Patient satisfaction with nursing care in an Intensive Care Unit measured through the Nursing Intensive-Care Satisfaction Scale (NICSS).

BACKGROUND: Patient satisfaction in relation with nursing care has become a key determinant of the quality of hospital care. OBJECTIVES: To evaluate patient satisfaction in relation with nursing care in a critical care context; to determine the correlation between critical patient satisfaction and sociodemographic and clinical variables and to describe patient perceptions with nursing care. METHODS: A descriptive, prospective, correlational study which includes the analysis of some open questions in the intensive care unit (ICU) of a tertiary level university hospital. The degree of satisfaction of all patients discharged from de ICU was evaluated. It was used the validated Spanish version of Nursing Intensive-Care Satisfaction-Scale (NICSS). There were also collected sociodemographic and clinical data and 3 open questions were asked. It was used the inferential and descriptive statistics considering statistically significant p<.05. Open questions were examined using a language context analysis. The approval of the hospital ethical committee was obtained. RESULTS: 111 patients agreed to participate, with a mean age of 64.18 years (CI 95% 61.36-66.88) and with a medium level of satisfaction of 5.83 (CI 95% 5.78-5.88) being 6 the maximum score. Women, older patients and those who reflect a higher degree of recovery, are those who reported greater satisfaction. Three main themes emerged from the analysis of the open-ended questions of the surveys: nurse patient relationship, professional practice environment and ICU nature. CONCLUSION: Patient satisfaction in relation with nursing care was elevated. Age, sex and degree of recovery significantly influenced their perception. Nurse patient relationship and the professional practice environment were aspects highlighted by patients. The professional model incorporated by the institution may encouraged these results.

Carbapenem alternatives for treatment of bloodstream infections due to AmpC producing enterobacterales.

INTRODUCTION: Carbapenems (CR) have traditionally been the first line treatment for bacteremia caused by AmpC-producing Enterobacterales. However, CR have a high ecological impact, and carbapenem-resistant strains continue rising. Thus, other treatment alternatives like Piperacillin-Tazobactam (P-T) or Cefepime (CEF) and oral sequential therapy (OST) are being evaluated. METHODS: We conducted a retrospective, single-centre observational study. All adult patients with AmpC-producing Enterobacterales bacteremia were included. The primary endpoint was clinical success defined as a composite of clinical cure, 14-day survival, and no adverse events. We evaluated the evolution of patients in whom OST was performed. RESULTS: Seventy-seven patients were included, 22 patients in the CR group and 55 in the P-T/CEF group (37 patients received CEF and 18 P-T). The mean age of the patients was higher in the P-T/CEF group (71 years in CR group vs. 76 years in P-T/CEF group, p = 0.053). In the multivariate analysis, age ≥ 70 years (OR 0.08, 95% CI [0.007-0.966], p = 0.047) and a Charlson index ≥ 3 (OR 0.16, 95% CI [0.026-0.984], p = 0.048), were associated with a lower clinical success. Treatment with P-T/CEF was associated with higher clinical success (OR 7.75, 95% CI [1.273-47.223], p = 0.026). OST was performed in 47% of patients. This was related with a shorter in-hospital stay (OST 14 days [7-22] vs. non-OST 18 days [13-38], p = 0.005) without difference in recurrence (OST 3% vs. non-OST 5%, p = 0.999). CONCLUSIONS: Targeted treatment with P-T/CEF and OST could be safe and effective treatments for patients with AmpC-producing Enterobacterales bacteremia.

Diagnosis and treatment of primary thyroid lymphoma from a surgical perspective: a multi-institutional study.

