Delphinol® standardized maqui berry extract reduces postprandial blood glucose increase in individuals with impaired glucose regulation by novel mechanism of sodium glucose cotransporter inhibition.

AIM: The impetus of our study was to investigate the effects of a nutritional supplement Delphinol®, an extract of maqui berries (Aristotelia chilensis) standardised to ≥25% delphinidins and ≥35% total anthocyanins, on postprandial blood glucose and insulin levels and identify the physiologic mechanism involved. METHODS: Postprandial blood glucose and insulin were investigated in double-blind, placebo-controlled, cross-over fashion in ten volunteers with moderate glucose intolerance. Longer term effects on blood sugar levels were investigated in streptozotocin-diabetic rats over a four months…

MISAGO 2: one-year outcomes after implantation of the Misago self-expanding nitinol stent in the superficial femoral and popliteal arteries of 744 patients.

PURPOSE: To evaluate the safety and efficacy of the Misago self-expanding rapid-exchange nitinol stent system for the treatment of femoropopliteal occlusive disease in a prospective multicenter observational trial (ClinicalTrials.gov; identifier NCT01118117). METHODS: Between April and October 2008, the registry enrolled 744 patients (496 men; 69 ± 10 years) who had symptomatic ≥ 70% stenosis or occlusion of the superficial femoral or popliteal arteries treated with the Misago stent. Mean length of the 750 lesions was 63.9 mm; 282 (37.6%) vessels were completely occluded. Primary study endpoi

Hybrid cardiac rehabilitation trial (HYCARET): protocol of a randomised, multicentre, non-inferiority trial in South America.

INTRODUCTION: Cardiac rehabilitation (CR) programmes are well established, and their effectiveness and cost-effectiveness are proven. In spite of this, CR remains underused, especially in lower-resource settings such as Latin America. There is an urgent need to create more accessible CR delivery models to reach all patients in need. This trial aims to evaluate if the prevention of recurrent cardiovascular events is not inferior in a hybrid CR programme compared with a standard programme. METHOD AND ANALYSIS: A non-inferiority, pragmatic, multicentre, parallel (1:1), prospective, randomised an

Clinicopathological and immunohistochemical evaluation of oral and oropharyngeal squamous cell carcinoma in Chilean population.

In oral and oropharyngeal squamous cell carcinoma (OCSCC and OPSCC) exist an association between clinical and histopathological parameters with cell proliferation, basal lamina, connective tissue degradation and surrounding stroma markers. We evaluated these associations in Chilean patients. A convenience sample of 37 cases of OCSCC (n=16) and OPSCC (n=21) was analyzed clinically (TNM, clinical stage) and histologically (WHO grade of differentiation, pattern of tumor invasion). We assessed the expression of p53, Ki67, HOXA1, HOXB7, type IV collagen (ColIV) and carcinoma-associated fibroblast (…

Switch to fixed-dose doravirine (100 mg) and islatravir (0·25 mg) once daily in virologically suppressed adults with HIV-1 on bictegravir, emtricitabine, and tenofovir alafenamide: 48-week results of a phase 3, multicentre, randomised, controlled, double-blind, non-inferiority trial.

BACKGROUND: The combination of doravirine and islatravir is under investigation as a fixed-dose, single-tablet regimen for the treatment of HIV-1. We aimed to assess the efficacy and safety of switching to doravirine (100 mg) and islatravir (0·25 mg) from bictegravir, emtricitabine, and tenofovir alafenamide in virologically suppressed adults with HIV-1. METHODS: This phase 3, randomised, controlled, double-blind, non-inferiority trial was conducted at 49 research, community, and hospital-based clinics in six countries: Australia, Chile, Israel, Japan, the UK, and the USA. Adults aged 18 year…

Safety, tolerability, and immunogenicity of an adult-specific pneumococcal conjugate vaccine, V116, in people living with HIV (STRIDE-7): a two-part, parallel-group, randomised, active comparator-controlled, international, phase 3 trial.

BACKGROUND: People living with HIV are at high risk of pneumococcal disease, and evidence of pneumococcal conjugate vaccine (PCV) safety and efficacy is needed. We aimed to evaluate the safety, tolerability, and immunogenicity of V116 (an adult-specific 21-valent PCV) in this population. METHODS: This two-part phase 3 trial was conducted at 20 centres in Belgium, Chile, France, South Africa, Thailand, and the USA.

Palate abnormalities in Chilean patients with chromosome 22q11 microdeletion syndrome.

OBJECTIVE: Chromosome 22q11 microdeletion syndrome (del22q11) is the most frequent microdeletion syndrome in humans, with an estimated incidence of 1/4000. It is recognized as a common identifiable cause of cleft palate. We characterized palatal abnormalities in a large cohort of Chilean patients with del22q11. METHODS: Patients with the deletion were evaluated by geneticists and speech pathologists, including nasopharyngoscopy when indicated. Comparisons between groups with and without palatal abnormalities were performed using Fisher's exact test and Mann-Whitney U test. RESULTS: Two hundr…

Diagnostic performance of GM-CSF and IL-2 in response to long-term specific-antigen cell stimulation in patients with active and latent tuberculosis infection.

BACKGROUND: A simple blood test for detecting active tuberculosis (TB) could be key to this epidemic containment, given that a large proportion of patients are unable to produce sputum for testing. Currently available interferon-γ release assays (IGRAs) are inadequate to diagnose active TB, with reported pooled sensitivity and specificity both under 81%. OBJECTIVE: To explore whether cytokines/chemokines other than interferon-γ in response to long-term cell stimulation could improve the ability to distinguish between different TB infection status. METHODS: We prospectively enrolled subjects

Y chromosome sequences in Turner's syndrome: association with virilization and gonadoblastoma.

UNLABELLED: The presence of Y chromosome fragments in patients with Turner's syndrome is known to increase the risk of gonadoblastoma and virilization. Y chromosome material is detected in up to 6% of patients with Turner's syndrome by karyotype. By DNA analysis, Y chromosome sequences have been reported in 0-60% of patients. The putative gonadoblastoma gene has been mapped to the pericentromeric region of the Y chromosome increasing the interest in studying these sequences. AIMS: 1. To determine the frequency of occult Y chromosome sequences in patients with Turner's syndrome. 2. To analyze

Incidental versus non-incidental gallbladder cancer: index cholecystectomy before oncologic re-resection negatively impacts survival in T2b tumors.

BACKGROUND: Conflicting data exists whether non-oncologic index cholecystectomy (IC) leading to discovery of incidental gallbladder cancer (IGBC) negatively impacts survival. This study aimed to determine whether a subgroup of patients derives a disadvantage from IC. METHODS: Patients with IGBC and non-IGBC treated at an academic USA and Chilean center during 1999-2016 were compared. Patients with T1, T4 tumor or preoperative jaundice were excluded. T2 disease was classified into T2a (peritoneal-side tumor) and T2b (hepatic-side tumor). Disease-specific survival (DSS) and its predictors were …

Postoperative adjuvant treatment for gastric cancer improves long-term survival after curative resection and D2 lymphadenectomy. Results from a Latin American Center.

BACKGROUND: The benefits of adjuvant treatment in the context of a D2 lymph node dissection are controversial. The aim was to investigate the effects of postoperative adjuvant treatment on the survival of patients with a curative resection for gastric cancer and a D2 lymph node dissection. METHODS: We performed a retrospective cohort study. Patients operated from 1996 to 2013 were selected. We compared long term survival of patients treated with surgery alone and those with surgery plus postoperative adjuvant treatment. A multivariate analysis for survival was applied in every stage. RESULTS
