Low phospholipid-associated cholelithiasis syndrome (LPAC), a not uncommon cause of biliary problems and hospital admissions.

BACKGROUND AND AIMS: Biliary diseases are a major source of morbidity and mortality for patients and a burden for the healthcare system. The genetic syndrome LPAC (low phospholipid-associated cholelithiasis) is a little known and rare entity whose treatment with bile salts avoids symptoms, admissions and the need for surgery. Our aim is to determine its incidence and characteristics in our center. METHODS: Prospective study between February 2021 and September 2022. LPAC was diagnosed if (at least two): onset of biliary problems <40 years of age, recurrence of symptoms after cholecystectomy, ultrasound image of hepatolithiasis (multiple echoic foci, comet-tail images, hepatolithiasis with acoustic shadow). Demographic, clinical, genetic (analysis of MDR3 gene mutations) and ultrasound characteristics were analyzed, as well as their incidence in hospital admissions for biliary causes. RESULTS: 36 patients with LPAC were identified. Of these, 6 were among 237 admissions for biliary causes in the previous 9 months, with an incidence of 2.5% (95%CI 1.17-5.41). By age subgroup, the incidence was 16.7% in those admitted <40 years and 9.1% in those <50 years. Considering women only, the incidence was 21% in those admitted <40 years and 15.8% in those <50 years. All patients remained asymptomatic after treatment with ursodeoxycholic acid and there were no new admissions. CONCLUSIONS: LPAC syndrome is not as uncommon as it may appear, especially in women <50 years of age admitted with biliary problems. Its correct diagnosis based on simple criteria would avoid a significant number of hospital admissions and unnecessary cholecystectomies.

A Portable Dynamic Laser Speckle System for Sensing Long-Term Changes Caused by Treatments in Painting Conservation.

Dynamic laser speckle (DLS) is used as a reliable sensor of activity for all types of materials. Traditional applications are based on high-rate captures (usually greater than 10 frames-per-second, fps). Even for drying processes in conservation treatments, where there is a high level of activity in the first moments after the application and slower activity after some minutes or hours, the process is based on the acquisition of images at a time rate that is the same in moments of high and low activity. In this work, we present an alternative approach to track the drying process of protective layers and other painting conservation processes that take a long time to reduce their levels of activity. We illuminate, using three different wavelength lasers, a temporary protector (cyclododecane) and a varnish, and monitor them using a low fps rate during long-term drying. The results are compared to the traditional method. This work also presents a monitoring method that uses portable equipment. The results present the feasibility of using the portable device and show the improved sensitivity of the dynamic laser speckle when sensing the long-term process for drying cyclododecane and varnish in conservation.

Study of humoral and cellular immunity in vaccinated with mRNA-1273.

The new vaccines against SARS-CoV-2 have raised a lot of expectations about their ability to induce immunity and the duration of this. This is the case of mRNA vaccines such as Moderna's mRNA-1273. Therefore, it is necessary to study the humoral and cellular immunity generated by these vaccines. Our objectives are determining what is the normal response of antibody production, and what is the level of protective antibodies and monitoring patients in case of subsequent infection with COVID-19. We present the first results of a longitudinal study of the humoral response in 601 health workers vaccinated with Moderna. The results show a humoral immunity at 90 days after the second dose of 100%, with a strong decrease between the levels of circulating anti-S IgG antibodies between days 30 and 90 post-vaccination. Observing a steeper decline in those who had higher titles at the beginning. In addition, we present a cellular response of 86% at three months after the second dose, which is related to low humoral response.

Appropriate Self-Perceived Behaviors in Primary Education Pupils During Sports Games.

Based on the results obtained from primary education students-fifth and sixth graders-the aim of this work is to check the appropriate self-perceived behaviors during and at the end of the game. The study population was made up of 698 students from fifth and sixth grade in the Autonomous Region of Castilla-La Mancha (Spain). Data were collected through a questionnaire (scale) on the social skills of primary school students linked to the adequate skills when losing, the adequate skills when winning, and the adequate skills during the game. Study results revealed that analyzed behaviors vary, depending on the moment of the game, being it more frequently during the development of the game than when losing or winning.

The Effects of an Appropriate Behavior Program on Elementary School Children Social Skills Development in Physical Education.

The purpose of this study was to see the effects of an appropriate behavior development program in relation to the improvement of fair play and social skills behaviors of elementary school children during the physical education class. The participants of this study were 204 students from 5th and 6th grade from seven different public schools in Castilla-La Mancha, Spain. Data was collected through a questionnaire to measure students' pre and post appropriate behaviors when winning, appropriate behaviors when loosing, appropriate behaviors during the game, fair play skills and social skills, during the physical education class. Results from this study revealed that participants improved their behaviors with the implementation of the intervention (appropriate behavior program), generating positive changes in students' attitudes and social skills during physical education class. In relation to children gender, girls had better scores than boys in relation to appropriate behaviors when losing. Further, when comparing students' age, those from 10 to 11 years old scored higher in fair play behaviors and social skills. In conclusion, the intervention program was effective to improve the behaviors of the school children, generating positive changes in their attitudes and social skills during physical education.
