Feasibility of Pure Laparoscopic Donor Right Hepatectomy Compared With Open Donor Right Hepatectomy: A Large Single-center Cohort Study

OBJECTIVE

This study aimed to compare the morbidity of living donors and recipients after pure laparoscopic donor right hepatectomy (PLDRH) and open donor right hepatectomy (ODRH).

BACKGROUND

Donor and recipient morbidity have not been sufficiently reported in large-scale comparisons of PLDRH and ODRH.

METHODS

This retrospective study reviewed 3348 donors who underwent PLDRH (n = 329) and ODRH (n = 3019) and their corresponding recipients (n = 3348) between January 2014 and August 2023. Donor complications and recipient biliary complications within 90 days were evaluated before and after 1:3 propensity score matching (PSM). Multivariate logistic regression analyses identified significant risk factors for donor major and biliary complications, as well as recipient bile leakage and biliary stricture.

RESULTS

For donors, PLDRH had fewer overall complications than ODRH (0.9% vs 3.7%, P = 0.009), with no significant differences in major (Clavien-Dindo III/IV) complications ( P = 0.057) and biliary complications ( P = 0.067), despite the absence of biliary complications in PLDRH. However, PLDRH showed longer warm ischemic time and operation time, and higher peak aspartate aminotransferase and alanine aminotransferase levels compared with ODRH in donors ( P < 0.001). These results remained consistent after PSM. Recipient biliary complications were comparable between PLDRH and ODRH, both before ( P = 0.806) and after PSM ( P = 0.149). Multiple portal veins were significant donor risk factors for major ( P = 0.022) and biliary complications ( P = 0.001). Separated multiple bile ducts were a common significant recipient risk factor for bile leakage ( P = 0.007) and biliary stricture ( P = 0.022).

CONCLUSIONS

PLDRH could become the standard for donor right hepatectomy with careful consideration of portal and biliary variations for donor and recipient safety.

Risks Associated with Recent Self-Harm in Preadolescent and Adolescent Youth: Parent-Report

OBJECTIVE

Self-harm among children and adolescents is a global public health issue, with concerning trends of increased rates of hospital presenting self-harm in younger age groups (5-12 years). Few studies have investigated risk factors of emerging self-harm in preadolescent populations (<12 years). This study aimed to identify key factors associated with recent (past 12-months) self-harm in preadolescents (5-12 years) compared to adolescents (13-18 years).

METHOD

This cross-sectional case-control study recruited 305 parents/guardians who had a child (aged 5-18 years) that had (i) recently engaged in self-harm (case group) or (ii) never engaged in self-harm (control group). Participants completed an online parent-report questionnaire that assessed demographic characteristics and self-harm, childhood adversity, child-parent relationships, peer relationships, and problematic digital media use. Data were analyzed using univariate and multivariate logistic regression analyses.

RESULTS

Poorer emotion regulation (OR = 1/0.76 = 1.32), lower parental age (OR = 1/0.83 = 1.20), lower household income (OR = 4.38), problematic peer relationships (OR = 1.38), and lifetime suicidal ideation (OR = 20.34) were associated with increased odds of self-harm among all youth ages. Higher parent education was associated with greater odds of self-harm among preadolescents (OR = 0.02). Lifetime mental health diagnosis (OR = 7.84) and lower levels of childhood adversity (OR = 0.60) were associated with greater odds of recent self-harm among adolescents.

CONCLUSIONS

Coordinated multi-agency efforts are essential for holistically addressing common, modifiable individual, social, and socioeconomic risk factors of youth self-harm that may help to prevent onset in young people.

Development and Assessment of a Patient-Reported Outcome Instrument for Gender-Affirming Care

Importance

There is an urgent need for a validated gender-affirming care-specific patient-reported outcome measure (PROM).

Objective

To field test the GENDER-Q, a new PROM for gender-affirming care, in a large, international sample of transgender and gender diverse (TGD) adults and evaluate its psychometric properties.

