Graphical Abstract Highlights  Naproxen solid lipid nanoparticles (Nap-SLN) can successfully be prepared by ultrasonication  Properties of these nanoparticles can be optimized by lipid concentrations  HLB of the surfactants played a crucial effect on properties of solid lipid nanoparticles  Nap-SLN increased the drug concentration in skin layer rather than systemic absorption Accepted Manuscript AbstractThe aim of the current investigation was to produce naproxen solid lipid nanoparticles (Nap-SLNs) by the ultrasonication method to improve its skin permeation and also to investigate the influence of Hydrophilic-lipophilic balance (HLB) changes on nanoparticles properties. The properties of obtained SLNs loaded with naproxen were characterized by photon correlation spectroscopy (PCS), transmission electron microscopy (TEM) and differential scanning calorimetry (DSC). FT-IR was also used to investigate any interaction between naproxen and the excipients used at the molecular level during the preparation of the SLNs. The performance of the formulations was investigated in terms of skin permeation and also the retention of the drug by the skin. It was found that generally, with increasing the lipid concentration, the average particle size and polydispersity index (PDI) ...

Objectives: The aim of this study was to evaluate parents' perception of the oral health-related quality of life (OHRQoL) of autistic children in Iran, and to determine the quality of life of their families in relation to child' oral health status. Study design: 70 families with at least one child with autism, and 70 families with normal children were enrolled. Parents' perceptions of the OHRQoL of children were assessed using pre-validated PedsQL oral health scale questionnaire. PedsQL Family Impact Module questionnaire was also used to evaluate the impact of having an autistic child on the quality of life of their families. Both of the questionnaires were filled by parents. Parents of children with autism spectrum filled a separate questionnaire for the sibling of the autistic child. In the control families, child-reported PedsQL oral health scale questionnaire was also filled by the child himself/herself. Mann-Whitney U-test, and chi-square were used for statistical analysis. Results: There was a significant difference in the mean total score of PedsQL oral health scale questionnaire between autistics and controls. Parents of normal children reported more oral problems (p<0.001). There was not a significant difference in the mean total score of PedsQL Family Impact Module questionnaire between the families of autistics and controls in the last 7 and 30 days. Conclusion: According to parents' point of view, oral health-related quality of life of autistic children was better than normal children. However, parents of autistic children had more problems in the social and communication issues.

Background Numerous changes occur in different aspects of women’s lives in the postpartum period. Women’s adjusting with problems and taking advantage of this opportunity can develop their personality. In this regard, accurate knowledge of their experiences and feelings is necessary to help them to benefit from this period. Therefore, the present study aimed to explore the experiences related to postpartum changes in women. Methods In the present qualitative study, 23 participants, including women of childbearing age who gave birth and healthcare providers (midwives and obstetricians) in Isfahan, Iran were selected using purposive sampling with a maximum variation strategy. Data were collected through in-depth semi structured interviews, field notes, and daily notes, and simultaneously analyzed using the conventional qualitative content analysis. Results The data analysis results led to the extraction of three main categories including “feeling of decreased female attractiveness” (with two sub-categories of “ feeling of decreased beauty” and “feeling of decreased sexual function”), “feeling of insolvency and helplessness” (with two sub-categories of “physical burnout”, and “mental preoccupations”) and “beginning a new period in life” (with three sub-categories of “changing the meaning of life”, “feeling of maturity” and “deepening the communication”). Conclusions Findings of this study can provide a good context for designing interventions to improve the women’s quality of life by explaining and highlighting their experiences in the postpartum period. In this regard, providing sufficient empathy, social and psychological support from family members (especially husband), performing appropriate educational interventions and also regular assessment of women’s psychological state by healthcare providers in postpartum period can reduce their concerns and help to improve their health.

Background The transition to motherhood is associated with stress because of extensive and rapid changes to which women need to be able to adjust. To help women adjust to postpartum changes, their needs during this period must be identified. Therefore, the present qualitative study explored the needs of women for adjusting to postpartum changes. Methods In this study, 29 participants were selected through purposive sampling with maximum variation in Isfahan, Iran. Data was collected through in-depth individual interviews, daily notes, and field notes, and analyzed using conventional qualitative content analysis. Results Data analysis led to the emergence of 5 main categories: “the need to receive social support,” “the need to receive a sense of worth from the husband,” “the need to compensate and improve the situation,” “the need to create socio-cultural changes,” and “the need for training.” Conclusions According to the results of the study, in order to adjust to the changes in the postpartum period, and in addition to their efforts to compensate and improve the situation, women need to be supported by their husbands, family members and acquaintances, healthcare team, and society in various dimensions. Moreover, they should receive the information they need to turn the challenges of this period into an opportunity for growth.
