Protein glycosylation is a diverse and common post-translational modification that has been associated with many important roles such as protein function, including protein folding, stability, enzymatic protection, and biological recognition. N-glycans attached to glycoproteins (such as lactoferrin, lactadherin, and immunoglobulins) cannot be digested by the host and reach the large intestine, where they are consumed by certain beneficial microbes. Therefore, they are considered next-generation prebiotic compounds that can selectively stimulate the gut microbiome's beneficial microorganisms. However, the isolation of these new classes of prebiotics requires novel enzymes. Here, we describe the recombinant production of novel glycosidases from different Bifidobacteria strains (isolated from infants, rabbits, chicken, and bumblebee) for improved N-glycan isolation from glycoproteins. The method presented in this study includes the following steps molecular cloning of Bifidobacterial genes by an in vivo recombinational cloning strategy, control of transformation success, protein induction, and protein purification.

To determine the main clinical and tomographic characteristics of patients with diffuse interstitial lung disease at Trujillo Regional Teaching Hospital.

Case series. Tomographic examinations and clinical data were obtained from patients with interstitial pulmonary disease who attended the pulmonology service of Trujillo Regional Teaching Hospital. The information collected was recorded and systematized in Excel. For the statistical analysis, SPSS 23.0 program was used.

Data from 103 patients were obtained, of which 60.2% were female, and 39.8% were male. The average age was 72 years for both groups. Main clinical manifestations were cough (82.5%), dyspnea (76.7%), joint pain (43.7%), weight loss (40.8%), velcro crackles (35%) and digital clubbing (28.2%). Exposure to wood smoke was present in 46.6%, exposure to inorganic dust in 12.6% and fowl ownership in 9.7% of cases. Thirty-one (30.1%) patients presented comorbidities. Among these, rheumatic diseases and arterial hypertension were the most frequent. Non-specific interstitial pneumonia pattern was present in 26.2% of the cases; probable usual interstitial pneumonia in 16.5%; organized type in 12.6%; usual interstitial in 10.7%; acute interstitial in 2.9% and 27.1% had no defined tomographic pattern.

In the studied population, clinical and tomographic characteristics of interstitial lung parenchymal diseases are variable in magnitude and forms of presentation. Female sex and exposure to fuels were the most frequent associated factors. Connective tissue diseases could also explain study findings.

The average world population is far from reaching these habits due to the lack of access to healthy foods and a high prevalence of malnutrition. Understanding the impact of healthy sustainable food systems is growing worldwide to reach food security for the global population and future generations. A systemic perspective of this concept includes the health and well-being of individuals and the environmental, economic, socio-cultural, public policies context, besides food, agriculture, and ecological sciences. We need to confront the menaces and challenges represented by the ongoing changes of our era, which strongly generate global food insecurity. This issue is relevant not only for human health but also for climate change and other threats, based on modifications in production, handling, and consumption of foods that consider health and welfare impact at individual and planetary levels. In this review, some key concepts related to healthy and sustainable food systems are presented.Healthcare professionals make decisions in a context of uncertainty. When making a diagnosis, relevant patient characteristics are categorized to fit a particular condition that explains what the patient is experiencing. During the diagnostic process, tools such as the medical interview, physical examination, and other complementary tests support this categorization. These tools, known as diagnostic tests, allow professionals to estimate the probability of the presence or absence of the suspected medical condition. The usefulness of diagnostic tests varies for each clinical condition, and studies of accuracy (sensitivity and specificity) and diagnostic impact (impact on health outcomes) are used to evaluate them. link2 In this article, the general theoretical and practical concepts about diagnostic tests in human beings are addressed, considering their historical background, their relationship with probability theories, and their practical utility with illustrative examples.

It is required to have validated instruments in health science students that identify unhealthy habits and assess the impact of educational interventions and programs aimed at promoting a healthy lifestyle.

To evaluate the validity and reliability of an instrument to measure medical students' lifestyles.

