  • Cardiovascular comorbidity is common in individuals with chronic obstructive pulmonary disease (COPD). This factor interferes with pharmacological treatment. The use of β-blockers has been proposed for their known cardioprotective effects. However, due to their adverse reactions, and the risk of causing bronchospasm, there is reluctance to use them. To summarize existing evidence on the effects of β-blocker use in COPD associated with cardiovascular comorbidities in relation to disease severity, exacerbation, and mortality outcomes. EMBASE, Medline, Lilacs, Cochrane Library, and Science Direct databases were used. Observational studies that evaluated the effects of β-blockers on individuals with COPD and cardiovascular comorbidities, and related disease severity, exacerbations, or mortality outcomes were included. Studies that did not present important information about the sample and pharmacological treatment were excluded. Twenty studies were included. Relevance to patient care and clinical practice: The use of β-blockers in individuals with COPD and cardiovascular disease caused positive effects on mortality and exacerbations outcomes, compared with the results of individuals who did not use them. The severity of the disease caused a slight change in forced expiratory volume in 1 second. The odds ratio for mortality was 0.50 (95% confidence interval [CI], 0.39 to 0.63; p<0.00001), and for exacerbations, 0.76 (95% CI, 0.62 to 0.92; p=0.005), being favorable to the group that used β-blockers. Further studies are needed to study the effect of using a specific β-blocker in COPD associated with a specific cardiovascular comorbidity.

  • Purpose : This study aimed to carry out a scoping review to investigate the research trends in non-pharmacological interventions for physical rehabilitation following breast cancer treatment. Methods : A scoping review was conducted according to the five steps outlined by Arksey and O'Malley and PRISMA-ScR. We searched three domestic databases (ScienceOn, Riss, KCI) and two international databases (PubMed, Cochrane Central) between January 2014 and April 2024. The keywords used were 'breast cancer surgery', 'breast cancer treatment', 'breast cancer lymphedema', 'intervention', 'management', 'therapy', 'disorder', and 'dysfunction'. Results : In terms of publication, the number of studies in the past five years has increased compared to the previous five years, with most studies focusing on patients aged 41 to 60 and who underwent surgical treatment for breast cancer. A total of 43 different types of non-pharmacological interventions were applied: 21 single interventions and 22 combination interventions. Among the intervention methods, complete decongestive treatment (CDT), resistance training, and manual lymphatic drainage were the most frequently utilized. The most common duration of intervention turned out to be 4~5 weeks and more than 8 weeks, with frequencies of 2~3 sessions per week and more than 4 sessions per week. The most frequently used dependent variables included range of motion (ROM) and disabilities of the arm, shoulder and hand (DASH) for the function and disorder of the upper limb category; arm circumference or volume and bio-impedance for the lymphedema category; visual analogue scale (VAS) and numerical rating scale (NRS) for the pain category; and the European organization for research and treatment of cancer quality of life questionnaire breast cancer module (EORTC QLQ) and functional assessment of cancer therapy-breast (FACT-B) for the quality of life category. Conclusion : The findings of this scoping review provide valuable mapping data for non-pharmacological interventions for physical rehabilitation following breast cancer treatment. We recommend further research, particularly systematic reviews and meta-analyses, to build upon these findings.

  • This study aimed to assess the colorizing properties of bacterial cellulose (BC) using plant-based dyes, namely spinach, beet, and banana peel, and determine the dyeing conditions of each dye based on color strength (K/S) values. Tannic acid and walnut shell powder were utilized as bio-mordants, and their effects on the dyeability of BC were compared to metallic mordants. Additionally, the type of mordant and the mordanting method were assessed according to their rubbing fastness and dry-cleaning fastness. The K/S values of the colorized and mordanted BCs were also compared to examine their mordanting conditions. Finally, the mordanting conditions for spinach, beet, and banana peel dyeing were selected as post-mordanting with tannic acid, meta-mordanting with tannic acid, and post-mordanting with walnut shell powder, respectively. Based on the results, the selected mordanting conditions improved both rubbing fastness and dry-cleaning fastness of BCs to grade 5, and the light fastness achieved grade 4-5. The tensile strength and flexibility of the dyed BCs were also enhanced and comparable to that of untreated cowhide leather.

  • In the biopharmaceutical contract manufacturing organization (CMO) business, establishing a production schedule that satisfies the due date for various customer orders is crucial for competitiveness. In a CMO process, each order consists of multiple batches that can be allocated to multiple production lines in small batch units for parallel production. This study proposes a meta-heuristic algorithm to establish a scheduling plan that minimizes the total delivery delay of orders in a CMO process with identical parallel machine. Inspired by biological evolution, the proposed algorithm generates random data structures similar to chromosomes to solve specific problems and effectively explores various solutions through operations such as crossover and mutation. Based on real-world data provided by a domestic CMO company, computer experiments were conducted to verify that the proposed algorithm produces superior scheduling plans compared to expert algorithms used by the company and commercial optimization packages, within a reasonable computation time.

