RESUMO
Aim and Objective: This study was intended to compare and determine the potency of strontium-doped nano-hydroxyapatite paste against a topical cream containing casein phosphopeptide-amorphous calcium phosphate and a regular dentifrice for remineralization of white spot lesions of enamel following orthodontic debonding. Methods: Ninety individuals with white spot lesions on their enamel who visited the orthodontic department for de-bonding were selected for the research. Patients were randomly assigned to three distinct groups with each group consisting of 30 patients. Group 1 served as the control and received regular dentifrice, Group 2 received strontium-doped nano-hydroxyapatite paste, and Group 3 received casein phosphopeptide-amorphous calcium phosphate topical cream. Patients were instructed to locally apply a specified amount of the prescribed preparation twice daily for six weeks. The data were analysed using the statistical programme SPSS 22.0 (SPSS Inc., Chicago, IL, USA), and the level of significance had been set at p < 0.05. Results: Group 1 did not show any change in the enamel following the application of toothpaste. Both Group 2 and 3 demonstrated higher post-treatment scores, indicating effective remineralization potential (p < 0.001). However, Group 2 (strontium-doped nano-hydroxyapatite paste) displayed significantly greater remineralization capacity when compared to group 3 (casein phosphopeptide-amorphous calcium phosphate topical cream). Conclusion: Compared to conventional dentifrice and casein phosphopeptide-amorphous calcium phosphate paste, strontium-doped nano-hydroxyapatite preparation demonstrated greater enamel remineralization of the white spot lesions and favourable surface alterations in the enamel surface. strontium-doped nano-hydroxyapatite can be utilised safely and efficiently to treat early caries and remineralise white spot lesions on the enamel.
RESUMO
Background: A variety of surgical and nonsurgical management options for small renal masses (SRMs) now exist. Surgery in the form of partial nephrectomy (PN) has three different approaches. It is unclear which PN approach, if any, offers superior clinical outcomes. Aim: The aim of this study is to compare outcomes in patients with SRMs <4 cm undergoing PN through the open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN), or robotic partial nephrectomy (RPN) approach and to establish the advantages and disadvantages of the various approaches. Methods: A systematic literature search was conducted for studies comparing at least two of the above techniques. Eighteen studies and 17,013 patients were included in our study. A network meta-analysis with a frequentist framework was performed. OPN was used as the baseline comparator. The prespecified primary outcome was R0 resection rates. Secondary outcomes included operating time, ischemia time, blood loss, transfusion rates, urine leak rates, significant morbidity, length of stay, and recurrence. Results: There was no significant difference between the techniques in terms of R0 rates, tumor recurrence, urine leak rates, renal function, and >3a Clavien-Dindo complications. LPN had a longer ischemic time and operating time. OPN had a longer length of stay and higher average intraoperative blood loss. RPN had lower blood transfusion rates. Discussion: All approaches are acceptable from an oncological perspective. The minimally invasive approaches (i.e., RPN and LPN) offer advantages in terms of morbidity; however, LPN may increase ischemic time and operative duration. Variations between perioperative outcomes may influence the choice of approach on a case-by-case and institutional basis.

Data comparing hematopoietic stem cell transplantation (HSCT) using bone marrow (BM) or peripheral blood stem cell (PBSC) grafts in children after alemtuzumab-based conditioning are lacking. We investigated whether in vivo T cell depletion using alemtuzumab could reduce the risk of severe acute graft-versus-host disease (aGVHD) and chronic GVHD (cGVHD) after HSCT with matched unrelated donor (MUD) BM or PBSCs. This retrospective multicenter study included 397 children (BM group, n = 202; PBSC group, n = 195) who underwent first MUD HSCT at 9 pediatric centers in the United Kingdom between 2015 and 2019. The median age at transplantation was 7.0 years (range, .1 to 19.3 years), and the median duration of follow-up was 3.1 years (range, .3 to 7.5 years). The 3-year overall survival was 81% for the entire cohort (BM group, 80%; PBSC group, 81%). The incidence of grade II-IV aGVHD was significantly higher in the PBSC group (31%) compared to the BM group (31% versus 19%; P = .003), with no difference in the incidence of grade III-IV aGVHD (BM, 7%; PBSC, 12%; P = .17). CD3+ T cell dose >5 × 108/kg and the use of PBSCs were independent predictors of grade II-IV aGVHD. When considering CD3+ T cell dose and GVHD prophylaxis, PBSC transplantation with a calcineurin inhibitor (CNI) and mycophenolate mofetil (MMF) and a CD3+ T cell dose ≤5 × 108/kg had a comparable grade II-IV aGVHD to BM transplantation plus a CNI (20% versus 18%; P = .52). PBSC transplantation was associated with a lower incidence of cGVHD compared to BM transplantation (6% versus 11%; P = .03). Within the limits of this study, we identified a potential strategy to reduce the risk of severe GVHD in pediatric PBSC recipients that includes a combination of in vivo T cell depletion using alemtuzumab and dual GVHD prophylaxis (with a CNI and MMF) and limiting the CD3+ T cell dose to ≤5 × 108/kg.