PURPOSE: Surgery of primary thyroid lymphoma (PTL) has been mostly limited to diagnostic work-up. This study aimed to further study its potential role. METHODS: This was a retrospective study from a multi-institutional registry of PTL patients. Clinical, diagnostic work-up (fine needle aspiration, FNA; core needle biopsy, CoreNB), contribution of surgery (open surgical biopsy, OpenSB; thyroidectomy), histology subtype, and outcome data were evaluated. RESULTS: Some 54 patients were studied. Diagnostic work-up included FNA in 47 patients, CoreNB in 11, and OpenSB in 21. CoreNB yielded the best sensitivity (90.9%). Thyroidectomy was performed in 14 patients with other diagnosis (incidental PTL), in 4 for diagnosis and in 4 for elective treatment of PTL. Incidental PTL was associated with not performed FNA nor CoreNB (OR 52.5; P = 0.008), mucosa-associated lymphoid tissue (MALT) subtype (OR 24.3; P = 0.012), and Hashimoto's thyroiditis (OR 11.1; P = 0.032). Lymphoma-related death (10 cases) mostly occurred within the first year after diagnosis and was associated with diffuse large B-cell (DLBC) subtype (OR 10.3; P = 0.018) and older patients (OR 1.08 for every 1-year increase; P = 0.010). There was a trend towards lower mortality rate in patients receiving thyroidectomy (2/22 versus 8/32, P = 0.172). CONCLUSION: Incidental PTL accounts for most of thyroid surgery cases and are associated with incomplete diagnostic work-up, Hashimoto's thyroiditis and MALT subtype. CoreNB appears to be the best tool for diagnosis. Most of PTL deaths occurred during the first year after diagnosis and mostly related to systemic treatment. Age and DLBC subtype are poor prognostic factors.

Gastrointestinal colonization by OXA-48-producing Enterobacterales: risk factors for persistent carriage.

Carbapenem-resistant Enterobacterales (CRE) infections are a major health problem. Intestinal colonization is a key factor in developing infection. However, factors associated with persistent colonization by CRE are unknown. The aim of the study was to identify factors associated with persistent CRE gut colonization. This is a retrospective, single-centre, observational study of adult patients with CRE gut colonization between January 2015 and January 2020. Epidemiologic characteristics, comorbidities, infectious events, duration of hospitalization and antimicrobial treatment received in the follow-up period were collected. Colonization was defined as isolation in at least 2 rectal swab culture samples of CRE. Decolonization was defined as 3 negative rectal swab cultures or 2 negative cultures and a negative molecular test. A cohort of 86 patients with CRE gut colonization was selected: 44 patients with spontaneous decolonization (DC) and 42 patients with persistent colonization (PC). The mean follow-up period was 24 months (IQR 14-33) in the DC group vs. 25 months (IQR 16-36) in the PC group (p = 0.478). Patient characteristics were similar between both groups. Colonization by other MDR microorganisms was high (44 patients, 51%) and slightly more common in the PC group (PC 60% vs. DC 43%, p = 0.139). The use of ceftazidime-avibactam was more common among the PC group (PC 33% vs. DC 14%, p = 0.041). We observed a higher percentage of antimicrobial therapy in the previous 30 days (PC 68% vs. DC 57%, p = 0.371) and 90 days (PC 81% vs. DC 82%, p = 0.353) in the PC group. Multivariable analysis showed that patients that have received ceftazidime-avibactam therapy (OR 4.9 95% CI [1.45-16.39], p = 0.010), and those colonized by other MDR microorganisms (OR 2.5, 95% CI [0.96-6.25], p = 0.060) presented a higher risk of PC. Ceftazidime-avibactam use and colonization by other MDR microorganisms might be associated with CRE persistent gut colonization.

Ceftazidime-avibactam treatment in bacteremia caused by OXA-48 carbapenemase-producing Klebsiella pneumoniae.

Therapeutic options for bacteremia caused by carbapenem-resistant Enterobacterales (CRE) OXA-48-type are limited. The objective of this study was to analyze clinical success of CAZ-AVI compared with best available therapy (BAT) in patients with Klebsiella pneumoniae carbapenemase-producing OXA-48-type bacteremia (CRKp-OXA-48). We conducted a retrospective, single-center observational study in adult patients with CRKp-OXA-48 between December 2015 and May 2019. We collected the patients' clinical and epidemiological characteristics, antibiotic treatment (CAZ-AVI vs. BAT), and evolution. Factors associated with clinical success were analyzed using binary logistic regression. The study included 76 patients with CRKp-OXA-48-type bacteremia 33 received CAZ-AVI and 43 BAT. CAZ-AVI was mainly used in monotherapy (91%). Clinical success was more common in patients < 70-year-old (OR 4.79, 95% CI [1.435-16.002], p = 0.011) and CAZ-AVI treatment (OR 6.69, 95% CI [1.68-26.604], p = 0.007). Kaplan-Meier survival curve of 14-day mortality showed a lower mortality in patients who received CAZ-AVI (log rank 0.013). However, CAZ-AVI did not achieve statistical difference in IPTW for 14- and 30-day mortality (aOR 0.1, 95% CI [0.02-1.22], p = 0.076 and aOR 1.7, 95% CI [0.48-5.98], p = 0.413, respectively). CAZ-AVI treatment might be associated with a greater clinical success in CRKp-OXA-48 bacteremia.