  • Background and Objectives: As per the available data, 75% peri and postmenopausal women experience hot flashes having negative effect on their quality of life. Using herbal medicines are stepping forward to alleviate hot flashes as the available hormonal medications have been reported the presence of side effects. This study was planned with the intention to investigate the effect of Asparagus racemosus root in the treatment of postmenopausal hot flashes in comparison to the placebo. Methods: This prospective patient blinded clinical trial randomly assigned 40 postmenopausal women with symptoms of hot flashes to receive either test drug (n=20) comprising Asparagus racemosus tablet of 1g in the dosage of 2 tablet thrice in a day for the duration of 60 days continuously or to receive placebo tablet prepared from roasted wheat flour in the same dosage and duration as test drug. The efficacy was determined by reduction in the frequency and intensity of hot flashes assessed by daily diary along with the improvement in quality of life assessed through Hot Flash-Related Daily Interference Scale. Statistical analysis was accomplished by student t test and Chi-square/Fisher Exact test. Results: Test drug significantly (p <0.001) reduced the intensity and frequency of hot flashes as well as improved the quality of life without showing any side effect. Discussion & Conclusion: According to Unani scriptures, the treatment is to treat the underlying cause, such as aberrant temperament and psychological and environmental issues. Unani drugs have emmenagogue, anti-inflammatory, analgesic, and neuroprotective qualities that can help alleviate premenstrual symptoms. Unani herbs such as C. sativus, Vitex, agnus castus, P. vulgare, N. Jatamansi, M. officinalis, and Z. officinalis have been clinically demonstrated to be effective in PMS. Thus, traditional knowledge authentication and conservation are vital for future research and appreciated for application in the modern day. Furthermore, randomised controlled trials, comprehensive reviews, and meta-analyses are suggested.

  • The growth of mobile devices and network infrastructure has brought significant changes to the music industry. Online streaming services has allowed music consumption without constraints of time and space, leading to increased consumer engagement in music creation and sharing activities, resulting in a vast accumulation of music data. In this study, we define metadata as "song sentences" by using a user's playlist. To calculate similarity, we embedded them into a high-dimensional vector space using skip-gram with negative sampling algorithm. Performance eva luation results indicated that the recommended music algorithm, utilizing singers, genres, composers, lyricists, arrangers, eras, seasons, emotions, and tag lists, exhibited the highest performance. Unlike conventional recommendation methods based on users' behavioral data, our approach relies on the inherent information of the tracks themselves, potentially addressing the cold start problem and minimizing filter bubble phenomena, thus providing a more convenient music listening experience.

  • Background: Nearly half of patients diagnosed with cancer are in the middle of their traditional working age. The return to work after cancer entails challenges because of the cancer or treatments and associated with the workplace. The study aimed at providing more insight into the occupational outcomes encountered by workers with cancer and to provide interventions, programs, and practices to support their return to work. Methods: A scoping review was conducted using the Arksey and O'Malley framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for scoping review guidelines. Relevant studies were systematically searched in PubMed/MEDLINE, SCOPUS and Grey literature from 01 January 2000 to 22 February 2024. Results: The literature search generated 3,017 articles; 53 studies were considered eligible for this review. Most of the studies were longitudinal and conducted in Europe. Three macroarea were identified: studies on the impact of cancer on workers in terms of sick leave, employment, return to work, etc.; studies reporting wider issues that may affect workers, such as the compatibility of treatment and work and employment; studies reporting interventions or policies aiming to promote the return to work. Conclusion: There is a lack in the literature in defining multidisciplinary interventions combining physical, psycho-behavioural, educational, and vocational components that could increase the return-to-work rates. Future studies should focus on interdisciplinary return to work efforts with multiple stakeholders with the involvement of an interdisciplinary teamwork (healthcare workers and employers) to combine these multidisciplinary interventions at the beginning of sick leave period.

  • Geochemical data of soil and water samples were presented in order to assess the environmental impart for drinking water sites. Microscopic observation of rock samples and physical and chemical analysis of soil and water samples were undertaken. The geology of study areas are classified into three groups such as granitic rocks, meta-sedimentary rocks and sedimentary rocks. Enrichment of heavy metals derived from those rocks is not found in this study areas. Soils were analyzed for Cu, Pb, Zn, Cd and Cr using AAS extracted by HNO$_3$+HClO$_4$ and 0.1 N HCl. Heavy metal concentrations in soils are within the range of those in uncontaminated soils. In comparison of metal contents extracted by 0.1 N HCl and HNO$_3$+HC1O$_4$, less than 10% of the heavy metals are present in the exchangeable fraction. In particular, an pollution index has been proposed to assess the degree of soil contamination. Pollution index in soils are between 0.03 and 0.47 therefore, soils are not polluted with heavy metals. Deep groundwaters within granitic rocks have been evolved into Na$\^$+/-HCO$_3$$\^$-/ type, whereas other deep groundwaters evolved into Ca$\^$2+/-HCO$_3$$\^$-/ type. The predominance of Na$\^$+/ over Ca$\^$2+/ in deep groundwaters within granitic rocks is a result of dissolution of plagioclase, but for sedimentary and meta-sedimentary rocks, dissolution of calcite is a dominant factor for their hydrogeochemistry. The pH, conductivity and contents of the most dissolved ions in the water increase with depth. Shallow groundwaters, however, are highly susceptible to pollution owing to agricultural activities, considering the fact that high contents of nitrate, chloride and potassium, and high K/Na ratio are observed in some shallow groundwaters. In a thermodynamic approach, most natural water samples are plotted within the stability fields of kaolinite and smectite. Therefore, microcline and other feldspars will alter to form clay minerals, such as kaolinite and smectite. From the modelling for water-rock interactions based on mass balance equation, models accord well with behavior of the ions and results of thermodynamic studies are derived.
