Perspectives of people with HIV and HIV clinicians on characteristics of antiretroviral treatment and HIV-related symptoms.

OBJECTIVES: We aimed to assess HIV symptoms from the perspective of both patients and HIV specialists and the impact of discontinuing antiretroviral treatment (ART) on symptomology. We gathered opinions from HIV specialists and people living with HIV about ideal ART parameters and treatment satisfaction. METHODS: Ex post-facto cross-sectional surveys were administered to 502 people living with HIV and 101 HIV clinicians in Spain (18 sites). RESULTS: The median age of participants with HIV was 43.2 years, 74.5% were male, and 91.6% had an undetectable viral load. The mean time since initiation of ART was 10.2 years. Between 54% and 67% of people living with HIV reported experiencing nervousness or anxiety, sadness, fatigue, sleep problems, or muscle/joint pain during the preceding 4 weeks. However, only 22%-27% of specialists acknowledged the presence of these symptoms. The most bothersome symptoms were related to mental health or the central nervous system. There were significant differences between the burden of symptoms reported by people living with HIV and those acknowledged by specialists. The symptoms that more frequently caused ART discontinuation were depression, dizziness, and sleep problems. Both people living with HIV and specialists prioritized ART efficacy and low toxicity, but their importance ratings differed for 5 of the 11 ART characteristics assessed. People living with HIV rated their satisfaction with ART at a mean (± standard deviation) of 8.9 ± 1.5 out of 10, whereas HIV specialists rated it lower, at 8.3 ± 0.7 (p < 0.001). CONCLUSIONS: Despite advances in HIV care and treatment, a large proportion of patients still experience symptoms. HIV specialists may not be fully aware of these. People living with HIV and HIV specialists are, overall, satisfied with ART. However, the importance they place on different ART characteristics may vary.

First-Pass Effect in M1-Occlusion Stroke Patients Treated with Combined Stent-Retriever/Large-Bore Distal Aspiration Catheter Thrombectomy.

INTRODUCTION: Combined stent-retriever/large-bore distal aspiration catheter (LB-DAC) thrombectomy was recently introduced to treat large-vessel occlusion; however, it is unclear whether larger inner diameters improve outcomes. We compared angiographic and clinical outcomes in patients with occlusions of the M1 segment of the middle cerebral artery treated with mechanical thrombectomy using extra-LB-DAC versus LB-DAC in combination with stent-retrievers. METHODS: We analyzed consecutive patients with M1 occlusion included in the ROSSETTI registry treated with non-balloon guide catheter combined LB-DAC/stent-retriever thrombectomy between June 2019 and April 2022. We compared demographics, baseline clinical variables, procedural variables, angiographic outcomes, and clinical outcomes [National Institute of Health Stroke Scale score at 24 h (24h-NIHSS) and modified Rankin scale score at 3 months] between patients treated with extra-LB-DAC (Sofia Plus, MIVI Q6, Catalyst7; inner diameter, 0.068″-0.070″) versus LB-DAC (Sofia 5F, MIVI Q5, Catalyst 6; inner diameter, 0.055″-0.064″). Primary outcome was the first-pass effect (FPE) rate, defined as near-complete/complete reperfusion (mTICI 2c-3) after a single pass of the device. RESULTS: We included 324 patients (extra-LB-DAC, 185, 57.1% patients). Demographics, clinical data, and clinical outcomes were similar between the two groups; however, there was a trend towards improvement in National Institute of Health Stroke Scale score at 24 h (24h-NIHSS) in the cohort treated with extra-LB-DAC 9 points (IQR 4;16 points) vs. 12 points (IQR 4;18 points, P = 0.083). Patients treated with extra-LB-DAC had higher FPE rate (47% vs. 30.9%; P = 0.003) and higher modified FPE (mTICI ≥ 2b after a single pass) rate (65.9% vs 46.8%; P = 0.001). The use of extra-LB-DAC was an independent factor in predicting FPE (odds ratio 1.982, 95% confidence interval 1.250-3.143, P = 0.004). CONCLUSION: Our results suggest that in combined LB-DAC/stent-retriever thrombectomy, a larger aspiration catheter inner diameter is associated with higher rates of FPE and mFPE.

