Evaluation of the efficacy of hydroxyl radical (OH˙) release for disinfection of the air and surfaces in the dental clinic: an in vitro study.

BACKGROUND: Concerning about the quality of room air has increased exponentially. Specially in dental clinics where diary practice is characterized by the important generation of aerosols. MATERIAL AND METHODS: An in vitro model was used in which samples were collected from the surfaces and room air of a dental clinic before and after the use of an OH˙ radical generator. RESULTS: A total of 1260 samples were collected for bacteriological analysis and 14 samples for the detection of SARS-CoV-2. Following OH˙ treatment, the tested surface samples showed a decrease in the number of colony forming units (CFUs) of 76.9% in TSA culture medium. The circulating room air samples in turn showed a decrease in CFUs of 66.7% in Sabouraud medium and 71.4% in Mannitol agar medium. No presence of SARS-CoV-2 was observed on the surface of the face shield. CONCLUSIONS: The disinfectant technology based on the use of hydroxyl radicals (OH˙) is effective in reducing the presence of moulds and yeasts and Staphylococcus in the air, and in reducing total aerobic bacteria on the tested surfaces.

Predictors of surgical difficulty in upper third molar removal: a prospective cohort study.

BACKGROUND: Upper third molar (U3M) removal is a common surgical procedure. The aims of this study were to assess the patient-specific, radiological and surgical factors related to the difficulty of U3M removal, and to determine the incidence of intraoperative and postoperative complications. MATERIAL AND METHODS: A prospective cohort study was carried out in adult patients undergoing U3M removal. Operative time, surgeon-reported difficulty and the Parant classification were used to assess extraction difficulty. Clinical, radiological and surgical factors were recorded to determine their relationship with surgical difficulty. A descriptive, bivariate and multivariate statistical analysis was carried out. RESULTS: A total of 250 patients were included. The mean operative time was 10.4 (±12.3) minutes, mean surgeon-reported difficulty was 3.2/10 (±2.3). The multivariate analysis showed greater impaction against the second molar and greater soft tissue and bony impaction to significantly increase operative time and surgeon-perceived difficulty. Additionally, surgeon experience was related to perceived difficulty. The overall incidence of intraoperative complications was 0.8%, and no postoperative events were recorded. CONCLUSIONS: Upper third molars in close relation with the roots of the adjacent second molar and with soft tissue and bony impaction are significantly more difficult to extract. Perceived difficulty was related to surgeon experience. This procedure appears to produce few intra- and postoperative complications.

Only 7 hospitals (16.7%) counted with occupational therapists (OT) (average dedication of 5 h/week). Each Rehab-session lasted 30 min on average.(AU)

Factores de riesgo asociados a infección periprotésica en el paciente con fractura del cuello femoral: estudio de casos y controles / Risk factors associated with periprosthetic infection in patients with femoral neck fracture: A case-control study

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)

Each Rehab-session lasted 30 min on average. 59.1% (n = 23) of the included hospitals had already implemented a specific post-covid follow-up rehab-consultation, whereas 9.1% (n = 4) of them were planning on implementing it. 64.3% (n = 24) of the surveyed centers implemented specific protocols for COVID-19 patients, while another 7.1% (n = 3) were in development progress. 48.5% (n = 18) of the surveyed centers did not owe its own specific training program within its ICUs and respiratory rehab-areas for the internal medical residents. CONCLUSIONS: The pandemic situation has resulted in a substantial increase on the workload in the Spanish Rehabilitation Services. Most of the hospitals included in the present study had already implemented outpatient follow-up consultations. Rehabilitation in critical patients is an exponentially recurrent topic for this medical specialty that needs to be furtherly addressed in the nearby future.

The impulsiveness level influences the salivary cortisol response and social stress sensitivity in suicidal patients.

