Prevalence of people living with multidrug-resistant HIV and limited treatment options in Spain.

Objectives: Our aim was to determine the prevalence and characteristics of people with HIV on antiretroviral therapy (ART) with multidrug resistance (MDR; confirmed resistance to three or more [or resistance to two or more plus contraindication to one or more] core ART classes) and limited treatment options (LTOs) in Spain.

Methods: This was an observational, retrospective, multicentre, cross-sectional chart review study undertaken in five reference Spanish centres. Participants were people with HIV on ART with MDR and LTOs (detectable viral load [HIV-RNA >200 copies/mL], treatment-limiting drug-drug interaction [DDI], or intolerance precluding the use of one or more ART classes).

Communication skills in practice vs. communication in the real world: Insights from an international medical student symposium.

Objective: To explore and compare medical students' experiences with communication skills training (CST) in medical education.

Method: Five medical students from the U.S.

Identification of Lower-Limb Motor Tasks via Brain-Computer Interfaces: A Topical Overview.

Recent engineering and neuroscience applications have led to the development of brain-computer interface (BCI) systems that improve the quality of life of people with motor disabilities. In the same area, a significant number of studies have been conducted in identifying or classifying upper-limb movement intentions. On the contrary, few works have been concerned with movement intention identification for lower limbs.

Validating the Coronavirus Anxiety Scale in a Colombian sample.

The present instrumental study evaluated the psychometric properties of the with 421 Colombian adults in full lockdown of coronavirus. The reliability was excellent, obtained through the Cronbach's Alpha coefficient ( = 0.83).

A Comparison of Deep Learning Models for Detecting COVID-19 in Chest X-ray Images.

COVID-19 has spread around the world rapidly causing a pandemic. In this research, a set of Deep Learning architectures, for diagnosing the presence or not of the disease have been designed and compared; such as, a CNN with 4 incremental convolutional blocks; a VGG-19 architecture; an Inception network; and, a compact CNN model known as MobileNet. For the analysis and comparison, transfer learning techniques were used in forty-five different experiments.

Label-Free Nanoplasmonic Biosensing of Cancer Biomarkers for Clinical Diagnosis.

Biosensing of cancer biomarkers enabling early diagnosis of cancer constitutes an essential tool for clinical intervention and application of novel therapies against cancer disease. Optical biosensor instruments as point-of-care (POC) devices and operating under label-free scheme have demonstrated to provide fast, simple, and high-sensitivity assays even at home care environment. Nanoplasmonic biosensors are thought to be a powerful tool for detection of complex analytes of relevant clinical applications.

Nanoplasmonic biosensor device for the monitoring of acenocoumarol therapeutic drug in plasma.

Acenocoumarol (Sintrom®) is an oral anticoagulant prescribed for the treatment of a variety of thromboembolic disorders such as atrial fibrillation and thrombosis or embolism. It inhibits fibrin production preventing clot formation. Acenocoumarol has a narrow therapeutic range, and its effects depend on several factors, such as body weight, age, metabolism, diet, certain medical conditions or the intake of additional drugs, among others.

Accuracy of transcutaneous laryngeal ultrasound for detecting vocal cord paralysis in the immediate postoperative period after total thyroidectomy.

Background: Transcutaneous laryngeal ultrasound (TLUS) has emerged as a promising imaging tool for vocal cord examination in patients undergoing thyroid surgery. The focus of this prospective, double-blind study was to assess the accuracy of TLUS in the diagnosis of vocal cord paralysis in the immediate postoperative period following total thyroidectomy.

Methods: The study included 93 patients undergoing total thyroidectomy and assessed by videostrobolaryngoscopy (VSL) and TLUS.

The reproductive transition in an indigenous population of northern Argentina.

Latin America has been registering a fast decrease in fertility rates since the mid-twentieth century. This change can be linked to the modernization process these populations have been undergoing. However, research with Latin American indigenous populations, which are undergoing relatively similar lifestyle changes, shows very different trends in fertility.

Development of a new magnetic beads-based immunoprecipitation strategy for proteomics analysis.

Sample pre-treatment is a critical step for an efficient and reliable analysis and it is highly dependent on the complexity of the matrix. This work shows an example of application of an immunoprecipitation approach using a new magnetic beads-based format, which allows a selective/specific extraction of potential biomarkers from metastatic prostate cancer. Results obtained on the development of this method, and its application for the extraction and pre-concentration of certain biomarkers present in metastatic cell lines of prostate cancer, are presented and discussed.

LED power reduction trade-offs for ambulatory pulse oximetry.

The development of ambulatory arterial pulse oximetry is key to longer term monitoring and treatment of cardiovascular and respiratory conditions. The investigation presented in this paper will assist the designer of an ambulatory pulse oximetry monitor in minimizing the overall LED power consumption (P LED,TOT) levels by analyzing the lowest achievable limit as constrained by the optical components, circuitry implementation and final SpO2 reading accuracy required. LED duty cycle (D LED) reduction and light power (P LED,ON) minimization are proposed as methods to reduce P LED,TOT.

[Evolution of anxiety and depression detected during hospitalization in an Internal Medicine service].

Objective: To study the evolution of the symptoms of anxiety (Ax) and depression (Dp) two months after hospital release and factors associated with their persistence.

Method: An observational longitudinal study. Patients with Ax or Dp, evaluated by the Hospital Anxiety and Depression (HAD) scale on the fourth day of hospitalisation, were followed over two months without the use of psychopharmacological drugs.

Transverse myelitis following general and epidural anaesthesia in a paediatric patient.

A 13-year-old girl developed transverse myelitis 2 weeks after an uncomplicated, combined general and epidural anaesthetic for orthopaedic surgery. Since epidural anaesthesia had been used, a causal relationship might have been assumed. We review the aetiology and pathogenesis of acute transverse myelitis and the role of anaesthesia in this disorder.

[Epidural spinal cord stimulation for interstitial cystitis].

Introduction: Interstitial cystitis, a chronic inflammatory disorder of the bladder wall, is highly painful and incapacitating. Urinary frequency and urgency develop, as well as nocturia, dysuria, perineal pain and reduction of bladder capacity. The condition seems to arise from a variety of factors with multiple and diverse pathogenic mechanisms and is refractory to medical and surgical treatment.

[Isoenzymatic characterization of strains of Entamoeba histolytica isolated from Cuban patients and foreigners from Africa].

An analysis was made of the isoenzyme patterns of 61 Entamoeba histolytica strains: 42 from Cuba and 19 from Angola Mozambique and Ghana. By means of these patterns the non-pathogenic nature of the Cuban strains (Group 1) was shown. It coincided with the clinical characteristics of the infection in the carriers.