Design, Setting, and Participants

This international cross-sectional study was conducted among TGD adults aged 18 years and older who were seeking or had received gender-affirming care within the past 5 years at 21 clinical sites across Canada, the United States, the Netherlands, and Spain; participants were also recruited through community groups (eg, crowdsourcing platform, social media). The study was conducted between February 2022 and March 2024. Participants had to be capable of completing the instrument in English, Danish, Dutch, or French-Canadian. Eligible participants accessed an online REDCap survey to complete sociodemographic questions and questions about gender-affirming care they had received or sought (ie, to look, function, or feel masculine, feminine, gender fluid, or another way).

Main Outcome and Measures

Branching logic was used to assign relevant instrument scales. Rasch measurement theory (RMT) analysis was used to examine the fit of the observed data to the Rasch model for each scale. Test-retest reliability and hypothesis-based construct validity of instrument scales were examined. The hypothesis was that instrument scale scores would increase with better outcomes on corresponding categorical questions.

Results

A total of 5497 participants (mean [SD] age, 32.8 [12.3] years; 1837 [33.4%] men; 1307 [23.8%] nonbinary individuals; and 2036 [37.0%] women) completed the field test survey. Participants sought or had the following types of gender-affirming care: 2674 (48.6%) masculinizing, 2271 (41.3%) femininizing, and 552 (10.0%) other. RMT analysis led to the development of 54 unidimensional scales and 2 checklists covering domains of health-related quality of life, sexual, urination, gender practices, voice, hair, face and neck, body, breasts, genital feminization, chest, genital masculinization, and experience of care. Test-retest reliability of the scales (intraclass correlation coefficient [average] >0.70) was demonstrated. Only 1 item (phalloplasty donor flap) had an ICC less than 0.70. As hypothesized, scores increased incrementally with better associated self-reported categorical responses. For example, among 661 participants who reported poor psychological well-being, the mean (SD) scale score was 45 (18) points; for those who reported excellent psychological well-being, the mean (SD) scale score was 85 (16) points (P < .001).

Conclusions and Relevance

In this cross-sectional study of 5497 TGD adults, the instrument demonstrated reliability and validity. The instrument was validated in an international sample and is designed to collect and compare evidence-based outcome data for gender-affirming care from the patients' perspective.

Patient Participation in Multidisciplinary Team Meetings in Residential Mental Health Services: An Explorative Study of Patients' Perception

INTRODUCTION

The lack of evidence of mental health patients' perception on patient participation in multidisciplinary team meetings (MTMs) is a potential threat to the person-centeredness of care.

AIM

To explore the perceptions of mental health patients regarding patient participation in MTMs and to identify factors associated with these perceptions.

METHOD

In a cross-sectional study, 127 former and 109 currently admitted mental health patients completed the Patient Participation during Team Meetings Questionnaire (PaPaT-Q). The STROBE-checklist was used for reporting the study.

RESULTS

Overall, patients' perceptions were positive. Former patients expressed greater willingness to participate in MTMs, considered participation as more important, and felt more competent. These patients also exhibited a stronger preference for an autonomous role in medical decision making when participating in MTMs. The perception varied across factors such as gender, educational level, nature of psychological complaints and prior experience(s) with participation in MTMs.

DISCUSSION

These findings may help mental healthcare professionals to become more aware to factors associated with mental health patients' perception of patient participation in MTMs.

IMPLICATIONS

The results can be used by mental healthcare professionals to motivate mental health patients in an even more tailor-made basis to participate in MTMs when admitted in a hospital.

Oral viral, fungal, and bacterial infections linked to comorbidities: A case series from a Brazilian referral center

Background

Oral infections exhibit variability in their causative agents and clinical presentations, underscoring the necessity of accurate diagnosis for effective management. Despite extensive documentation globally, data on these infections from Brazil remain scarce. This study aimed to assess the occurrence, clinical features, and differential diagnosis of oral viral, fungal, and bacterial infections at a single center in southern Brazil.

Material and Methods

A retrospective analysis was conducted between 2010 and 2023. Clinicodemographic data, comorbidities, and routine medication use were analyzed descriptively and statistically.