Bio-inspired molecular-engineered systems have been extensively investigated for the half-reactions of H2 O oxidation or CO2 reduction with sacrificial electron donors/acceptors. However, there has yet to be reported a device for dye-sensitized molecular photoanodes coupled with molecular photocathodes in an aqueous solution without the use of sacrificial reagents. Herein, we will report the integration of SnIV - or AlIII -tetrapyridylporphyrin (SnTPyP or AlTPyP) decorated tin oxide particles (SnTPyP/SnO2 or AlTPyP/SnO2 ) photoanode with the dye-sensitized molecular photocathode on nickel oxide particles containing [Ru(diimine)3 ]2+ as the light-harvesting unit and [Ru(diimine)(CO)2 Cl2 ] as the catalyst unit covalently connected and fixed within poly-pyrrole layer (RuCAT-RuC2 -PolyPyr-PRu/NiO). The simultaneous irradiation of the two photoelectrodes with visible light resulted in H2 O2 on the anode and CO, HCOOH, and H2 on the cathode with high Faradaic efficiencies in purely aqueous conditions without any applied bias is the first example of artificial photosynthesis with only two-electron redox reactions.
RESUMO
Non-tuberculous mycobacteria (NTM) are ubiquitous organisms. Endobronchial growth as a presenting feature of NTM disease is uncommon. Here we present a case of a patient with retroviral disease on antiretroviral therapy, presenting with cough, wheezing and exertional dyspnoea. High-resolution CT showed a partial obstruction of the left main bronchus (LMB). Bronchoscopy showed an endobronchial growth in the distal LMB. An endobronchial biopsy showed non-necrotising granulomas; bronchial wash for acid-fast bacilli was positive and culture grew Mycobacterium avium complex. He was treated with a combination therapy of clarithromycin, rifampicin and ethambutol. Repeat bronchoscopy after 6 weeks of therapy showed complete resolution of the endobronchial growth.

Faced with the new stage of water oxidation by molecular catalysts (MCs) in artificial photosynthesis to overcome the bottle neck issue, the "Photon-flux density problem of sunlight," a two-electron oxidation process forming H2O2 in place of the conventional four-electron oxidation evolving O2 has attracted much attention. The molecular characteristics of tin(IV)-tetrapyridylporphyrin (SnTPyP), as one of the most promising MCs for the two-electron water oxidation, has been studied in detail. The protolytic equilibria among nine species of SnTPyP, with eight pKa values on the axial ligands' water molecules and peripheral pyridyl nitrogen atoms in both the ground and excited states, have been clarified through the measurements of UV-vis, fluorescence, 1H NMR, and dynamic fluorescence decay behaviour. The oxidation potentials in the Pourbaix diagram and spin densities by DFT calculation of the one-electron oxidized form of each nine species have predicted that the fully deprotonated species ([SnTPyP(O-)2]2-) and the singly deprotonated one ([SnTPyP(OH)(O-)]-) serve as the most favourable MCs for visible light-induced two-electron water oxidation when they are adsorbed on TiO2 for H2 formation or SnO2 for Z-scheme CO2 reduction in the molecular catalyst sensitized system of artificial photosynthesis.

Osteonecrosis of the metaphysis is often rare as it is a highly vascular region. Here we report an unusual case of non-traumatic osteonecrosis of the humerus predominantly involving the metaphysis in a post covid elderly female. The patient had a pathological fracture of humerus during the post-operative period of intertrochanteric femur fracture surgery. She was evaluated for the causes of pathological fracture and the fracture was managed with hemi replacement of the shoulder because of the extensive bone loss. The pathology here could only be explained as some sequelae of hyper inflammatory state associated with COVID-19 infection. The possible differentials are also discussed here. This case report will help clinicians to consider COVID-19 infection as a cause for non-traumatic osteonecrosis among other reported causes of osteonecrosis.