Cetylpyridinium Chloride Mouthwash to Reduce Shedding of Infectious SARS-CoV-2: A Double-Blind Randomized Clinical Trial.

The airborne transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via respiratory fluids and droplets suggests that mouthwashes containing substances with virucidal activity can help reduce viral spread. We conducted a multicenter, double-blind, placebo-controlled, randomized trial to assess the virucidal activity of cetylpyridinium chloride (CPC) mouthwashes. Outpatients who tested positive for SARS-CoV-2 infection with or without symptoms were randomized to perform washes and gargles for 1 min with 15 mL of either colored distilled water or 0.07% CPC (Vitis CPC Protect) mouthwash. The study outcomes were the SARS-CoV-2 log10 viral RNA load and the nucleocapsid protein levels, both in saliva at 1 and 3 h after the intervention. In total, 118 patients were enrolled and randomized (mean [SD], age 46 [14] y). Thirteen of 118 participants (11%) did not complete follow-up or had insufficient sample volume for testing and were excluded from the analysis. The assessment of the viral load showed no significant differences between groups at any of the investigated points. However, the levels of SARS-CoV-2 nucleocapsid protein of lysed viruses were significantly higher in the CPC group compared with the control group at 1 h (adjusted difference 269.3 pg/mL; 95% confidence interval [CI], 97.1-441.5) and at 3 h postintervention (561.1 pg/mL; 95% CI, 380.0-742.2). In nonhospitalized patients with asymptomatic or mild symptomatic SARS-CoV-2 infection, a 0.07% CPC mouthwash, compared to placebo, was associated with a significant increase of nucleocapsid protein levels in saliva, indicating enhanced disruption of viral particles.

SARS-CoV-2 infection. Descriptive analysis of a selected case series.

OBJECTIVES: COVID-19 was declared pandemic by March 2020. Clinical, analytical, and radiological findings have been reported. Detailed different evolution of patients of the same local outbreak has been scarcely reported. We report 6 selected cases of such an evolution. CLINICAL CASES: The clinical, radiological, analytical evolution of 6 patients is reported. Patients were selected as it were epidemiological close contacts, and showed particular different clinical evolution. RESULTS: The clinical course at the start of infection (first week) was similar among patients. In relationship with clinical evolution, middle to severe course were related with inflammation markers levels evolution (D-dimer, IL-6, ferritin, lymphocytes count, etc.). Specially lung alterations were observed, but neurological/neuropsychiatric findings are still common. In evolution, 2 patients showed middle symptoms, but the 2 most severely affected died. CONCLUSIONS: It remains to be elucidated the different evolutive pathways and outcomes of COVD-19. In our 6 patients of the same local outbreak, clinical, laboratory and radiological features were different. We discuss some aspects of the pathophysiology of the disease, other than the widely described of the respiratory system.

Objetivos: La COVID-19 fue declarada pandemia en marzo del 2020. Han sido comunicados los hallazgos clínicos, analíticos y radiológicos. Sin embargo, la diversa evolución de pacientes del mismo brote local lo ha sido escasamente. Comunicamos en este trabajo 6 casos seleccionados de tal evolución. Casos clínicos: Se expone la evolución clínica, radiológica y analítica de 6 pacientes. Estos fueron seleccionados ya que fueron epidemiológicamente contactos estrechos y mostraron una evolución clínica particularmente diferente. Resultados: El curso clínico al inicio de la infección (primera semana) fue similar entre los pacientes. En relación con la evolución clínica, un curso moderado a severo se relacionó evolutivamente con marcadores elevados de inflamación (dímero D, IL-6, ferritina, linfopenia, etc.). Fueron observadas alteraciones pulmonares típicas, pero fueron comunes también hallazgos neurológicos y neuropsiquiátricos. En la evolución 2pacientes mostraron síntomas moderados, pero los 2 más gravemente afectados murieron. Conclusiones: Está por elucidar las diferentes vías evolutivas y resultados finales de los pacientes con COVID-19. En nuestros 6 pacientes del mismo brote local, las características clínicas, de laboratorio y radiológicas fueron diferentes. Discutimos aspectos de la fisiopatología de la enfermedad distintos de los ampliamente descritos del sistema respiratorio.(AU)

Obesity status and obesity-associated gut dysbiosis effects on hypothalamic structural covariance.