Results

A total of 462 cases were included. The median age was 49.5 years (range: 2-100). Viral infections were the most frequent (65.8%), with squamous papilloma accounting for 49.4% of cases. Fungal infections comprised 29.4% of cases, predominantly erythematous candidiasis (20.8%) and pseudomembranous candidiasis (5.6%). These infections were more common in women, older adults (p<0.001), and individuals with comorbidities such as systemic arterial hypertension (p=0.006) and diabetes mellitus (p=0.028). Bacterial infections were rare (4.8%), with actinomycosis being the most frequent (2.2%).

Conclusions

Data from our series on oral viral, fungal, and bacterial infections align with the literature. The results emphasize the importance of tailored diagnostic approaches, particularly for at-risk patient populations. Key words:Bacterial infections, Communicable diseases, Mycoses, Oral manifestations, Virus diseases.

Dental and Craniofacial Anomalies in Fanconi Anemia: A Systematic Review and Additional 46 Reports

OBJECTIVE

Fanconi anemia (FA), a rare genetic disorder, has not been comprehensively studied regarding its dental and craniofacial phenotypes. This study aimed to systematically review the available evidence on dental, occlusion, and craniofacial anomalies in individuals with FA and to describe the occurrence of these anomalies in a cohort from two Brazilian referral centers.

MATERIALS AND METHODS

Electronic searches were conducted across six databases, supplemented by manual searches and gray literature. The Brazilian cohort included 46 patients diagnosed with FA.

RESULTS

A total of 19 articles describing 158 cases of FA were analyzed. The estimated prevalence of dental/craniofacial anomalies ranged from 13.3% to 71.4%. In our cohort, 93.5% of patients exhibited anomalies, primarily root abnormalities (69.6%), tooth rotation (54.3%), and tooth agenesis (26%). Males (p = 0.031) and individuals with endocrine disorders (p = 0.047) were more likely to experience alterations in eruption and/or exfoliation. Anomalies in size and shape were significantly more prevalent among individuals who had undergone hematopoietic stem-cell transplantation at age 14 or older (p = 0.002).

CONCLUSION

The high occurrence of dental/craniofacial anomalies in individuals with FA suggests that these anomalies are part of the disease's phenotypic spectrum, emphasizing the need to expand and standardize the diagnostic criteria of the disease.

Quantifying the Relationships Between Health Sector Strategic Planning Practices and Health Sector Results in Tanzania: A Cross-Sectional Study

Background and Aim

There is still limited evidence on the relationships between strategic planning practices and strategic results in the health sector. The study aimed to examine and quantify these relationships in Tanzania.

Methods

A cross-sectional study involving 290 council health managers from 23 councils was conducted. We used a questionnaire to collect data on health sector strategic planning practices and health sector results related to health sector strategic plan IV (HSSP). We analyze the data using descriptive methods analysis, factor analysis, and multiple regression analysis.

Results

Our findings showed separately that HSSP formulation practices had a positive, weak, and significant relationship with perceived health sector results; HSSP implementation practices had a positive, moderate, and significant relationship with perceived health sector results; HSSP monitoring and evaluation had a positive, strong, and significant relation with perceived health sector results. Furthermore, jointly, all the practices of HSSP formulation, implementation, and monitoring and evaluation were positively related to perceived strategic health sector results, and findings indicated that only HSSP implementation and monitoring and evaluation practices were significantly and positively related to the health sector results.

Conclusions

Our study provides additional evidence to the ongoing debate on the relationships between strategic planning practices and strategic results in the health sector and the public sector. Overall, our evidence suggests that only the HSSP implementation and HSSP monitoring and evaluation practices are significantly and positively related to strategic health sector results. We recommend that the council health managers continue to engage in the implementation, monitoring, and evaluation practices to enhance their chances of achieving the strategic results set out in the health sector strategic plans. We encourage future studies using longitudinal study design, objective and in other settings.

Depression, anxiety, stress, and job performance among Turkish nurses in the early post-earthquake period

BACKGROUND

Individual and social concerns can negatively affect nurses' mental health during a large-scale earthquake's early stages, making it challenging to perform their professional responsibilities.