Objective: The goal of this systematic review was to evaluate the therapeutic efficacy of Casein Phosphopeptide Amorphous Calcium Phosphate (CPP-ACP) remineralizing potential to that of other remineralizing treatments and placebo in both naturally occurring and postorthodontic white spot lesions (WSL) in vivo. Materials and Methods: From 2005 to 2020, the literature search used electronic databases PubMed, Embase, Science Direct, and Google Scholar to find studies published solely in English and randomized controlled trials (RCTs) employing CPP-ACP as an intervention. All eligible studies were reviewed by two independent reviewers. Results: Excluding duplications, 72 articles were identified. Abstracts of 58 articles were reviewed independently, 19 articles were excluded, 36 full text articles were retrieved; finally selecting 14 studies. Conclusion: The CPP-ACP was found to have efficacious remineralizing potential on naturally occurring and postorthodontic WSL compared to placebo or other preventive measures. Further well-performed RCTs are needed to determine the therapeutic significance of remineralizing medicines, and long-term follow-ups are required.
RESUMO
Background: Many studies explained the importance of remineralisation of early carious lesions with various remineralising agents. In the present study, we incorporated the remineralising agents in a dentifrice, applied that in artificial enamel caries and evaluated their remineralising potential and compared the efficacy among the three. Aim: To evaluate and compare the remineralisation potential of a dentifrice containing bioactive glass, casein phosphopeptide-amorphous calcium phosphate and novel laboratory synthesised strontiumdoped nanohydroxyapatite paste in artificial enamel caries. Methods and Materials: 120 enamel specimens were divided into 4 groups of 30 specimens each, based on the type of dentifrice applied: GI - conventional toothpaste (control group), GII - calcium sodium phosphosilicate (Novamin), GIII - casein phosphopeptide-amorphous calcium phosphate (GC tooth mousse) and GIV- Novel strontiumdoped nanohydroxyapatite paste (SrnHAp paste). Specimens in all the groups were subjected to demineralisation, and calcium/phosphorous ratio was analysed followed by remineralisation and the mean calcium-phosphorus ratio was assessed using a scanning electron microscope and energy dispersing X-ray analysis. Statistical Analysis: Data were analysed using IBM SPSS Statistics for Windows Software, version 22 (IBM Corp., Armonk, NY, USA). Descriptive statistics were used to calculate the mean and standard deviation. Kruskal-Wallis, ANOVA and Mann-Whitney tests were used. The level of significance was set at 5%. Results and Conclusion: All except the control group showed a net increase in calcium and phosphorous values after application of the respective remineralising agents in respective groups. Inter-group comparison revealed that Group IV - SrnHAp paste yields higher net calcium and phosphorous values than other groups. Hence, novel SrnHAp can be considered as the material of choice in remineralising early enamel carious lesions.

Introduction: Emphysematous osteomyelitis (EO) is an uncommon and deadly pathology characterized by occurrence of intraosseus air within the bone. However, only few of them have been reported. The use of local antibiotic delivery system has proven to be very effective in bone and joint infections as they offer decreased hospital stay and early clearance of infection. To the best of our knowledge, there are no reports on local antibiotic delivery using absorbable synthetic calcium sulfate beads in EO. Case Report: A 59-year-old male with Type II diabetes mellitus, chronic kidney, and liver disease came with pain and swelling over left leg. After blood investigations and radiological evaluation, he was diagnosed to have EO of tibia with unknown source of infection. We successfully treated him with immediate surgical decompression and application of antibiotic impregnated absorbable calcium sulfate beads locally for improved local antibiotic delivery. Following this, he was further treated with culture sensitive intravenous antibiotics and his symptoms resolved. Conclusion: Early diagnosis and aggressive surgical intervention along with local antimicrobial therapy using calcium sulfate beads can offer better outcome in EO. The local antibiotic delivery system can decrease the use of prolonged intravenous antibiotic therapy and long hospital stay.