BACKGROUND: Functional connectivity alterations in the lateral and medial hypothalamic networks have been associated with the development and maintenance of obesity, but the possible impact on the structural properties of these networks remains largely unexplored. Also, obesity-related gut dysbiosis may delineate specific hypothalamic alterations within obese conditions. We aim to assess the effects of obesity, and obesity and gut-dysbiosis on the structural covariance differences in hypothalamic networks, executive functioning, and depressive symptoms. METHODS: Medial (MH) and lateral (LH) hypothalamic structural covariance alterations were identified in 57 subjects with obesity compared to 47 subjects without obesity. Gut dysbiosis in the subjects with obesity was defined by the presence of high (n = 28) and low (n = 29) values in a BMI-associated microbial signature, and posthoc comparisons between these groups were used as a proxy to explore the role of obesity-related gut dysbiosis on the hypothalamic measurements, executive function, and depressive symptoms. RESULTS: Structural covariance alterations between the MH and the striatum, lateral prefrontal, cingulate, insula, and temporal cortices are congruent with previously functional connectivity disruptions in obesity conditions. MH structural covariance decreases encompassed postcentral parietal cortices in the subjects with obesity and gut-dysbiosis, but increases with subcortical nuclei involved in the coding food-related hedonic information in the subjects with obesity without gut-dysbiosis. Alterations for the structural covariance of the LH in the subjects with obesity and gut-dysbiosis encompassed increases with frontolimbic networks, but decreases with the lateral orbitofrontal cortex in the subjects with obesity without gut-dysbiosis. Subjects with obesity and gut dysbiosis showed higher executive dysfunction and depressive symptoms. CONCLUSIONS: Obesity-related gut dysbiosis is linked to specific structural covariance alterations in hypothalamic networks relevant to the integration of somatic-visceral information, and emotion regulation.

Overnight switch from levetiracetam to brivaracetam. Safety and tolerability.

Brivaracetam is a newer antiseizure medication than levetiracetam. It has a more selective action on the synaptic vesicle glycoprotein 2A binding site, and it seems to provide a more favorable neuropsychiatric profile. The aim of this study was to assess the safety and tolerability of an overnight switch from levetiracetam to brivaracetam. This was a retrospective descriptive study including patients with epilepsy treated with levetiracetam, who switched due to inefficacy or previous adverse events (AEs). In total, forty-one patients were included (mean age 40.9 ± 17.8 years, women 48.8%). Focal epilepsy represented 75.6% (n = 31) of patients (structural cause [n = 25], unknown cause [n = 6]). Four patients had idiopathic generalized epilepsy, two had developmental and epileptic encephalopathy and four patients were unclassified. The reason to start brivaracetam was inefficacy in 53.7% (n = 22), AEs in 65.9% (25/27 neuropsychiatric) and both in 19.5% (n = 8). Brivaracetam-related AEs were reported in 24.4%. Neuropsychological AEs associated with the previous use of levetiracetam improved in 76% of patients. Treatment was discontinued in 19.5% patients. Patients' reported seizure frequency improved, worsened and remained stable in 26.8%, 12.2%, and 61.0% of the cases, respectively. An overnight switching to brivaracetam is safe and well tolerated. This treatment can improve levetiracetam-related neuropsychiatric AEs.

Tranexamic acid in cardiac surgery: Are low doses enough?

OBJECTIVES: Tranexamic acid is used to prevent hyperfibrinolysis and reduce postoperative bleeding and blood transfusions in on-pump cardiac surgery. We evaluate the efficacy of low or high dose tranexamic acid in a prospective cohort study conducted in Valencia. MATERIALS AND METHODS: A total of 427 patients were recruited between January 2019 and January 2020, 207 in the Hospital General Universitario (low dose [LD]) and 220 in the Hospital Universitario y Politécnico La Fe (high dose [HD] and intermediate dose [ID]). We recorded the presence of hyperfibrinolysis on rotational thromboelastometry, intra- and postoperative administration of blood products, chest tube output within the first 12 h, and incidence of convulsions. Univariate and multivariate comparisons were performed. Univariate analysis of all categories was performed after propensity score matching between LD and HD and between LD and ID. RESULTS: There were no statistically significant differences in: appearance of hyperfibrinolysis, administration of blood products, postoperative chest tube output within the first 12 h, or occurrence of convulsions. Group LD received less fibrinogen than group HD (P = .014) and ID (P = .040) but more fresh frozen plasma than group ID (P = .0002). CONCLUSIONS: Administration of low-dose tranexamic acid is as effective as higher doses in hyperfibrinolysis prophylaxis and the prevention of postoperative bleeding in cardiac surgery.