INTRODUCTION: Suicide attempters (SA) are more vulnerable to social stress and show disturbed cortisol response in stressful conditions compared with psychiatric and healthy controls. Recent data suggest that this dysregulation might be related to impulsivity traits. However, little is known about the emotional consequences of social stress in SA exposed to stress. OBJECTIVES: The aim of our study was to evaluate the cortisol and emotional responses to social stress in patients with depression with and without suicide attempt, by taking into account impulsivity traits and depression severity. METHODS: 67 adult women (41 SA and 26 affective controls (AC,i.e. without suicide attempt history)) with lifetime history of major depressive episode were included. Patients performed the Trier Social Stress Test (TSST), a well-validated social stress task. Patients provided seven saliva samples, to measure the cortisol response, and filled in questionnaires to assess psychological pain, positive and negative mood, and anxiety at different time points (from 10 min before to 120 min after the TSST). Moderated regression models were used including suicide attempt history, depression severity, and impulsivity as independent variables and their interactions. RESULTS: In patients with low depression and high impulsivity, salivary cortisol response during the TSST was higher in SA than in AC (p < .001). Psychological pain, negative mood, and anxiety were increased in all patients just after the TSST, followed by a decrease at 120 min. Positive mood recovery was slower in SA, and in patients with high impulsivity and low depression level (p < .001). CONCLUSIONS: Impulsivity traits have an important role in suicidal vulnerability in stress conditions. Impulsivity traits might help to differentiate patients at risk of suicide who are highly sensitive to stress when depression level is low. Higher impulsiveness may increase the sensitivity to emotional distress that translates into inadequate physiological responses.

Sexual orientation, gender: Where is the problem? Nowhere! Correct self-identification and minority stigma.

PURPOSE: Self-concept, at the core of minority stress, is associated with negative mental health outcomes. METHODS: We aimed to assess the effectiveness of a one-shot third-wave CBT intervention targeting correct self-identification to address suffering related to minority stress. The study population included 172 participants (n = 98 heterosexuals, n=13 transgenders). The intervention consisted of a 90 minutes conference including overview of LGBT's suffering related to distal and proximal factors, a wisdom understanding of the root of suffering (mistaken self-identification) followed by a Questions & Answers session. Participants completed online self-questionnaires assessing sociodemographic data, acceptance by others (external) and oneself (internal) for sexual orientation and gender variables before the conference, immediately after the conference, and three months later. RESULTS: The conference helped to improve external acceptance of transgender for the whole sample, especially among the majority group. Those belonging to the minority (LGBT) had a positive benefit from the conference by reducing their fear of judgment. Adding a Q&A session to the conference failed to show any additional benefits. CONCLUSION: A specific wisdom-based self-identification conference appears to be an effective and low-cost intervention to target minority stigma, and therefore mental health and social integration of LGBT people.

[Influence of medical outliers in patients with femoral neck fracture]. / Influencia del ingreso hospitalario ectópico en pacientes con fractura del cuello femoral.

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.

Phases in the decision to request euthanasia and brain structures involved. / Fases en la decisión de solicitar la eutanasia y estructuras cerebrales involucradas.

INTRODUCTION: Euthanasia laws do not mention as an obstacle brain diseases other than dementia that damage circuits involved in decision-making. DEVELOPMENT: Narrative review of the stages of the decision to request euthanasia and the brain areas involved. The amygdala, the cingulate and insular cortex, and different parts of the prefrontal lobes are activated during decisions with similarities to that of requesting euthanasia. CONCLUSIONS: When an injury or malfunction of any of the structures involved in making decisions is known, a specific evaluation should be made of the influence it may have on the competence of the patient to request euthanasia.

Retinal arterial and venous obstruction as the first manifestation of an antiphospholipid antibody syndrome.