RESUMO
BACKGROUND: Dentists are the common preys for the transmission of pandemic disease because of the airborne spread via routine dental checkups. This study which is a cross-sectional one gives the idea about awareness and alertness of dentists about COVID-19 in Kerala, India. MATERIALS AND METHODS: The survey comprised 25 closed-ended questions. The survey was separated into two sections. The initial segment of the poll was identified with the socio-segment qualities that were researched, while the subsequent part was worried about dental practitioners' perspectives toward the management of COVID-19 and the apparent danger of defilement in dental facilities. RESULTS: Coronavirus management in dental clinics differs regarding adherence to the rules. An aggregate of 750 respondents finished the form, out of which 686 (91.46%) complete reactions were incorporated. The majority of the respondents concurred on inquiries regarding the knowledge, practice, and mentality of dental specialists toward the COVID-19 pandemic. CONCLUSION: The feedback of most dental specialists with respect to the readiness and view of disease control measures against the COVID-19 pandemic was positive. Dental facilities need to adhere more to the central and state government suggestions in alertness of their facilities or by tutoring their dental specialists and staff.
RESUMO
AIMS: The aim of the study was to assess the correlation between body mass index (BMI) and dental caries of 13-15-years-old school children in urban Bangalore and to compare the correlation between BMI and dental decay amongst government and private school children of age group 13-15 years in Bangalore city. SUBJECTS AND METHODS: A total of 660 students 13-15 years old were inducted in the study. According to these, 330 students from government schools and 330 students from private schools were examined. A specially designed structured questionnaire was used for compilation of data in the survey. BMI for age percentiles was deducted by weight in kilogram divided by height in meter square. RESULTS: Overall a positive correlation was found between Decayed, Missing, and Filled Teeth DMFT and BMI. In government schools, Overweight children had more mean DMFT (1.43) than other BMI categories while in Private schools, At risk of overweight children had more mean DMFT (1.4) than other category of BMI children. CONCLUSIONS: A positive correlation was found between DMFT and BMI. In government schools, Overweight children had more mean DMFT than other BMI category while in Private schools, At risk of overweight children had more mean DMFT than other category children.
RESUMO
We describe and characterize a dual-channel incoherent broadband cavity-enhanced absorption spectrometer (DC-IBBCEAS) for the sensitive measurements of NOx: the sum of nitrogen monoxide (NO) and nitrogen dioxide (NO2) in the atmosphere. The instrument employs two 1 m long optical cavities, with air being extracted from a common sampling line. The first channel (cavity-1) spans 340-380 nm and the second channel (cavity-2) spans the 405-460 nm spectral range, both measuring NO2 simultaneously. High absorption cross-sections of NO2 in both channels are effectively utilized for its sensitive quantification. NO is quantified by titrating it with ozone to NO2 in channel-2, where the difference of NO2 measured from that in channel-1 corresponds to the NO concentration in the sampled air. The instrument offers 1-ppb detection sensitivity for both NO and NO2 with a maximum possible uncertainty of â¼9%. The use of close yet different spectral regions in the two channels readily extended measurements to a broader range without compromising its sensitivity to NOx quantification. This would extend the DC-IBBCEAS applicability to simultaneously monitor interfering species with significant absorption cross-sections in the region in either channel, such as glyoxal (CHOCHO), methylglyoxal (CH3COCHO), and nitrous acid (HONO).
RESUMO
BACKGROUND: Many of the contents of cigarette smoke are genotoxic in nature, and consequently, cytogenetic injury seems to be a trustworthy biomarker for deciding the influence of exposure to chromosome damaging agents in smoke. The cytokinesis-block micronucleus assay (CBMN assay) has been proven to be an effectual tool for the study of micronuclei (MN) that will help in estimating the genotoxicity in tobacco users alone which will further help in early cancer detection. OBJECTIVE: The objective is to find out whether there is pronounced contrast in genotoxicity between tobacco users and nonusers by determining MN number in peripheral blood lymphocytes using CBMN assay. METHODOLOGY: MN frequency in peripheral blood lymphocytes was estimated in 5 ml of fresh blood obtained from sixty individuals using tobacco either smoking, chewing, or combination of both and also from thirty individuals with no habit of tobacco use. All were in the age group of 20-40 years. RESULTS: There was a significant increase in genotoxicity in tobacco users when compared to that of nontobacco users. A positive correlation was also obtained between smoking index and MN frequency in the study. CONCLUSION: Approximation of frequency of MN by CBMN assay can be used to evaluate the genotoxicity present in blood and helps in identifying tobacco users who are at a high risk for the presence of cancer even before the appearance of clinical changes.