RESULTS: There were no statistically significant differences in: appearance of hyperfibrinolysis, administration of blood products, postoperative chest tube output within the first 12h, or occurrence of convulsions. Group LD received less fibrinogen than group HD (P=.014) and ID (P=.040) but more fresh frozen plasma than group ID (P=.0002). CONCLUSIONS: Administration of low-dose tranexamic acid is as effective as higher doses in hyperfibrinolysis prophylaxis and the prevention of postoperative bleeding in cardiac surgery.

Treatment of advanced-stage canine nasal carcinomas with toceranib phosphate: 23 cases (2015-2020).

OBJECTIVE: To determine the median survival time (MST) of dogs with nasal carcinoma treated with toceranib phosphate. MATERIAL AND METHODS: The databases of four Spanish referral hospitals were retrospectively searched for dogs with a diagnosis of nasal tumours presented between January 2015 and October 2020. Dogs treated with radiotherapy or other chemotherapies prior toceranib were excluded. RESULTS: Twenty-three dogs with a confirmed nasal carcinoma treated with toceranib phosphate and with a CT scan for initial staging according to Adams Modified Staging System were included. Nine dogs had a stage III nasal carcinoma whereas 14 dogs had a stage IV nasal carcinoma. No dog had stages I and II nasal carcinoma. The median overall survival time was 139 days. The difference between the MST between dogs with stages III and IV was not statistically significant [P = 0.6, 140 days for stage III (range 46-401) vs 120 days for stage IV (range 23-600)]. Overall, dogs with epistaxis achieved a longer median survival (166 days) than dogs without epistaxis (83 days). Toceranib phosphate was generally well tolerated. Most dogs had an initial clinical benefit followed by progressive disease. SIGNIFICANCE: This is the first study to report the MST in dogs with stages III and IV nasal carcinoma treated with toceranib phosphate. This retrospective study showed that toceranib phosphate decreases the clinical signs associated with nasal carcinomas.

[Quality of life in adult patients with idiopathic generalised epilepsy. The EPILAK study]. / Calidad de vida en pacientes adultos con epilepsia generalizada idiopática. Estudio EPILAK.

INTRODUCTION: Quality of life (QoL) is an important aspect in the treatment of patients with epilepsy. AIM: To analyse the QoL using the Quality of Life in Epilepsy Inventory-10 (QOLIE-10) in adults with idiopathic generalised epilepsy and to study factors associated with a worse QoL. PATIENTS AND METHODS: A cross-sectional, multicentre, observational study conducted by 141 neurologists in all the autonomous communities of Spain. Each researcher analysed the QOLIE-10 of two males and two females over 18 years of age with idiopathic generalised epilepsy seen consecutively in public or private practice. The results were standardised: 0 was the worst QoL and 100 was the best. RESULTS: A total of 546 patients were analysed. Women: 51.1% (n = 279). Mean age: 36 ± 15.3 years old (18-87). Childhood absence seizures: 7.5% (n = 41); juvenile absence seizures: 9.2% (n = 50); juvenile myoclonic seizures: 29.8% (n = 163); only tonic-clonic seizures: 53.5% (n = 292). Monotherapy: 63.2% (n = 345). Seizure-free in the last year: 53.1% (n = 290). Psychiatric comorbidity: anxiety: 28.4% (n = 155); depression: 14.1% (n = 77); attention deficit: 10.1% (n = 55). Employment status: in active employment: 47.2% (n = 258); student: 20% (n = 109); housewife/husband: 7.3% (n = 40); pensioner: 10.2% (n = 56); unemployed: 14.3% (n = 78). Marital status: married or in a relationship: 49.1% (n = 268); single: 43.7% (n = 239). Mean score on the QOLIE-10: 71.4 ± 19.1. Being female (p = 0.006), greater frequency of seizures (p < 0.001), polytherapy (p < 0.001), psychiatric comorbidity (p < 0.001) and unemployment (p < 0.001) were significantly associated with a worse QoL. CONCLUSIONS: The QoL of patients with idiopathic/genetic generalised epilepsy is affected by poor seizure control, psychiatric comorbidity and unemployment, and women are more affected than men.

