Background: Despite the negative consequence of the unmet need for family planning no study has been conducted on women working in the industrial parks. Therefore this study aimed to determine the prevalence of unmet need for family planning and its associated factors among women in reproductive age working in Hawassa industrial park. Methods: An institution-based cross-sectional study was conducted from July 1 to 30/2021 among randomly selected 405 women working in Hawassa industrial park. Data was collected using face-to-face interviews using a pre-tested structured questionnaire. The data was entered into Epi-data 3.1 and exported to SPSS Version 24 for statistical analysis. Bivariable and multivariable logistic regression analyses were used to identify factors associated with the unmet needs for family planning. Independent factors associated with the unmet need for family planning were assessed using AOR with their corresponding 95% CIs at P-value < 0.05 cut of point. Result: In this study, the prevalence of unmet need for family planning was 27.7% (95% CI 23.2 to 32.3). Educational status [AOR = 4.53; CI (1.62, −12.61)], marital status (AOR = 7.2; 95% CI: (3.77, 13.73)], residence [AOR = 0.56; 95% CI: (0.31, 0.99)], and knowledge of family planning [AOR = 0.36; 95% CI: (0.20, 0.63)] were independent predictors of unmet need for family planning. Conclusion: This study found that the prevalence of unmet needs for family planning was high. Educational status, marital status, residence, and knowledge of family planning were significantly associated with unmet needs of family planning.

Although the production of carboxymethylcellulose from different raw materials is commercial, its preparation from agro-industrial residues has still been poorly explored in terms of performance, cost-effectiveness, and sustainability. Here, sugarcane bagasse was used as raw material for the carboxymethylcellulose (CMCb) synthesis within the biorefinery context. Sequential treatments were used for the removal of hemicellulose and lignin and the isolation of cellulose, whose conversion into CMCb was carried out through treatments with NaOH and monochloroacetic acid (MCA). The chemical modifications led to a CMCb with a substitution degree of 0.44, purity of 71.3 %, and 32 % crystallinity. Our residue-based CMCb was adequate for microorganism encapsulation, a high-value application, promoting viable conidia after 5 months of storage in equivalent conditions of high-purity, commercial CMC. Our findings show a route for the preparation of valuable polysaccharides from waste in future biorefineries, which, depending on their characteristics, can be applied in different processes. Here we use them for the encapsulation of a bioagent, although they can easily be used in other applications such as packaging and coating., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Objectives: To evaluate seroconverted asymptomatic COVID-19 in pediatric Autoimmune Rheumatic Diseases (ARDs) patients and to identify the risk factors related to contagion., Methods: A cross-sectional study was conducted in March 2021, before vaccination of children and adolescents in Brazil, including 77 pediatric ARDs patients, followed at a tertiary hospital and 45 healthy controls, all of them without a previous diagnosis of COVID-19. Data was obtained by a questionnaire with demographic data, symptoms compatible with COVID-19 over the previous year, and contact with people with confirmed COVID-19. Patient's medical records were reviewed to access data regarding disease and current medications. A qualitative immunochromatographic SARS-CoV-2 test was performed on all participants., Results: Patients and controls were similar in terms of female gender (70.1% vs. 57.8%, p = 0.173), age (14 vs. 13 years, p = 0.269) and SARS-CoV-2 positive serology (22% vs. 15.5%, p = 0.481). 80.5% of rheumatic patients were in use of immunosuppressive drugs: 27.3% of them used corticosteroids (33.3% in high doses), and 7.8% on immunobiologicals. No statistical differences were found between positive (n = 17) and negative serology (n = 60) patients regarding demographic/socioeconomic data, contact with people with confirmed COVID-19, use and number of immunosuppressive drugs, use and dose of corticosteroids, use of hydroxychloroquine and immunobiological drugs (p > 0.05)., Conclusions: Pediatric rheumatic disease patients were infected at the same rate as healthy ones. Neither the underlying pathology nor its immunosuppressive treatment seemed to interfere with contagion risk., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2022 HCFMUSP.