RESUMO
BACKGROUND: The decision to perform a partial nephrectomy (PN) relies largely upon the complexity of the renal mass and its surrounding anatomy. The presence of adherent perinephric fat (APF) can increase surgical complexity and extend operative times. The accurate prediction of APF may improve surgical planning and aid in decision making for the surgical approach. OBJECTIVE: We sought to develop and externally validate a score that predicts APF based on preoperative clinical and radiological prognostic factors. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analyzed 495 consecutive patients who underwent open or minimally invasive PN. APF was defined as the presence of "dense," "adherent," or "sticky" perinephric fat at the time of dissection by the surgeon, and this did not require subcapsular dissection. Additionally, we analyzed an independent cohort of 285 patients for external validation. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A score model was developed using multivariate logistic regression analysis. Calibration of the fitted model was assessed graphically with a plot of the predicted versus the actual probability of APF, and discrimination was assessed by calculating the area under the receiver operating characteristic curve. RESULTS AND LIMITATIONS: Of the 495 patients, 95 (19%) had APF. Patients with APF had longer operative (p=0.02) and arterial clamp (p=0.01) times than non-APF patients. On multivariate analyses, diabetes mellitus (p=0.009), posterior perinephric fat thickness (p<0.001), and perinephric stranding (p<0.001) were predictors of encountering APF in PN. A risk score ranging from 0 to 4 was developed based on these three variables to predict APF. The scoring system demonstrated good discrimination of 0.82 and 0.84 for the development and external validation cohorts, respectively. CONCLUSIONS: The APF score can accurately predict the presence of APF in patients with a small renal mass who are planning to undergo PN. This score could aid in pre- and intraoperative planning and impact the surgical approach. PATIENT SUMMARY: The presence of "sticky" fat surrounding the kidney in patients undergoing partial nephrectomy has previously been linked to longer operative times, intraoperative complications, and surgical conversion. In our study, we found that this feature is more often presented in patients with diabetes mellitus, and thicker and more inflammatory fat on renal imaging. Based on these findings, we developed a risk score that can accurately predict this feature before surgery, in order to improve surgical planning and better counsel the patients.

PURPOSE: Urological service provision has changed dramatically with the advent of the SARS-CoV-2, necessitating restructuring and reorganization. The aim of this study was to review the reorganization of our unit, map the change in volume of departmental activities and discuss potential solutions. METHODS: Departmental activities over the months of April and May 2020 and 2019 were analysed. Details of admissions, operations, diagnostic procedures, outpatient reviews, morbidities and mortalities were recorded. Operations were performed on two sites, with elective operation transferred to an offsite, COVID-free hospital. RESULTS: Seventy-four emergency operations were performed onsite, with 85 elective operations outsourced. A total of 159 operations were performed, compared with 280 in the same period in 2019. Five (5.0%) of 101 admitted patients to the COVID hospital contracted COVID-19. No patients outsourced to the COVID-free hospital were infected there. Outpatient referrals to urology service decreased from 928 to 481. There was a 66% decrease in new cancer diagnoses. A virtual review clinic was established, with remaining outpatients reviewed through a telephone clinic platform. CONCLUSION: Compared with 2019, we performed fewer operations and outpatient procedures, had fewer admissions and diagnosed fewer patients with new cancers. However, outsourcing elective operation to designated non-COVID hospitals prevented the infection of any patient with COVID-19 in the post-operative period. The use of virtual clinic and telephone clinic has had some success in replacing traditional outpatient visits. The overall significant decrease in operative volume will likely precipitate a mismatch between demand and service provision in the coming months, unless capacity is increased.

