In this paper we propose a new distribution of Gaussian points to compute the weak form integrals of the Generalized Finite Element Method (GFEM). The relevance of this new distribution is the ...possibility of evaluating the integrals of oscillatory functions inside the reference triangle in an alternate way. A simple scheme of relocation of the quadrature points allows to improve the efficacy of the method. A wave propagation problem is solved with the proposed technique and its performance is compared to conventional and other existing proposals. In addition, we propose a new distribution of Gaussian points to the tetrahedral reference element
Introduction: Multisensory intervention for preterm babies is developmentally appropriate and has the capacity to integrate information from different senses-Auditory, Tactile, Visual, and Vestibular ...(ATVV). Involving mothers in the intervention may help mimic the preterm babies’ intrauterine environment. Mothers need to be systematically and effectively guided through the ATVV intervention. Before implementing the practice, it is important to ensure that mothers are sensitised with the necessary knowledge about multisensory intervention. Hence, assessing mothers’ knowledge of multisensory intervention is a significant step preceding any intervention. Aim: To assess the knowledge of multisensory intervention among mothers of preterm babies with the intention of preparing an educational package on multisensory intervention. Materials and Methods: A cross-sectional study was conducted among mothers of preterm babies admitted to the Neonatal Intensive Care Unit (NICU) of a selected hospital in Mangaluru, Karnataka, India. A total of 97 mothers were selected using a simple random sampling technique. Data on mothers’ knowledge were gathered using a proforma on baseline characteristics and a structured knowledge questionnaire on multisensory intervention for preterm babies. The data were analysed using descriptive and inferential statistics. Results: The overall knowledge scores of mothers on multisensory intervention showed a mean±SD of 7.42±2.06 with a mean percentage of 24.74%. Most mothers, 91 (93.8%), had inadequate knowledge, and 6 (6.2%) had moderate knowledge. The area-wise knowledge score of mothers revealed that in the concept of multisensory intervention, the mean±SD was 1.93±0.89 with a mean percentage of 38.56%. In the components of multisensory intervention, the mean±SD was 2.20±1.18 with a mean percentage of 24.40%. In understanding preterm babies’ behaviour, the mean±SD was 2.67±1.15 with a mean percentage of 29.67%. In aspects of practice in multisensory intervention, the mean±SD was 0.63±0.69 with a mean percentage of 8.98%. This indicates that most mothers had inadequate knowledge in the areas of multisensory intervention. A significant association between knowledge scores and the sex of the preterm babies was found (p-value=0.03). Conclusion: Most mothers had inadequate knowledge on multisensory intervention. Consequently, an educational package was developed, which included a video on multisensory intervention for preterm neonates and a handout to help mothers acquire knowledge and guide their practice.

The aim of this study was to evaluate the aesthetic results of lipoabdominoplasty in overweight patients (body mass index, 25 to 29.9) compared with normal weight patients (body mass index, 18.5 to ...24.9).
The authors performed a retrospective and comparative analysis of late follow-up results after lipoabdominoplasty performed from 2000 to 2009 in two groups of 30 patients, one with a body mass index of 25 to 29.9 and one with a body mass index of 18 to 24.9. Aesthetic results were evaluated using a scale with five objective parameters, developed in the Faculty of Medicine, University of São Paulo. There were seven evaluators: three plastic surgeons, three nondoctors, and the surgeon performing the procedure.
For all evaluators, the postoperative average grade was significantly higher than before surgery for the entire group of patients (n=60) and in each subgroup. The average grades for the normal weight group were consistently significantly higher than for the overweight group, both preoperatively and postoperatively, for all evaluators. However, the mean difference between the preoperative and postoperative grades, which measures the aesthetic improvement provided by the operation, was higher in the overweight group. Postoperatively, the average grade of the surgeon was significantly higher than for all other evaluator groups.
The normal weight group showed superior grades, both before and after lipoabdominoplasty, for all evaluators. However, the gain between preoperative and postoperative grades was higher in the overweight patient group, indicating that lipoabdominoplasty was beneficial even in these cases.

This paper proposes a new reconfiguration heuristic in order to reduce the total power loss and the maximum current of electrical radial networks. It is based on the branch-and-bound strategy, which ...is an implicit enumeration method that uses a tree structure and bounds to organize the searching process. The search tree in this paper is constructed by subdividing the feasible set using the branch-exchange technique in the networks. The constraints and the Pareto dominance are responsible for pruning the search tree. The heuristic also returns a feasible switching plan for each solution. The algorithm was successfully applied to medium- and large-scale problems.

Traditional abdominal plastic surgery results in a high rate of morbidity because of the necessity for a large undermining of the flap. In 2001, Saldanha, using the term "lipoabdominoplasty" for the ...first time, standardized a selective undermining, corresponding to 30% of the traditional undermining, between the medial borders of the rectus abdominal muscles. This procedure combines 2 traditional techniques, abdominoplasty and liposuction.
Concerns about the increasing impact of severe COVID-19 in younger individuals in Brazil came after a recent synchronised country-wide wave of cases in Brazil. This communication analyses how ...hospitalisations due to COVID-19 changed in the age groups 18–49 years and ≥70 years.
Longitudinal study based on secondary data.
Data from SIVEP-Gripe, a public and open-access database of Severe Acute Respiratory Illness records (including COVID-19 notifications), were used in this study. Statistical control charts examined changes in the magnitude and variation of younger (18–49 years) and older (≥70 years) adults who were hospitalised between 15th March 2020 and 19th June 2021.
During the few first weeks of the pandemic in Brazil, the number of COVID-19 hospitalisations increased in older adults but decreased in younger adults. Subsequently, hospitalisations reached statistical control zones in epidemiological weeks (EW) 19–48 of 2020 (EW 19-48/2020) and EW 03-05/2021 (18–49 y, mean = 26.1%; ≥70 y, mean = 32.8%). Between EW 49/2020 and EW 02/2021, the number of hospitalisations of younger adults dropped to levels below the lower control limit. In contrast, the number of hospitalisations of older adults surpassed the upper limit of the corresponding statistical control zones. However, from EW 06/2021, numbers of hospitalisations changed from statistical control zones, with hospitalisations of younger adults increasing and reaching 44.9% in EW 24/2021 and hospitalisations of older adults decreasing until EW 19/2021 (14.1%) and reaching 17.3% in EW 24/2021.
An increasing number of COVID-19 hospitalisations were observed in younger adults from EW 06/2021. This could be a result of the successful vaccination programme in older adults, who were initially prioritised, and possibly an increased exposure to highly transmissible variants of COVID-19 in younger adults who had to go to work in the absence of social protection (i.e. government financial support). Potential consequences of COVID-19 hospitalisations in younger adults could include a reduced life expectancy of the population and an increased number of people unable to perform daily activities due to post-COVID-19 conditions.
Abstract In this paper, a new methodology is applied to optimize the geometry of conductors of overhead transmission lines (TL) with high precision and low computational cost. This methodology is ...based on the sensitivity analysis of the electrical charge of the transmission lines using the adjoint method. This information is used with the gradient method and the golden section algorithm to minimize the electric field at the ground level of three-phase TL with two cables per phase. The approximation using central finite differences to obtain sensitivity is adopted for validation and comparisons. The TL's with high surge impedance loading is obtained after the optimization process.