Objective: To analyze major histocompatibility complex expression in the muscle fibers of juvenile and adult dermatomyositis., Method: In total, 28 untreated adult dermatomyositis patients, 28 juvenile dermatomyositis patients (Bohan and Peter's criteria) and a control group consisting of four dystrophic and five Pompe's disease patients were analyzed. Routine histological and immunohistochemical (major histocompatibility complex I and II, StreptoABComplex/HRP, Dakopatts) analyses were performed on serial frozen muscle sections. Inflammatory cells, fiber damage, perifascicular atrophy and increased connective tissue were analyzed relative to the expression of major histocompatibility complexes I and II, which were assessed as negatively or positively stained fibers in 10 fields (200X)., Results: The mean ages at disease onset were 42.0±15.9 and 7.3±3.4 years in adult and juvenile dermatomyositis, respectively, and the symptom durations before muscle biopsy were similar in both groups. No significant differences were observed regarding gender, ethnicity and frequency of organ involvement, except for higher creatine kinase and lactate dehydrogenase levels in adult dermatomyositis (p<0.050). Moreover, a significantly higher frequency of major histocompatibility complex I (96.4% vs. 50.0%, p<0.001) compared with major histocompatibility complex II expression (14.3% vs. 53.6%, p=0.004) was observed in juvenile dermatomyositis. Fiber damage (p=0.006) and increased connective tissue (p<0.001) were significantly higher in adult dermatomyositis compared with the presence of perifascicular atrophy (p<0.001). The results of the histochemical and histological data did not correlate with the demographic data or with the clinical and laboratory features., Conclusion: The overexpression of major histocompatibility complex I was an important finding for the diagnosis of both groups, particularly for juvenile dermatomyositis, whereas there was lower levels of expression of major histocompatibility complex II than major histocompatibility complex I. This finding was particularly apparent in juvenile dermatomyositis.

There has been an increasing recognition of adverse short-, mid-, or long-term effects associated with the treatment as well as the disease itself that impair the health-related quality of life and functional capacity of children and adolescents with rheumatic diseases. Interestingly, cumulative evidence has suggested that exercise training may benefit patients with juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, juvenile dermatomyositis and juvenile fibromyalgia, attenuating several clinical symptoms related to physical disability. Remarkably, recent evidence also suggests that exercise may have direct effects on the pathogenesis of autoimmune diseases by attenuating chronic low-grade systemic inflammation. It is also important to emphasize that no exercise-related adverse effects have been reported. This short review provides the evidence for physical training as a treatment of pediatric rheumatic diseases, introducing a novel concept that exercise is a treatment for these populations., (Copyright 2010 Elsevier B.V.

Background: Patients with fixed orthodontic appliances often experience an absolute increase in the number of Streptococci mutans colony-forming units (cfu). The aim of this investigation was to study the development of biofilm and S. mutans cfu in connection with stainless steel ligatures and elastomeric rings in orthodontic patients treated with and without 0.4% stannous fluoride gel (SFG)., Material: Forty-seven patients were divided into 2 groups: those treated with 0.4% SFG for 4 minutes (experimental) and those without 0.4% SFG (control). In each patient, elastomeric rings were used for ligation on 1 side of the dental arch midline, and stainless steel ligatures were used on the opposite side. Saliva samples were collected before and after appliance placement. At 15 and 30 days after appliance placement, biofilm samples from the stainless steel ligatures and the elastomeric rings were collected and subjected to microbiologic procedures and scanning electron microscopy (SEM) analysis., Results: The numbers of S. mutans cfu in the saliva and biofilm were not statistically different between the teeth fitted with elastomeric rings and stainless steel ligatures, or between the experimental and control groups. SEM analysis showed biofilm formation on both ligature ties., Conclusions: Topical application of 0.4% SFG in orthodontic patients with elastomeric rings or stainless steel ligatures does not cause a significant decrease in S. mutans cfu in the saliva and biofilm.