A lifestyle questionnaire was developed using the Delphi technique by a group of experts. The final questionnaire was applied to 332 students of the School of Medicine of the Ricardo Palma University in 2017. A preliminary examination was carried out to assess preconditions for construct validityincluding the correlation matrix, the Kaiser Meyer Olkin statistic, and the Bartlett sphericity test. Factor analysis was used for construct validity, and the possible resulting factors were extracted through the principal component analysis. link3 Cronbach's alpha coefficient was calculated to assess the instrument reliability.

In this study, 41.6% of participants were men with a mean age of 20 years (standard deviation = 3). The preconditions for the factor analysis were a Kaiser Meyer Olkin coefficient = 0.773 and a significant Bartlett sphericity test. For the 47 items of the final questionnaire, the factor analysis showed an explained variance of 56.7% with eigenvalues greater than one. Cronbach's alpha was 0.78. The final questionnaire could assume values between -23 to 151 points. Based on a cut point of 71 points, the prevalence of students with an unhealthy lifestyle was 73.6%.

The developed instrument has acceptable validity and reliability to measure lifestyle in medical students. For external validation, studies in other university populations are suggested.

The objective of this study was to assess the antibacterial effectiveness of diode laser during root canal treatment in artificial models of infected periapical lesions. MATERIAL AND METHODS One hundred twenty-two extracted premolar single-rooted teeth were inserted into methyl methacrylate artificial models of periapical lesions, and bacterial solutions of Enterococcus faecalis (ATCC 29212) and Streptococcus mitis (ATCC 49456) were then applied to the models. The respective diameters of lesions in the artificial models represented 3 different subgroups based on lesion size. The laser protocol used for endodontic disinfection had a power output of 1.5 W and a wavelength of 810 nm. The impact on cell viability was evaluated by flow cytometry. RESULTS Disinfection with laser did not differ between microorganisms (P=0.137), and laser irradiation with a longer duration had better disinfecting action for both microorganisms (P.

Cardiotoxicity after cancer treatment is a potentially preventable life-threatening complication among women with breast cancer. There is no algorithm to identify women with breast cancer at risk of cardiotoxicity.

We quantified signs and symptoms as well as selected laboratory values among women with breast cancer who developed cardiotoxicity.

The clinical characteristics (n = 15) were collected from electronic health records. Spearman correlation coefficients and a nonparametric statistical test were used to analyze data.

Significant statistical differences were detected in the laboratory values comparing the first and second half of 6 months before cardiotoxicity including alanine aminotransferase (U/L) (30.67 ± 26.27 and 42.31 ± 35.65, respectively; P = .03, Cohen's d = 0.37). A negative correlation was found between estimated glomerular filtration rate and new onset of more than 1 sign or symptom (Spearman ρ = -0.5, P = .06).

Investigating clinical characteristics before cardiotoxicity may determine the mechanism(s) and identify high-risk patients, but further studies are required.

Heart failure (HF) is a multifaceted syndrome that requires self-management for adherence to treatment to control symptoms. Symptoms need to be monitored to prevent impending HF exacerbations. Few HF study authors have assessed efficacy of mobile health (mHealth) interventions particularly with virtual visits to evaluate outcomes such as symptoms and healthcare utilization.

The aim of this pilot study was to evaluate the potential effect of mHealth self-management interventions on symptom status and health-related quality of life and describe health care utilization in patients with HF.

This 3-month pilot study included 74 patients with HF and used a randomized 3-group repeated-measures design (enhanced usual care, mHealth, and mHealth plus [+] virtual visits). Surveys included the Heart Failure Symptom Survey, EuroQol, and a specialized phone application for patients to report weights and medications.

The mHealth groups had an overall decrease in most symptom severity and frequency, particularly shortness of breath. Compared to enhanced usual care, both the mHealth+ and mHealth groups showed promise with medium effect sizes (range .55-.60) in relation to shortness of breath and a medium effect (.51) for lower extremity edema for the mHealth+ group. There was a trend toward improvement in health-related quality of life in both intervention groups at month 3. The mHealth+ group had fewer rehospitalizations.

In general, both mHealth groups fared better on symptoms and health care utilization. Small to medium effect sizes on selected symptom outcomes warrant this study to be conducted in a fully powered study. Virtual visits may assist in symptom recognition and self-management.