AIM

This cross-sectional correlational study aimed to examine the relationship between depression, anxiety, and stress levels Turkish nurses experienced during an earthquake's early period. The nurses participating in this study were not directly present in the earthquake-affected area.

METHODS

The study was conducted on 232 nurses between February 10 and 25, 2023. The data were collected using the Depression, Anxiety, Stress-21 Scale and the Job Performance Evaluation Form developed by the researchers through a literature review. These were used to investigate nurses' work motivation changes due to the earthquake. The study followed the STROBE checklist for cross-sectional studies.

RESULTS

The participants' depression levels were severe, anxiety levels were extremely severe, and stress levels were moderate following the earthquake. Nurses who felt exhausted experienced reduced energy levels toward their work and reported a decrease in their desire, effort, and work motivation to perform well. In addition, they had higher depression, anxiety, and stress scores (p < 0.005).

CONCLUSION

Psychological difficulties, including depression, anxiety, and stress experienced by nurses not directly present in an earthquake-affected area, reduced their professional efforts and motivation and negatively affected the patient care process. Further studies should focus on conducting comparative studies in different cultures affected by natural disasters on the longitudinal analysis of the impacts of nurses' psychological distress on their job performance.

IMPLICATIONS FOR NURSING AND HEALTH POLICY

Nursing policymakers should be aware of the negative psychological effects experienced by nurses during the early post-earthquake period, even if they are not directly present in the earthquake-affected area. The study recommended that nurses should be provided with psychological support to deal with the negative effects of natural disasters and maintain job performance, including the nursing care process.

Economic Burden of Heart Failure Hospitalizations in Canada: A Population-based Study

Background

Heart failure (HF) is associated with significant mortality and morbidity and accounts for substantial health care resources. We examined hospitalization costs of patients with HF in Canada (excluding patients from Quebec and the Territories) between 2010/2011 and 2018/2019 and estimated future costs to 2039/2040.

Methods

We identified hospitalization records with a primary diagnosis of HF between 2010/2011 and 2018/2019. Concurrent hospitalizations were combined to identify episodes of care. Total hospitalization costs and costs per HF patient were calculated for each fiscal year of the study. All costs are presented in 2022 CAD$. Generalized linear models were used to project primary HF hospitalization episodes and costs to 2039/2040 on the basis of population projections from Statistics Canada.

Results

There were 436,160 hospitalization episodes with a primary diagnosis of HF. Between 2010/2011 and 2018/2019, HF episodes increased from 43,114 to 54,743, and number of patients increased from 34,960 to 44,567, and total hospitalization costs increased from $684.3 million to $776.0 million, resulting in a cumulative cost of $6.65 billion. Between 2019/2020 and 2039/2040, there are projected to be 1.69 million HF hospitalization episodes, costing the Canadian health care system $19.5 billion.

Conclusions

HF places a substantial economic burden on the Canadian health care system, which is likely to increase in the coming decades. Health system planning and policy solutions to identify, and reduce barriers to, HF therapies that are effective in preventing hospitalizations; and improved access to community-based services are needed to mitigate future costs.

Lack of Regular Access to Primary Care Physician Associated With Increased Emergency Department Visits Related to Survivorship Needs Among Rectal Cancer Survivors

BACKGROUND

With advances in rectal cancer management and improved prognosis, there is a growing number of rectal cancer survivors with unique needs.

OBJECTIVES

We hypothesized that a significant proportion of our rectal cancer survivors lack regular access to a primary care physician. Our study aimed to examine the association between access to a primary care physician and survivorship-related emergency department visits.

DESIGN

Retrospective cohort study of rectal cancer survivors who have finished all treatment.

PATIENTS

Patients with rectal cancer who underwent proctectomy and completed treatment from 2005 to 2021.

SETTING

Single tertiary care center in Quebec, Canada.

MAIN OUTCOME MEASURE

Survivorship-related emergency department visits.

RESULTS

In total, 432 rectal cancer survivors were included. The median age was 72 (interquartile range, 63-82) years, 190 (44.0%) were women, and the median Charlson Comorbidity Index was 5 (interquartile range, 4-6). There were 153 individuals (35.4%) not registered with a primary care physician. Sixty individuals visited the emergency department due to survivorship-related concerns. Using Cox proportional hazards analysis, lack of registration to primary care physicians was associated with a higher probability of having survivorship-related emergency department visits.