[Expert opinion on strategies to improve vaccination coverage against seasonal influenza]. / Documento de opinión de expertos para la mejora de la cobertura vacunal frente a la gripe estacional.

Seasonal flu continues to be a major public health concern, and the influenza vaccine remains the most effective preventive measure. In Spain, vaccination coverage data from previous seasons show vaccination rates well below official targets; however, these figures improved significantly after the COVID-19 pandemic. Given the importance of achieving and maintaining high vaccination rates in order to avoid the clinical and economic impact of influenza, our multidisciplinary group of experts on vaccines analyzed the impact of low vaccination rates in Spain and drafted a series of measures to boost influenza vaccination coverage, particularly among priority groups.

Differential analysis of the bacterial community in colostrum samples from women with gestational diabetes mellitus and obesity.

Gestational Diabetes Mellitus (GDM) and obesity affect the functioning of multiple maternal systems and influence colonization of the newborn gastrointestinal through the breastmilk microbiota (BMM). It is currently unclear how GDM and obesity affect the human BMM composition. Here, we applied 16S-rRNA high-throughput sequencing to human colostrum milk to characterize BMM taxonomic changes in a cohort of 43 individuals classified in six subgroups according to mothers patho-physiological conditions (healthy control (n = 18), GDM (n = 13), or obesity (n = 12)) and newborn gender. Using various diversity indicators, including Shannon/Faith phylogenetic index and UniFrac/robust Aitchison distances, we evidenced that BMM composition was influenced by the infant gender in the obesity subgroup. In addition, the GDM group presented higher microbial diversity compared to the control group. Staphylococcus, Corynebacterium 1, Anaerococcus and Prevotella were overrepresented in colostrum from women with either obesity or GDM, compared to control samples. Finally, Rhodobacteraceae was distinct for GDM and 5 families (Bdellovibrionaceae, Halomonadaceae, Shewanellaceae, Saccharimonadales and Vibrionaceae) were distinct for obesity subgroups with an absolute effect size greater than 1 and a q-value ≤ 0.05. This study represents the first effort to describe the impact of maternal GDM and obesity on BMM.

Role of Pneumocystis jirovecii in patients with different pulmonary underlying condition using a nested-PCR.

OBJECTIVE: The prevalence of Pneumocystis jirovecii colonization and its role in pulmonary disease remains unclear. PCR methods have shown an improved sensitivity in the detection of this fungus. It has been suggested that the PCR results be combined with another test such as IFA to create a diagnostic algorithm. METHODS: A multiplex nested-PCR procedure with a 16S rRNA gene as the internal amplification control was evaluated to determine the role of P. jirovecii in pulmonary disease. RESULTS: A 20% of the 199 bronchoalveolar lavage samples were PCR-positive, 13.5% samples were PCR-inhibited, and the rate of Pneumocystis-colonisation was 6.4%. The sensitivity, specificity, positive predictive value and negative predictive value of the nested-PCR were 100%, 93%, 70% and 100%, respectively. The sensitivity of the nested-PCR was higher than the current "gold standard" immunofluorescence assay (IFA) (p< 0.0001). PCR-negative and PCR-positive patients did not show any clinical or radiological differences in the medical variables studied. CONCLUSIONS: PCR could help the diagnosis of Pneumocystis pulmonary disease given the high negative predictive value of the technique. P. jirovecii DNA can frequently be detected in healthy population, so the analysis of the patient medical history is critical to make the correct clinical decision.

