WTP was determined using the contingent valuation method, and a two-part regression model was applied to analyze the factors influencing WTP.Results: The study included 4232 participants and discovered that approximately 17.41% were willing to pay for telemedicine services. Those aged 60 and older, employed in the government or private sector, in higher socioeconomic quintiles, and experiencing chronic health issues showed a positive association with their WTP value. Conversely, individuals aged between 30 and 44 years, married, and unemployed exhibited a negative association with a lower WTP value.Conclusion: The findings indicate that most respondents hesitated to pay for telemedicine services, with a significant influence from sociodemographic characteristics, underscoring the need to promote telemedicine use among underserved populations and address health disparities.Keywords: healthcare, sociodemographic, questionnaire, contingent valuation method

The purpose of the study was to assess the HRQoL of individuals with chronic diseases residing in the Al-Jouf region of Saudi Arabia. Furthermore, the current study also sought to ascertain the impact of multimorbidity and the duration of illness on HRQoL.Material and Methods: A cross-sectional study was conducted among the residents of Al-Jouf region for a period of 6 months. A self-administered EuroQoL (EQ-5D-5L) study tool was used. Appropriate statistical analysis was conducted to ascertain the relationship between various variables and HRQoL.Results: A total of 500 out of 562 participants completed the study, with a response rate of 88.97%. Participants had a mean age of 46.15 ± 16.79 years, and the majority were female (n = 299; 59.80%). A mean HRQoL score of 0.82 ± 0.20 was reported, poorest in patients with kidney failure (0.65 ± 0.26) and highest in hepatitis. However, nearly half of the participants had diabetes mellitus type II (n = 205, 39.20%). Patients aged < 30 years (OR: 0.109; p = 0.002), male participants (OR: 0.053; p < 0.001), no disability (OR: 0.143; p = 0.002), and < 2 comorbid diseases (0.84 ± 0.18; p < 0.001) reported better QoL. Additionally, comorbid conditions such as DM, prolong the duration of the overall illness (14.19 ± 7.67 years). Overall, imperfect health (n = 390, 78%) was reported by the study participants.Conclusion: The present study provided preliminary data about the current HRQoL status of individuals with imperfect health and lower HRQoL. In the future, large-scale longitudinal studies are required to investigate the most prevalent chronic diseases, their associations, and change in HRQoL, as there is a dearth of information in the Saudi population.Keywords: HRQoL, EQ-5D-5L, chronic diseases, diabetes mellitus, hypertension, Saudi Arabia, disease outcomes, quality of life

Our aim was to determine the level of patient satisfaction with pharmacy services and related factors at community pharmacies located in Punjab, Pakistan.Methods: A questionnaire-based cross-sectional study was conducted from May 2021 to July 2021 by administering the questionnaire to the patients using stratified random sampling method. Survey instrument comprised 4 sections including demographics, satisfaction towards provision of facilities, the provision of information, their accessibility to patients, the relationship between pharmacists and patients and the continuity of care provided. Categorical data were represented by percentages. Descriptive statistics were calculated for satisfaction scores. Simple and multiple logistic regression models were used to find the odds ratios. A p-value of less than 0.05 was considered statistically significant.Results: Response rate of the survey was 92%. Only 30% of patients agreed that the pharmacist was available for counseling on their visit. About 52% agreed that the counseling time provided by pharmacist was enough. Most of the pharmacy patients (61%) trusted the pharmacist regarding any query about medicine and were satisfied with the way the pharmacist resolved issues. Mean satisfaction score of the pharmacy patients was 45.75 with a range of 25 (highly satisfied) to 66 (highly dissatisfied).Conclusion: The provision of community pharmacy services to patients was not satisfactory. Furthermore, the absence of pharmacist in the pharmacy and the lack of provision for counseling time raised concerns.Keywords: pharmacies, pharmacists, community pharmacy services

Alruwaili NK, Zafar A, Imam SS, et al. Int J Nanomedicine. 2020;15:4717–4737. The Editor and Publisher of International Journal of Nanomedicine wish to retract the published article. Concerns were raised regarding the alleged duplication of isotonicity images in Figure 8. The corresponding author did cooperate with the investigation and images relating to the isontonicity study were provided. However, despite the authors’ assistance, it was still not clear how the images came to be duplicated, and, as we cannot verify the validity of the published work, we are therefore retracting the article. The authors have been informed and do not agree with this decision. We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.

Pharmacy, Faculty of Pharmacy (Boys), Al-Azhar University, Nasr City, Cairo, EgyptCorrespondence: Ameeduzzafar Zafar Email zzafarpharmacian@gmail.comPurpose: The present study was designed to study the gentamycin (GTM)-loaded stimulus-responsive chitosan nanoparticles to treat bacterial conjunctivitis.Methods: GTM-loaded chitosan nanoparticles (GTM-CHNPs) were prepared by ionotropic gelation method and further optimized by 3-factor and 3-level Box–Behnken design. Chitosan (A), sodium tripolyphosphate (B), and stirring speed (C) were selected as independent variables. Their effects were observed on particle size (PS as Y1), entrapment efficiency (EE as Y2), and loading capacity (LC as Y3).Results: The optimized formulation showed the particle size, entrapment efficiency, and loading capacity of 135.2± 3.24 nm, 60.18± 1.65%, and 34.19± 1.17%, respectively. The optimized gentamycin-loaded chitosan nanoparticle (GTM-CHNPopt) was further converted to the stimulus-responsive sol-gel system (using pH-sensitive carbopol 974P). GTM-CHNPopt sol-gel (NSG5) exhibited good gelling strength and sustained release (58.99± 1.28% in 12h). The corneal hydration and histopathology of excised goat cornea revealed safe to the cornea. It also exhibited significant (p< 0.05) higher ZOI than the marketed eye drop.Conclusion: The finding suggests that GTM-CHNP-based sol-gel is suitable for ocular delivery to enhance the corneal contact time and improved patient compliance.Keywords: chitosan, nanoparticles, gentamycin, histopathology, antimicrobial assessment, HET CAM test