LIMITATIONS

This study was limited by observational design.

CONCLUSIONS

Lack of regular access to primary care physicians may contribute to increased emergency department visits among rectal cancer survivors. Efforts to improve access to a primary care physician and coordinate interdisciplinary care are needed to improve care for survivors. See Video Abstract.

Volatile sulfur compounds and salivary parameters in patients undergoing head and neck cancer treatment: A preliminary study

BACKGROUND

Treatment for head and neck squamous cell carcinoma (HNSCC) is often associated with various adverse effects, including changes in salivary parameters and complaints of halitosis. This study aimed to investigate changes in volatile sulfur compound (VSC) levels and salivary parameters in patients undergoing treatment for HNSCC.

METHODS

This prospective longitudinal study was conducted at a Brazilian oncology center, where a convenience sample of 24 HNSCC patients undergoing radiotherapy or chemoradiotherapy were evaluated for VSC levels, salivary flow, pH, viscosity, dry mouth, and tongue coating. Assessments were performed at the beginning and end of antineoplastic therapy. VSC levels were measured using an Oral Chroma™ gas chromatograph. Data were analyzed descriptively and analytically.

RESULTS

No significant changes were found in overall VSC levels. However, a statistically significant reduction in salivary flow (p < 0.001) and pH (p = 0.017) and an increase in salivary viscosity (p = 0.037) were noted post-treatment. Patients who reported halitosis after treatment exhibited significantly higher hydrogen sulfide levels (p = 0.045). Tongue coating and VSC levels showed no significant changes.

CONCLUSION

Treatment for HNSCC results in reduced salivary flow, altered pH, and increased salivary viscosity. Although self-reported halitosis correlates with elevated hydrogen sulfide levels post-treatment, no significant changes in overall VSC concentrations were observed.

Prevalence and Severity of Sleep Bruxism in Edentulous Patients: A Cross-Sectional Study

Aims: Edentulous patients can also suffer from sleep bruxism (SB), just like dentate patients. This study aims to evaluate the prevalence and severity of SB in edentulous patients using the definitive method. Methods: Twenty-three edentulous patients underwent treatment with new conventional complete dentures. Definitive SB was evaluated using the Bruxoff (portable electromyography device) while sleeping at home. The prevalence of SB was assessed by the Bruxmeter software, where SB was evaluated as "absent" (score zero), "light" (<2 episodes), "moderate" (between 2 and 4 episodes), or "severe" (>4 episodes). The prevalence was expressed with descriptive statistics in percentage using the number of detected cases out of the total number of patients. Results: Eighteen patients (78.26%) were diagnosed with SB. The severity of SB was 55.5%, 5.5%, and 39% for the light, moderate, and severe scores, respectively. Conclusions: Almost 8 out of 10 edentulous patients have SB. Approximately half of the SB-detected patients showed moderate to severe severity of bruxism as measured by a commercial, at-home device.

Cultural immersion in dietetics curricula: A method for ensuring Aboriginal pedagogies are used for Aboriginal educational content

AIMS

To describe an Aboriginal cultural immersion delivered to dietetics students at a large university in Australia and assess its effectiveness as a method to teach Aboriginal history, culture, diet, and health in dietetics.

METHODS

Taking a strength-based approach, Aboriginal processes of learning were privileged, with the cultural immersion being co-designed with immersion educators, a First Nations researcher, and dietetics academic. The cultural immersion consisted of an opening ceremony and four stations of yarning, weaving, bush tucker, and artefacts/medicines. A mixed-methods approach was used, with triangulation of data from pre- and postsurveys, station mapping, and focus group interviews. Quantitative and qualitative data were simultaneously analysed from participating first-year Master of Nutrition and Dietetics students and then drawn together for an integrated understanding of the impact of the cultural immersion on student learnings.