CASE REPORT: A 34 year-old woman presented with decrease in visual acuity in her right eye (RE). Her past medical history was unremarkable. Dilated fundus examination revealed a central venous occlusion and an obstruction of the cilioretinal artery. Given the patient age, a cardiology and haematology screen was obtained to rule out hypercoagulation disorders and thromboembolic disease. Antiplatelet, anticoagulant, and corticosteroid therapy were started. The laboratory result was positive for anticardiolipin and antiphospholipid antibody. A diagnosis of antiphospholipid syndrome (APS) was made. DISCUSSION: Antiphospholipid syndrome may cause thrombosis in any organ. The involvement of the retinal vessels may be the first manifestation of this entity. This diagnosis is important to prevent recurrent thrombotic events.

Retrograde filling material in periapical surgery: a systematic review.

BACKGROUND: Periapical surgery focuses on the treatment of teeth with persistent periapical lesions when orthograde root canal treatment fails. Although MTA® is the gold standard material for retrograde filling, Biodentine® - a tricalcium silicate-based cement - has been proposed in order to resolve several of its limitations. A systematic review has been carried out to compare the physicochemical properties of Biodentine® versus MTA® as root-end filling material in periapical surgery. MATERIAL AND METHODS: An electronic search was conducted by two independent examiners during March 2020 in the Cochrane, PubMed-MEDLINE and Scopus databases. In addition, a manual search was made in specialized journals. Comparative human or in vitro studies that evaluated bond strength, the presence of marginal gap and sealing ability were included. No restriction on publication date was applied. Animal studies, clinical cases, cases series and expert opinions were excluded. RESULTS: After analyzing 147 initially selected studies, 13 publications were included. Regarding bond strength, the studies seemed to evidence better performance of Biodentine® in both acidic and blood contaminated environments. In relation to the presence of marginal gap and sealing ability, the studies yielded contradictory results. According to some authors, the sealing ability of Biodentine® is greater than that of MTA® during the first 24 hours, though both materials prove equal after one week. Other authors recorded no significant differences. CONCLUSIONS: Considering the limitations and heterogeneity of the studies included, there is not sufficient evidence to confirm the clinical superiority of Biodentine® as a root-end filling material in periapical surgery.

Lipoteichoic acid depletion in Lactobacillus impacts cell morphology and stress response but does not abolish mercury surface binding.

Lipoteichoic acid (LTA) is a key component of the cell wall of most Gram-positive bacteria and plays many structural and functional roles. In probiotic lactobacilli, the function of LTA in mediating bacteria/host cross-talk has been evidenced and it has been postulated that, owing to its anionic nature, LTA may play a role in toxic metal sequestration by these bacteria. However, studies on this last aspect employing strains unable to synthesise LTA are lacking. We have inactivated the LTA polymerase encoding gene ltaS in two different Lactobacillus plantarum strains. Analysis of LTA contents in wild-type and ltaS mutant strains corroborated the role of this gene as a major contributor to LTA synthesis in L. plantarum. The mutant strains displayed strain-dependent anomalous cell morphologies that resulted in elongated or irregular cells with aberrant septum formation. They also exhibited higher sensitivity to several stresses (osmotic and heat) and to antimicrobials that target the cell wall. The toxicity of inorganic [(Hg(II)] and organic mercury (methyl-Hg) was also increased upon ltaS mutation in a strain-dependent manner. However, the mutant strains showed 0 to 50% decrease in their capacity of Hg binding compared to their corresponding parental strains. This result suggests a partial contribution of LTA to Hg binding onto the cell surface that was dependent on the strain and the Hg form.

Evolución de la incidencia de la enfermedad tromboembólica venosa en Galicia durante diez años (2006-2015) / Trends in the incidence of venous thromboembolism in Galicia over a ten year period