Neurorehabilitation and apps: A systematic review of mobile applications. / Apps en neurorrehabilitación. Una revisión sistemática de aplicaciones móviles.

INTRODUCTION: Mobile health or mHealth, defined as the provision of health information or healthcare by means of mobile devices or tablets, is emerging as a major game-changer for patients, care providers, and investors. An app is a program with special characteristics installed on a small mobile device, either a tablet or smartphone, with which the user interacts via a touch-based interface. The purpose of the app is to facilitate completion of a certain task or assist with daily activities. OBJECTIVE: The aim of this study was to conduct a systematic review of published information on apps directed at the field of neurorehabilitation, in order to classify them and describe their main characteristics. MATERIAL AND METHODS: A systematic review was carried out by means of a literature search in biomedical databases and other information sources related to mobile applications. Apps were classified into five categories: health habits, information, assessment, treatment, and specific uses. CONCLUSIONS: There are numerous applications with potential for use in the field of neurorehabilitation, so it is important that developers and designers understand the needs of people with neurological disorders so that their products will be valid and effective in light of those needs. Similarly, professionals, patients, families, and caregivers should have clear criteria and indicators to help them select the best applications for their specific situations.

Combining LCT tools for the optimization of an industrial process: material and energy flow analysis and best available techniques.

Life cycle thinking (LCT) is one of the philosophies that has recently appeared in the context of the sustainable development. Some of the already existing tools and methods, as well as some of the recently emerged ones, which seek to understand, interpret and design the life of a product, can be included into the scope of the LCT philosophy. That is the case of the material and energy flow analysis (MEFA), a tool derived from the industrial metabolism definition. This paper proposes a methodology combining MEFA with another technique derived from sustainable development which also fits the LCT philosophy, the BAT (best available techniques) analysis. This methodology, applied to an industrial process, seeks to identify the so-called improvable flows by MEFA, so that the appropriate candidate BAT can be selected by BAT analysis. Material and energy inputs, outputs and internal flows are quantified, and sustainable solutions are provided on the basis of industrial metabolism. The methodology has been applied to an exemplary roof tile manufacture plant for validation. 14 Improvable flows have been identified and 7 candidate BAT have been proposed aiming to reduce these flows. The proposed methodology provides a way to detect improvable material or energy flows in a process and selects the most sustainable options to enhance them. Solutions are proposed for the detected improvable flows, taking into account their effectiveness on improving such flows.

Livedoid vasculopathy and recurrent thrombosis in a patient with lupus: seronegative antiphospholipid syndrome?

Livedoid vasculopathy is a rare condition which predominantly affects young women. It is characterized by intense painful purpuric maculae in the legs, ankles and feet, due to thrombosis of the small and medium-sized dermal vessels, in the absence of vasculitis. Livedoid vasculopathy has been frequently associated with hypercoagulable states and antiphospholipid syndrome. We describe a 34-year-old White woman suffering from systemic lupus erythematosus, livedo reticularis, haemolytic anaemia, severe thrombocytopenia and recurrent venous thrombosis who was admitted to the hospital for extremely painful purpuric lesions in her lower limbs. The clinical and histological findings were diagnostic of livedoid vasculopathy. Once the initial sub-therapeutic international normalized ratio levels were corrected, livedoid vasculopathy did not recur. Tests for antiphospholipid antibodies were repeatedly negative. This case, the first reported of livedoid vasculopathy in a patient with seronegative antiphospholipid syndrome and systemic lupus erythematosus, draws attention to livedoid vasculopathy, a thrombotic dermopathy that may be under-diagnosed in patients with antiphospholipid syndrome.

Late infection of an embolized renal graft presented as buttock cellulitis.

Graft intolerance syndrome (GIS) is a common complication developed in failed kidney allografts left in situ when the patients returned to hemodialysis. GIS usually develops within the first 6 months after immunosuppression has been withdrawn. When medical treatment has failed, transplantectomy is the conventional therapy. Nevertheless, in recent years, transvascular ethanol embolization has been reported as an effective, safe, and less invasive technique than transplantectomy for the management of patients with GIS. Although infrequent, the most severe complication is infection of the graft or surrounding tissues, which usually appears in the first weeks after the procedure. We present the first case of late infection of an embolized renal graft, more than 2 years after embolization.