RESULTS

Fifty-three students completed pre- and postsurveys and 36 participated in focus groups. Through sharing lived experiences, learning through culture, and keeping sessions practical and Aboriginal leadership, each cultural immersion station utilised Aboriginal processes of learning that meaningfully engaged students with Aboriginal education content, appreciate holistic health and increased their general knowledge on Aboriginal history, culture, diet, and health (all p < 0.001).

CONCLUSION

Cultural immersion is one teaching method to enhance student knowledges and can be a part of a programmatic and integrated approach that embeds Aboriginal content throughout the whole curriculum. It is necessary that institutions recognise the value of cultural immersions to student learnings and commit to providing ongoing support.

Caregivers' perceptions of feeding practices and diet diversity among children aged 12-59 months in a rural district of South India: an analytical cross-sectional study

OBJECTIVE

The primary objective of this study was to assess caregivers' perceptions of feeding practices (breastfeeding and complementary feeding) and diet diversity among children aged 12-59 months in a rural district of South India. The secondary objective was to identify potential predictors of these perceptions and diet diversity.

DESIGN

An analytical cross-sectional study was performed from March 2023 to May 2023.

SETTING

In a rural district of Tamil Nadu, South India.

PARTICIPANTS

This study included 301 mothers/caregivers of children between 12 and 59 months of age in a rural district of Tamil Nadu. The research gathered demographic information from caregivers, including details such as age, educational background, occupation, relationship with the child and place of residence. Additionally, the caregivers' perspectives were evaluated through a questionnaire focused on breastfeeding/complementary feeding, and the diet diversity of the children was also assessed.

OUTCOME MEASURES

The primary outcome was the perceptions of mothers/caregivers of children between 12 and 59 months of age about breastfeeding/complementary feeding practices, and the diet diversity of the children was measured. Additionally, predictors associated with these perceptions were evaluated through regression analysis.

RESULTS

In the present study, 188 (62.5%) and 179 (59.5%) of the participants had good perceptions of breastfeeding practices and complementary feeding practices, respectively. This binomial regression revealed that subjects with unstable occupations (adjusted OR=2.24, 95% CI 1.25 to 4.01), schooling (7.71, 95% CI 2.73 to 8.9) and higher education (38.32, 95% CI 4.63 to 316.85) had increased chances of having good perceptions of breastfeeding practices. Subjects with unstable occupations (0.23, 95% CI 0.06 to 0.85), stable occupations (0.13, 95% CI 0.04 to 0.51), schooling (0.43, 95% CI 0.25 to 0.74), higher education (0.15, 95% CI 0.04 to 0.50) and increased birth weights (2.54, 95% CI 1.35 to 4.78) had increased chances of having good perceptions of complementary feeding practices (p<0.05). This study revealed that 86.4% of the children had adequate diet diversity.

CONCLUSION

The study revealed that most caregivers, particularly mothers, possess a strong understanding of breastfeeding and complementary feeding practices, with education and occupation exerting a notable influence. However, there is a crucial necessity to translate this knowledge into practical applications to effectively obtain feeding indicators.

Kinetics of neutrophil extracellular traps and cytokines in oral mucositis and Candida infection

OBJECTIVE

This study investigated the concentrations of neutrophil extracellular traps (NET) and salivary cytokines (IL-1β, IL-6, IL-8/CXCL8, TNF, and TGF-β1) in patients undergoing chemotherapy and their associations with oral mucositis (OM) and Candida infection.

MATERIALS AND METHODS

This prospective longitudinal study performed at a Brazilian service included 60 adults diagnosed with hematolymphoid diseases. Saliva samples were collected on days D0, D3, D10, and D15. Cytokines were analyzed by ELISA and NET formation by identification of the myeloperoxidase-DNA complex. Oral Candida spp. was cultured.

RESULTS

OM occurred in 43.3% of patients and oral candidiasis in 20%. However, 66% of individuals had positive cultures for C. albicans. Higher concentrations of IL-6, IL-8/CXCL8, and TNF and lower concentrations of TGF-β1 were observed in patients with OM. C. albicans infection contributed to the increase in IL-8/CXCL8, TGF-β1, and TNF. Individuals with OM or with oral candidiasis had significant reductions in NET formation. In contrast, individuals with C. albicans and with concomitant C. albicans and OM exhibited higher NET formation.