OBJETIVO: Analizar la tendencia evolutiva de episodios tromboembólicos graves en la Comunidad Autónoma de Galicia desde el 1 de enero de 2006 hasta el 31 de diciembre de 2015. MATERIAL Y MÉTODOS: Estudio observacional descriptivo en el Servicio Galego de Saúde durante 10 años (2006-2015). Se incluyeron pacientes con diagnóstico principal al alta de tromboembolismo pulmonar (TEP), ictus o trombosis venosa profunda (TVP). Fuente de datos: Servizo de admisión e documentación clínica, Subdirección de Información e Servizos Tecnolóxicos e Instituto Galego de Estatística. Variables de medida: número de casos nuevos de tromboembolismos acontecidos en un año, incidencia acumulada (número de casos nuevos/100.000 habitantes y año), mortalidad durante el ingreso hospitalario y porcentaje anual del cambio (APC). RESULTADOS: Se identificaron 50.611 eventos tromboembólicos. La mayor incidencia de tromboembolismo se encontró para ictus en hombres de 80 o más años con 940,84 casos nuevos por 100.000 habitantes/año. Todos los tromboembolismos fueron más frecuentes en hombres a excepción del TEP en mujeres jóvenes y las de mayor edad. El total de eventos tromboembólicos mostró un incremento continuo del 2,20% anual. La evolución temporal de la incidencia acumulada del TEP fue más pronunciada para mujeres entre 2006 y 2011 con un incremento anual del 10,65% y un aumento de menor magnitud a partir de 2011. La evolución de la incidencia acumulada del ictus mostró un APC de 1,56% en mujeres. CONCLUSIÓN: Este estudio pone de manifiesto un incremento en la tendencia evolutiva de los ingresos por TEP e ictus durante el periodo 2006-2015 en Galicia

OBJECTIVE: To analyse the trend of serious thromboembolic episodes in Galicia from 2006 to 2015. METHODS: A retrospective observational study was performed using the public network of the Galician Health Service over the 10 year period (2006-2015). It included patients with a primary diagnosis in their discharge report of pulmonary thromboembolism (PTE), stroke, or deep vein thrombosis (DVT). Data source: Servizo de admisión e documentación clínica, Subdirección de Información e Servizos Tecnolóxicos e Instituto Galego de Estatística. Measurement variables: the number of new cases of thromboembolism occurred in one year, cumulative incidence (number of new cases/ 100,000 persons years), mortality during hospital admission, and annual percentage change (APC). RESULTS: A total of 50,611 hospital admissions due to a venous thromboembolic event were identified. The highest incidence was found for stroke in men aged 80 years or older, with 940.84 new cases per 100,000 population per year. All thromboembolic events were more common in men, with the exception of PTE in young and older women. A continued increased was identified in all the thromboembolic events with an APC of 2.20%. The temporal evolution of the cumulative incidence for PTE was split into two segments, with an annual increase of 10.65% from 2006 to 2011, and a smaller increase since 2011. The cumulative incidence trend showed an APC for stroke of 1.56%. CONCLUSION: This study reveals an increase in the evolutionary trend of hospital admissions for PTE and stroke during the period 2006-2015 in Galicia

Suicidal ideation and affect lability in single and multiple suicidal attempters with Major Depressive Disorder: An exploratory network analysis.

INTRODUCTION: A better understanding of the specific contribution of risk factors to suicidal behavior could arise from analyzing suicidal ideation (SI) in clinical samples, and comparing single versus multiple suicide attempters through contemporary methods allowing complex and dynamical analyses of multiple and simultaneously interacting suicide risk factors. METHOD: We explored associations among suicidal ideation (SI), affect lability and other suicide risk factors in 323 suicidal attempters diagnosed with major depressive disorder (MDD). We analyzed the network structure and centrality of the total sample, and compared single versus multiple attempters and subjects with low and high suicidal ideation. RESULTS: SI was connected with anxiety (trait) and hopelessness. Central nodes for global and specific groups were affect lability (from anxiety to depression), anxiety as a trait, and harm avoidance. We observed some specific differences between clinical profiles of repeaters and non-repeaters and significant network density between high and low SI. LIMITATIONS: Because our cross-sectional design, we cannot establish casual relationships among variables. We only examined associations at group level but not at single subject level. CONCLUSIONS: Affect lability (mainly the shifts from anxiety to depression) and trait anxiety were central in each estimated network. These symptoms might be suitable targets for early detecting and treating suicidal patients.