BACKGROUND: With among the lowest urologist per population ratios in Europe, the demand for urology specialist review in Ireland far exceeds supply. Lower urinary tract symptoms (LUTS) account for a significant number of referrals. The traditional paradigm of every patient being reviewed in a consultant-led clinic is unsustainable. New models of care with nurse-led clinics represent an opportunity to optimise limited resources. METHODS: Existing long-waiting male LUTS referrals were triaged to a specialist nurse-led LUTS clinic. After urology CNS assessment, charts were reviewed by a consultant urologist and a plan formulated. Relevant data were prospectively collected and analysed. RESULTS: Fifty-eight new male patients with LUTS were seen over a 6-month period with an average waiting time of 15.8 months. Patients were assessed with uroflowmetry, IPSS and DRE. Mean age was 64, IPSS 14.5, Qmax 18.3 ml/s and PVR 89 ml. Thirty patients (52%) were discharged directly with lifestyle modification and medical therapy. Twenty-eight patients (48%) required one or more further investigations and subsequent review; 11 had flexible cystoscopy, 4 had urodynamics, 5 had prostate MRI, and 2 patients were listed for surgery (TURP and circumcision). The remaining 10 patients were for review post trial of lifestyle modifications and/or medical treatment. After review/investigations, 4 more patients were discharged. A total of 32 patients (55%) were discharged or listed for surgery after initial assessment. This total increased to 62% after a second review/investigations. CONCLUSION: Introduction of a CNS-led LUTS clinic has significantly reduced the number of patients requiring follow-up in general urology clinics, representing a quality improvement in service provision.

BACKGROUND: Postchemotherapy retroperitoneal lymphadenectomy (PC-RPLND) is an essential, yet potentially morbid, therapy for the management of patients with advanced germ cell tumors. In the current study, the authors sought to define the complication profile of PC-RPLND using validated grading systems for intraoperative adverse events (iAEs) and early postoperative complications. METHODS: Between 2000 and 2018, all patients who underwent PC-RPLND were analyzed for iAEs and early postoperative complications using the Kaafarani and Clavien-Dindo classifications, respectively. Logistic regression models were conducted to assess patient and tumor factors associated with iAEs and postoperative complications. RESULTS: Of the 453 patients identified, 115 patients (25%) and 252 patients (56%), respectively, experienced an iAE and postoperative complication. Major iAEs (grade ≥3) were observed in 15 patients (3%) and major postoperative complications (grade ≥3) were noted in 80 patients (18%). The most common iAE was vascular injury (112 of 132 events; 85%), which occurred in 92 patients (20%), and the most frequent postoperative complication was ileus, which occurred in 121 patients (27%). Original and postchemotherapy retroperitoneal mass size, nonretroperitoneal metastases, intermediate and/or poor International Germ Cell Cancer Collaborative Group classification, previous RPLND, elevated tumor markers at the time of RPLND, and anticipated adjuvant surgical procedures increased the risk of both iAEs and postoperative complications. Patients who experienced an iAE were significantly more likely to experience a postoperative complication (odds ratio, 2.50; 95% confidence interval, 1.58-3.97 [P < .001]). CONCLUSIONS: In what to the authors' knowledge is the first analysis of PC-RPLND using validated classifications for both iAEs and postoperative complications, advanced disease and surgical complexity significantly increased the risks of major iAEs and postoperative complications. Standardized reporting of adverse perioperative events allows providers and patients to appreciate the consequences of PC-RPLND during counseling and decision making.

PURPOSE: The use of mobile health (mHealth) technologies to augment patient care enables providers to communicate remotely with patients enhancing the quality of care and patient engagement. Few studies evaluated predictive factors of its acceptance and subsequent implementation, especially in medically underserved populations. METHODS: A cross-sectional study of 151 cancer patients was conducted at an academic medical center in the USA. A trained interviewer performed structured interviews regarding the barriers and facilitators of patients' current and desired use of mHealth technology for healthcare services. RESULTS: Of the 151 participants, 35.8% were male and ages ranged from 21 to 104 years. 73.5% of participants currently have daily access to internet, and 68.2% currently own a smartphone capable of displaying mobile applications. Among all participants, acceptability of a daily mHealth application was significantly higher in patients with a college-level degree (OR 2.78, CI95% 1.25-5.88) and lower in patients > 80 years of age (OR 0.05, CI95% 0.01-0.23). Differences in acceptability when adjusted for current smartphone use and daily access to internet were nonsignificant. Among smartphone users, the desire to increase cancer knowledge was associated with a higher likelihood of utilizing a mHealth application (OR 261.53, CI95% 10.13-6748.71). CONCLUSION: The study suggests that factors such as age, educational achievement, and access to internet are significant predictors of acceptability of a mHealth application among cancer patients. Healthcare organizations should consider these factors when launching patient engagement platforms.