Clinical findings, neurological manifestations and survival of dogs with insulinoma: 116 cases (2009-2020).

OBJECTIVES: To review the clinical findings and outcome in dogs diagnosed with insulinoma, and to assess which factors are predictors of overall survival. Additionally, to describe the neurological manifestations of this population and their correlation with survival. MATERIALS AND METHODS: Retrospective multicentric study of canine insulinoma cases (2009 to 2020). Signalment, clinical history, neurological examination, diagnostic findings, treatment and outcome were obtained from clinical records. Univariate and multivariate analyses were used to compare the overall survival. RESULTS: One hundred and sixteen cases were included. Median duration of clinical signs before presentation was 1.5 months. The most common presenting clinical signs were weakness (59.5%), epileptic seizures (33.6%) and changes in consciousness or behaviour (27.6%). Three dogs were suspected to have paroxysmal dyskinesia. Thirty-two dogs had an abnormal neurological examination, most commonly showing obtundation (28.1%), decreased withdrawal reflexes (21.9%) and absent menace response (18.8%). Overall survival for dogs undergoing surgery (20 months) was significantly longer than in medically treated (8 months; adjusted hazard ratio: 0.33; 95% confidence interval: 0.18, 0.59). Presence of metastases was the only other variable associated with prognosis (adjusted hazard ratio 1.72; 95% confidence interval: 1.02, 2.91). CLINICAL SIGNIFICANCE: Clinical signs of canine insulinoma are vague and non-specific. Weakness, epileptic seizures and changes in mentation or behaviour were the most commonly reported. Obtunded mentation and forebrain neurolocalisation were the main neurological manifestations. Dogs undergoing surgery had a longer overall survival compared to medically treated cases, and dogs with metastasis had a shorter overall survival regardless of treatment modality. Abnormalities in the neurological examination did not correlate with prognosis.

Polypharmacy, functional outcome and treatment effect of intravenous alteplase for acute ischaemic stroke.

BACKGROUND AND PURPOSE: Polypharmacy is an important challenge in clinical practice. Our aim was to determine the effect of polypharmacy on functional outcome and treatment effect of alteplase in acute ischaemic stroke. METHODS: This was a post hoc analysis of the randomized, placebo-controlled WAKE-UP trial of magnetic resonance imaging guided intravenous alteplase in unknown onset stroke. Polypharmacy was defined as an intake of five or more medications at baseline. Comorbidities were assessed by the Charlson Comorbidity Index (CCI). The primary efficacy variable was favourable outcome defined by a score of 0-1 on the modified Rankin Scale at 90 days. Logistic regression analysis was used to test for an association of polypharmacy with functional outcome, and for interaction of polypharmacy and the effect of thrombolysis. RESULTS: Polypharmacy was present in 133/503 (26%) patients. Patients with polypharmacy were older (mean age 70 vs. 64 years; p < 0.0001) and had a higher score on the National Institutes of Health Stroke Scale at baseline (median 7 vs. 5; p = 0.0007). A comorbidity load defined by a CCI score ≥ 2 was more frequent in patients with polypharmacy (48% vs. 8%; p < 0.001). Polypharmacy was associated with lower odds of favourable outcome (adjusted odds ratio 0.50, 95% confidence interval 0.30-0.85; p = 0.0099), whilst the CCI score was not. Treatment with alteplase was associated with higher odds of favourable outcome in both groups, with no heterogeneity of treatment effect (test for interaction of treatment and polypharmacy, p = 0.29). CONCLUSION: In stroke patients, polypharmacy is associated with worse functional outcome after intravenous thrombolysis independent of comorbidities. However, polypharmacy does not interact with the beneficial effect of alteplase.

The utility of combined urine dipstick analysis and specific gravity measurement to determine feline proteinuria.