CONCLUSION

The kinetics of cytokine levels and NET formation in chemotherapy-induced OM appears to be altered by Candida infection, even in the absence of clinical signs of oral candidiasis.

Development of a single-item physical activity intention measure for adults with intellectual disabilities: Evidence of validity and reliability

BACKGROUND

Physical activity (PA) is important for overall health and well-being, but adults with intellectual disabilities often struggle to achieve adequate levels of PA. Therefore, it is necessary to understand their PA behaviour.

OBJECTIVE

To develop a Single-Item Physical Activity Intention Measure (SPAIM) to assess PA intentions of adults with intellectual disabilities and preliminarily analyse its psychometric properties in terms of validity and reliability.

METHODS

The study had three phases: developing the SPAIM, assessing its validity and reliability evidence, and conducting a cross-sectional survey to analyse the relationship between PA intentions (measured by SPAIM) and PA levels. Participants were recruited between September 2016 and August 2017 from diverse settings in Oxford, UK, to ensure representation across the intellectual disability spectrum.

RESULTS

There were 82 participants aged 20-68 (mean age 36 ± 13) years who had mild-profound intellectual disabilities. The study provided evidence of content- and response processes-related validity to ensure respondents' understanding. Additionally, test-criterion evidence was provided, showing a predictive correlation between PA intention and sedentary hours/day (12 % of the explained variability). However, there was no correlation between PA intention and PA minutes/week. The study also provided adequate test-retest evidence (r = 0.78).

CONCLUSIONS

SPAIM may be a valuable tool for measuring PA intention in adults with intellectual disabilities. Modifying PA intentions could prove crucial in reducing sedentary behaviour and improving the health outcomes of this population. Future research and application of SPAIM in varied contexts will deepen our understanding of PA intentions and explore its predictive characteristics.

Oral hygiene behaviors and periodontitis among patients with chronic diseases and its impact on tooth loss and oral health-related quality of life: a cross-sectional study of data from the ComPaRe e-cohort

OBJECTIVES

Little is known about oral hygiene habits of patients suffering from chronic diseases. This study aims to describe oral hygiene behavior (OHB) in terms of tooth brushing and professional scaling frequency among patients with chronic diseases. Secondarily, it aims to assess the association between OHB and periodontitis, tooth loss, and oral health-related quality of life (OHRQoL).

MATERIALS AND METHODS

This is a cross-sectional analysis of data of adult participants in the ComPaRe e-cohort. Participants were classified into having good, moderate, and poor OHB according to self-reported frequency of toothbrushing and professional tooth scaling. Periodontitis was assessed using the PEriodontal Screening Score (PESS). Weighted binary regression models were used to estimate the association between OHB and the following outcomes: (i) periodontitis; (ii) number of missing teeth; and (iii) OHRQoL based on the Oral Health Impact Profile-14.

RESULTS

Overall, 8553 patients were included in the analyses (52.9% females, mean age of 56.3 ± 17 years). Of these, 2907 (34%), 3953 (46%) and 1693 (20%) were considered as having good, moderate, and poor OHB, respectively. Over half (54.1%) of the patients had a PESS ≥ 5 suggestive for severe periodontitis. Moderate OHB was associated with lower odds of PESS ≥ 5 compared to poor OHB (Adjusted Odds Ratio, OR = 0.81 [95%CI: 0.70-0.92]). Good and moderate OHB were significantly associated with lower odds of ≥ 10 missing teeth (OR = 0.26 [95%CI: 0.21-0.33] and OR = 0.47 [95%CI: 0.4-0.56], respectively) and better OHRQoL than poor OHB.

CONCLUSIONS

Although, most of patients with chronic diseases reported to have good or moderate OHB, severe periodontitis is highly prevalent among this patient population in France.

CLINICAL RELEVANCE

This study describes OHB in a representative sample of patients suffering from one or more chronic diseases and provides an estimate of the prevalence of self-reported severe periodontitis, missing teeth, and OHRQoL.

