Summary Background Neurocysticercosis causes a substantial burden of seizure disorders worldwide. Treatment with either praziquantel or albendazole has suboptimum efficacy. We aimed to establish whether combination of these drugs would increase cysticidal efficacy and whether complete cyst resolution results in fewer seizures. We added an increased dose albendazole group to establish a potential effect of increased albendazole concentrations. Methods In this double-blind, placebo-controlled, phase 3 trial, patients with viable intraparenchymal neurocysticercosis were randomly assigned to receive 10 days of combined albendazole (15 mg/kg per day) plus praziquantel (50 mg/kg per day), standard albendazole (15 mg/kg per day), or increased dose albendazole (22·5 mg/kg per day). Randomisation was done with a computer generated schedule balanced within four strata based on number of cysts and concomitant antiepileptic drug. Patients and investigators were masked to group assignment. The primary outcome was complete cyst resolution on 6-month MRI. Enrolment was stopped after interim analysis because of parasiticidal superiority of one treatment group. Analysis excluded patients lost to follow-up before the 6-month MRI. This trial is registered with ClinicalTrials.gov, number NCT00441285. Findings Between March 3, 2010 and Nov 14, 2011, 124 patients were randomly assigned to study groups (41 to receive combined albendazole plus praziquantel [39 analysed], 43 standard albendazole [41 analysed], and 40 increased albendazole [38 analysed]). 25 (64%) of 39 patients in the combined treatment group had complete resolution of brain cysts compared with 15 (37%) of 41 patients in the standard albendazole group (rate ratio [RR] 1·75, 95% CI 1·10–2·79, p=0·014). 20 (53%) of 38 patients in the increased albendazole group had complete cyst resolution at 6-month MRI compared with 15 (37%) of 41 patients in the standard albendazole group (RR 1·44, 95% CI 0·87–2·38, p=0·151). No significant differences in adverse events were reported between treatment groups (18 in combined treatment group, 11 in standard albendazole group, and 19 in increased albendazole group). Interpretation Combination of albendazole plus praziquantel increases the parasiticidal effect in patients with multiple brain cysticercosis cysts without increased side-effects. A more efficacious parasiticidal regime without increased treatment-associated side-effects should improve the treatment and long term prognosis of patients with neurocysticercosis.

BackgroundThe incidence of candidemia is increasing in developing countries. Very little is known about the epidemiology of candidemia in Peru. The aim of this study is to describe the incidence, microbiology, clinical presentation and outcomes of Candida bloodstream infections in three Lima-Callao hospitals.MethodsCandida spp. isolates were identified prospectively at participant hospitals between November 2013 and January 2015. Susceptibility testing for amphotericin B, fluconazole, posaconazole, voriconazole and anidulafungin was performed using broth microdilution method. Clinical information was obtained from medical records and evaluated.ResultsWe collected information on 158 isolates and 157 patients. Median age of patients was 55.0 yrs., and 64.1% were males. Thirty-eight (24.2%) episodes of candidemia occurred in those <18 yrs. The frequency of non-Candida albicans was 72.1%. The most frequently recovered species were C. albicans (n = 44, 27.8%), C. parapsilosis (n = 40, 25.3%), C. tropicalis (n = 39, 24.7%) and C. glabrata (n = 15, 9.5%). Only four isolates were resistant to fluconazole, 86.7% (n = 137) were susceptible and 17 were susceptible-dose dependent. Decreased susceptibility to posaconazole was also observed in three isolates, and one to voriconazole. All isolates were susceptible to anidulafungin and amphotericin B. The most commonly associated co-morbid conditions were recent surgery (n = 61, 38.9%), mechanical ventilation (n = 60, 38.2%) and total parenteral nutrition (n = 57, 36.3%). The incidence of candidemia by center ranged between 1.01 and 2.63 cases per 1,000 admissions, with a global incidence of 2.04. Only 28.1% of cases received treatment within 72 hrs. of diagnosis. Overall, the 30-day survival was 60.4% (treated subjects, 67.4%; not-treated patients, 50.9%).ConclusionsWe found a very high proportion of non-albicans Candida species. Despite this, the decreased susceptibility/resistance to fluconazole was only 13.3% and not seen in the other antifungals. Overall, the incidence of candidemia mortality was high when compared to other international studies. It is possible, that the delay in initiating antifungal treatment contributed to the elevated mortality rate, in spite of low antifungal resistance.

In patients with human immunodeficiency virus, the diagnosis of neurocysticercosis can be complex, and the current diagnostic criteria may not apply. We report 3 cases and suggest including the CD4+ T lymphocyte count as an important factor in the proper diagnosis and treatment of patients with human immunodeficiency virus and potential neurocysticercosis.

Introduction Lipoprotein A (LpA) has been shown to be an emerging risk factor, proposing that values greater than 60 mg/dl increases cardiovascular risk. There are few data about LpA values in young patients who have suffered a major cardiovascular event. Purpose The objective of this work was to describe the LpA values observed in young patients admitted for acute coronary syndrome in our center, and subsequently to compare these values according to the patients' previous cardiovascular risk. Methods This is a descriptive and observational study, in which all male patients under 65 years and women under 70 years who have suffered STEMI or NSTEMI from November 2019 to February 2021 admitted to our center were consecutively included. In addition to LpA values, the following variables were recollected: age, sex, high blood pressure, diabetes mellitus, dyslipidemia, stroke, chronic kidney injury, smoking, alcoholism, toxics, total cholesterol and SCORE risk. Results 159 patients were included. The mean of LpA value was 41,08 mg/dl (standard deviation 38, range 1–155, percentile 25th: 9,7; percentile 50th: 28,8; percentile 75th: 59,1). 24,5% presented levels of LpA greater than 60 mg/dl. The percentage of patients with LpA levels &gt;60 mg was 32,4% in low SCORE group and 22,4% in greater than low SCORE group without significant differences. The table compares the LpA values according to the cardiovascular risk SCORE those patients presented before the acute coronary syndrome (low SCORE vs moderate, high or very high SCORE). As we can see in the table, we found a trend to present higher LpA values in patients with low SCORE risk compared to those with higher than low SCORE risk, without reaching statistical significance. Conclusions In a sample of young patients with acute coronary syndrome, the LpA mean was 41,08 mg/dl. 24,5% of patients had values of LpA greater than 60 mg/dl. No significant differences were found according to the SCORE prior to the event, although there was a non-significant trend towards a higher LpA in patients with low SCORE.

Se comparó la incidencia de labaéteria Hdicobacter pylori en un lugar pe baja incidencia de cáncer gástrico, Poás ( 15. 13%) y otro de incidencia muy alta, Puriscal (83. 53%) Se eligió a 185 adultos de cada cantón, similares en edad y sexo y se practicó un estudio serológico para buscar anticuerpos IgG para H. pylori, y una gastroscopía para tomar dos biopsias por caso. Los resultados no apoyan la existencia de una fuerte relación entre H. pylori y cáncer gástrico

PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients’ responses were graded according to the Miller–Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR (P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens (P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.