OBJECTIVES: To assess the utility of urine dipstick strips for detection of feline proteinuria when used in combination with urine-specific gravity, compared with urine protein-to-creatinine ratio as the gold standard. MATERIALS AND METHODS: Retrospective analysis of clinical records of comprehensive urine examination obtained from cats presented to a referral hospital. Diagnostic agreement and test accuracy were calculated for the dipstick test alone and in combination with the urine-specific gravity, using different cut-off values for proteinuria. Receiver-operating characteristic curves were also calculated. RESULTS: A total of 121 urine samples were included. The diagnostic agreement between dipstick and urine protein-creatinine ratio was poor. A dipstick result of equal or greater than "Trace" (0.1-0.3 g/L) had a sensitivity of 81% and a specificity of 31% to detect proteinuria. Grouping the samples by urine-specific gravity did not increase dipstick agreement with the urine protein-creatinine ratio and only resulted in a slight improvement in the accuracy of detecting proteinuria. CLINICAL SIGNIFICANCE: The dipstick test was not accurate for detecting proteinuria when combined with urine-specific gravity in cats. Clinicians should not rely on this test and, regardless of the urine concentration, other appropriate quantitative methods such as urine protein-creatinine ratio should always be performed to detect proteinuria in cats.

Patrones de prescripción de fármacos antihiperglucemiantes en pacientes ancianos en España: un estudio transversal nacional / Prescription patterns of antihyperglycemic drugs in elderly patients in Spain: a national cross-sectional study

ANTECEDENTES Y OBJETIVOS: Los pacientes ancianos con diabetes tipo 2 constituyen un grupo heterogéneo y creciente de sujetos en el que los objetivos terapéuticos y las prescripciones de los fármacos antihiperglucemiantes deben adaptarse a las enfermedades coexistentes y a su situación funcional y social. MÉTODOS: Realizamos un estudio transversal (desde febrero de 2014 a diciembre de 2014) para evaluar los patrones de prescripción y la inadecuación del tratamiento en pacientes con diabetes tipo 2 mayores de 65 años con al menos 6 meses de tratamiento con fármacos antihiperglucemiantes. RESULTADOS: Incluimos un total de 4.917 pacientes atendidos por 2.100 médicos de familia y 450 especialistas. Las prescripciones para la diabetes fueron monoterapia (21,2%), terapia dual (58,1%) y terapia triple (20,6%). Los patrones de prescripción más frecuentes fueron el de metformina en monoterapia (66,5%), metformina más inhibidores de la DPP-4 en terapia dual (77,3%) y, en terapia triple, fármacos orales (45,5%) y fármacos orales más insulina (45,8%). Un total de 1.272 (25,9%) pacientes presentaban riesgo de hipoglucemia grave, de los cuales 643 (50,6%) estaban en tratamiento con secretagogos (25%) o con insulina humana (25,6%). CONCLUSIONES: Los pacientes ancianos con diabetes tipo 2 reciben a menudo terapia antihiperglucemiante que comporta un alto riesgo de hipoglucemia. La sustitución de los secretagogos y de la terapia con insulina humana por una medicación más segura reduciría considerablemente los efectos secundarios del tratamiento de la diabetes en esta población

BACKGROUND AND OBJECTIVE: Elderly patients with type 2 diabetes represent a growing and heterogeneous group of subjects where treatment targets and antihyperglycemic drugs prescriptions should be tailored according to coexisting illnesses, functional and social domains. METHODS: We carried-out a national cross-sectional study (from February 2014 to December 2014) to assess prescription patterns and treatment inadequacy in patients with type 2 diabetes older than 65 years with at least 6 months of treatment with antihyperglycemic drugs. RESULTS: We included a total of 4,917 patients cared by 2,100 family physicians and 450 specialists. Diabetes prescriptions were monotherapy (21.2%), dual therapy (58.1%) and triple therapy (20.6%). The most common prescription patterns were metformin in monotherapy (66.5%), metformin plus DPP4 inhibitors in dual therapy (77.3%) and, in triple therapy, oral drugs (45.5%) and oral drugs plus insulin (45.8%). A total of 1,272 (25.9%) patients were at risk of serious hypoglycemia, 643 of them due to treatment with secretagogues (25%) or treatment with human insulin types (25.6%). CONCLUSIONS: Elderly patients with type 2 diabetes often receive antihyperglycemic therapy with higher risk of hypoglycemia. Substitution of secretagogues and human insulin therapy for safer medication could significantly reduce the adverse effects of diabetes treatment in this population
