CAT scores, were also recorded. The event was defined as highly symptomatic if the patient's score was 3 points or higher on at least 3 of the 4 respiratory items at baseline. The outcome measures for the first objective were the total CAT score and item scores at the 4 time points before (baseline), during (ED), and after the exacerbation. The outcome for the second objective was hospital admission. RESULTS: A total of 587 patients were included. The mean (SD) total CAT score was 13.48 (7.29) at baseline, 24.86 (7.25) in the ED, 14.7 (7.47) at 15 days, and 13.45 (7.36) at 2 months. The respiratory item scores accounted for a mean 53.4% (20.76%) of the total score at baseline and 48.2% (11.47%) of the total score in the ED. Eighty-two patients (14.0%) were classified as being highly symptomatic. A total of 359 (61.2%) were admitted. Predictors of hospital admission were classification as highly symptomatic, odds ratio (OR, 3.045; 95% CI, 1.585-5.852, P .001), dyspnea at rest (OR, 2.906; 95% CI:1.943-4.346, P .001), and start of the following treatments in the ED: oxygen therapy (OR, 4.550; 95% CI, 3.056-6.773; P .0001), diuretic (OR, 1.754; 95% CI, 1.091-2.819; P = .02), and intravenous antibiotics (OR, 1.536; 95% CI, 1.034-2.281; P = .03). The model achieved an area under the receiver operating characteristic curve of 0.80 (95% CI, 0.763-0.836). CONCLUSION: Hospital admission from the ED is highly likely in patients with COPD exacerbation who have high baseline CAT scores, dyspnea at rest in the ED, and require oxygen therapy, diuretics, or intravenous antibiotics in the ED. The total CAT score and scores on respiratory items provide a tool for tailoring pharmacalogic and nonpharmacologic treaments and can facilitate follow-up evaluations.

OBJETIVO: El CAT (COPD Assessment Test) es un cuestionario de calidad de vida que mide el impacto que la enfermedad pulmonar obstructiva crónica (EPOC) está teniendo en el bienestar y vida diaria de los pacientes. Consta de 8 ítems divididos en 4 respiratorios y 4 no respiratorios. Conocer el impacto de las puntuaciones de los ítems respiratorios y no respiratorios en la puntuación CAT total, en diferentes momentos de la exacerbación de EPOC (24 horas antes de la exacerbación o basal, en la exacerbación, a los 15 días y a los 2 meses). Secundariamente, se valoró la influencia de los ítems respiratorios de la puntuación CAT total, en la decisión de ingreso de los pacientes atendidos por exacerbación de EPOC (EA-EPOC) en un servicio de urgencias hospitalario (SUH). METODO: Estudio de cohortes prospectivo. Se reclutaron pacientes que acudían al SUH con síntomas compatibles con EA-EPOC. La variable "Paciente respiratorio altamente sintomático"(PRAS) se definió como el paciente que tiene 3 puntos o más en al menos 3 de los 4 ítems respiratorios del CAT basal. Las variables de resultado fueron para el primer objetivo: la puntuación CAT total y desglosada por ítems, en los 4 momentos estudiados. Para el segundo objetivo fue el ingreso hospitalario. RESULTADOS: Se incluyeron 587 pacientes. La media de la puntuación CAT total basal fue 13,48 (7,29), en urgencias fue 24,86 (7,25), a los 15 días fue 14,7 (7,47) y a los 2 meses 13,45 fue (7,36). La proporción sobre la puntuación CAT basal total de los ítems respiratorios fue de 53,4% (20,76) y en el momento de llegar a urgencias del 48,2% (11,47). Los PRAS fueron 82 (14,0%). Ingresaron 359 pacientes (61,2%). Los predictores de ingreso hospitalario fueron: PRAS (OR 3,045, IC 95%: 1,585-5,852, p 0,001), disnea de reposo (OR 2,906, IC 95%: 1,943-4,346, p 0,001) y algunos tratamientos instaurados en el SUH (oxigenoterapia: OR 4,550, IC 95%: 3,056-6,773, p 0,001; diurético: OR 1,754, IC 95%: 1,091-2,819, p = 0,02; y antibiótico iv: OR 1,536, IC 95%: 1,034-2,281, p = 0,03). Este modelo logra un área bajo la curva COR de 0,80 (IC 95%: 0,763-0,836). CONCLUSIONES: En pacientes con EA-EPOC atendidos en urgencias, la alta puntuación de ítems respiratorios en el CAT basal, la disnea de reposo a su llegada al SUH y varios de los tratamientos instaurados en urgencias (oxigenoterapia, diuréticos y antibioterapia intravenosa) demostraron tener buena capacidad de predicción de ingreso hospitalario. La puntuación CAT total así como la puntuación en los ítems respiratorios del mismo son una herramienta que podría ayudar al clínico a individualizar el tratamiento o los controles posteriores.

Genomic Multiple Sclerosis Risk Variants Modulate the Expression of the ANKRD55-IL6ST Gene Region in Immature Dendritic Cells.

Intronic single-nucleotide polymorphisms (SNPs) in the ANKRD55 gene are associated with the risk for multiple sclerosis (MS) and rheumatoid arthritis by genome-wide association studies (GWAS). The risk alleles have been linked to higher expression levels of ANKRD55 and the neighboring IL6ST (gp130) gene in CD4+ T lymphocytes of healthy controls. The biological function of ANKRD55, its role in the immune system, and cellular sources of expression other than lymphocytes remain uncharacterized. Here, we show that monocytes gain capacity to express ANKRD55 during differentiation in immature monocyte-derived dendritic cells (moDCs) in the presence of interleukin (IL)-4/granulocyte-macrophage colony-stimulating factor (GM-CSF). ANKRD55 expression levels are further enhanced by retinoic acid agonist AM580 but downregulated following maturation with interferon (IFN)-γ and lipopolysaccharide (LPS). ANKRD55 was detected in the nucleus of moDC in nuclear speckles. We also analyzed the adjacent IL6ST, IL31RA, and SLC38A9 genes. Of note, in healthy controls, MS risk SNP genotype influenced ANKRD55 and IL6ST expression in immature moDC in opposite directions to that in CD4+ T cells. This effect was stronger for a partially correlated SNP, rs13186299, that is located, similar to the main MS risk SNPs, in an ANKRD55 intron. Upon analysis in MS patients, the main GWAS MS risk SNP rs7731626 was associated with ANKRD55 expression levels in CD4+ T cells. MoDC-specific ANKRD55 and IL6ST mRNA levels showed significant differences according to the clinical form of the disease, but, in contrast to healthy controls, were not influenced by genotype. We also measured serum sgp130 levels, which were found to be higher in homozygotes of the protective allele of rs7731626. Our study characterizes ANKRD55 expression in moDC and indicates monocyte-to-dendritic cell (Mo-DC) differentiation as a process potentially influenced by MS risk SNPs.