Biodegradable PCL scaffolds with an interconnected spherical pore network for tissue engineering.

A technique for producing controlled interconnected porous structures for application as a tissue engineering scaffold is presented in this article. The technique is based on the fabrication of a template of interconnected poly(ethyl methacrylate) (PEMA) microspheres, the introduction of a biodegradable polymer, poly-epsilon-caprolactone (PCL), and the elimination of the template by a selective solvent. A series of PCL scaffolds with a porosity of 70% and pore sizes up to 200 microm were produced and characterized (both thermally and mechanically). Human chondrocytes were cultured in monolayer on bulk PCL disks or seeded into porous PCL scaffolds. Cell adhesion, viability, proliferation, and proteoglycan (PG) synthesis were tested and compared with monolayer cultures on tissue-treated polystyrene or pellet cultures as reference controls. Cells cultured on PCL disks showed an adhesion similar to that of the polystyrene control (which allowed high levels of proliferation). Stained scaffold sections showed round-shaped chondrocyte aggregates embedded into porous PCL. PG production was similar to that of the pellet cultures and higher than that obtained with monolayer postconfluence cultures. This shows that the cells are capable of attaching themselves to PCL. Furthermore, in porous PCL, cells maintain the same phenotype as the chondrocytes within the native cartilage. These results suggest that PCL scaffolds may be a suitable candidate for chondrocyte culture.

Antihistaminic and antieicosanoid effects of oleanolic and ursolic acid fraction from Helichrysum picardii.

Helichrysum picardii Boiss. & Reuter is a Mediterranean vegetal species from the Asteraceae family. From the methanolic extract of the aerial flowering parts of this plant, a fraction of two pentacyclic triterpenes has been isolated. Gas chromatography revealed that the triterpene isomers ursolic and oleanolic acids comprised 69% and 29% respectively of the composition of this fraction. The triterpene isomeric fraction was tested in two phagocyte cell systems. It inhibited compound 48/80-induced histamine release from rat peritoneal mast cells in an approximately percentage of 45% at 100 microM and myeloperoxidase secretion from A23187-ionophore-stimulated rat peritoneal leukocytes in a significant manner at doses of 50 and 100 miroM. Furthermore, the triterpene isomers very significantly and dose-dependently inhibited generation of the cyclo-oxygenase metabolite prostaglandin E2 (41% inhibition at 50 miroM) and the 5-lipoxygenase metabolite leukotriene B4 (79% inhibition at 50 microM) from activated rat leukocytes. This anti-eicosanoid activity of the triterpene fraction was more potent than that produced by the pure triterpene oleanolic acid used for comparision, indicating a stronger action of the ursolic acid, the major compound of the isolated triterpene fraction. From these data, it can be suggested that the triterpene isomers oleanolic and ursolic acids present in the medicinal plant Helichrysum picardii contribute to the anti-inflammatory profile of this vegetal species.

Antiproliferative effects of mitraphylline, a pentacyclic oxindole alkaloid of Uncaria tomentosa on human glioma and neuroblastoma cell lines.

Uncaria tomentosa inner bark extract is a popular plant remedy used in folk medicine to treat tumor and inflammatory processes. In this study, the anti-tumoral effects of its pentacyclic alkaloid mitraphylline were investigated. Furthermore, its growth-inhibitory and cytotoxic effects on glioma GAMG and neuroblastoma SKN-BE(2) cell lines were studied using cyclophosphamide and vincristine as controls. A colter counter was used to determine viable cell numbers, followed by application of the tetrazolium compound [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)2-(4-sulfophenyl)-2H-tetrazolium], inner salt, colorimetric method to evaluate cell viability in this cytotoxicity assay. Micromolar concentrations of mitraphylline (from 5 to 40 microM) inhibited the growth of both cell lines. It inhibited the growth of the two cell lines studied in a dose-dependent manner. The IC(50) values were 12.3 microM (30h) for SKN-BE(2) and 20 microM (48 h) for GAMG, respectively. This action suggests that mitraphylline is a new and promising agent in the treatment of human neuroblastoma and glioma.