Epidemiological breast cancer prediction by country: A novel machine learning approach

Breast cancer remains a significant contributor to cancer-related deaths among women globally. We seek for this study to examine the correlation between the incidence rates of breast cancer and newly identified risk factors. Additionally, we aim to utilize machine learning models to predict breast cancer incidence at a country level. Following an extensive review of the available literature, we have identified a range of recently studied risk factors associated with breast cancer. Subsequently, we gathered data on these factors and breast cancer incidence rates from numerous online sources encompassing 151 countries. To evaluate the relationship between these factors and breast cancer incidence, we assessed the normality of the data and conducted Spearman's correlation test. Furthermore, we refined six regression models to forecast future breast cancer incidence rates. Our findings indicate that the incidence of breast cancer is most positively correlated with the average age of women in a country, as well as factors such as meat consumption, CO2 emissions, depression, sugar consumption, tobacco use, milk intake, mobile cells, alcohol consumption, pesticides, and oral contraceptive use. As for prediction, the CatBoost Regressor successfully predicted future breast cancer incidence with an R squared value of 0.84 ± 0.03. An increased incidence of breast cancer is mainly associated with dietary habits and lifestyle. Our findings and recommendations can serve as a baseline for developing educational programs intended to heighten awareness amongst women in countries with heightened risk.

Assessing Risk Factors for Cognitive Decline Using Electronic Health Record Data: A Scoping Review

Background

The data and information contained within electronic health records (EHR) provide a rich, diverse, longitudinal view of real-world patient histories, offering valuable opportunities to study antecedent risk factors for cognitive decline. However, the extent to which such records' data have been utilized to elucidate the risk factors of cognitive decline remains unclear.

Methods

A scoping review was conducted following the PRISMA guideline, examining articles published between January 2010 and April 2023, from PubMed, Web of Science, and CINAHL. Inclusion criteria focused on studies using EHR to investigate risk factors for cognitive decline. Each article was screened by at least two reviewers. Data elements were manually extracted based on a predefined schema. The studied risk factors were classified into categories, and a research gap was identified.

Results

From 1,593 articles identified, 80 were selected. The majority (87.5%) were retrospective cohort studies, with 66.3% using datasets of over 10,000 patients, predominantly from the US or UK. Analysis showed that 48.8% of studies addressed medical conditions, 31.3% focused on medical interventions, and 17.5% on lifestyle, socioeconomic status, and environmental factors. Most studies on medical conditions were linked to an increased risk of cognitive decline, whereas medical interventions addressing these conditions often reduced the risk.

Conclusions

EHR data significantly enhanced our understanding of medical conditions, interventions, lifestyle, socioeconomic status, and environmental factors related to the risk of cognitive decline.

Oral Lesions of Immune-Mediated and Autoimmune Diseases: A 12-year Experience at a Single Brazilian Referral Center

BACKGROUND

Oral lesions of immune-mediated and autoimmune diseases have been well-documented, but studies from Brazil are limited. The varied spectrum of oral lesions within this demographic group poses challenges to clinicians, particularly when they occur in isolation. This study aimed to evaluate the occurrence, clinical characteristics, and management of patients with oral lesions of immune-mediated and autoimmune diseases at a single center in Brazil.

METHODS

A retrospective cross-sectional study was conducted from 2010 to 2022. Clinicodemographic data, histopathological features, and treatment modalities were analyzed descriptively and analytically.

RESULTS

Of the 3,790 oral and maxillofacial lesions diagnosed, 160 (4.2%) were confirmed as immune-mediated or autoimmune diseases. The population surveyed predominantly consisted of women (73.7%), with a mean age of 60.2 years. Oral lichen planus (51.3%), mucous membrane pemphigoid (MMP) (23.7%), and pemphigus vulgaris (PV) (19.4%) were the most prevalent lesions. The buccal mucosa (59.4%) was predominantly affected, with pain reported in 46.2% of cases, notably in individuals with PV and MMP. The average time to disease stabilization post-local and/or systemic corticosteroid therapy was 15.8 months for systemic lupus erythematosus, 8.7 months for MMP, and 6.5 months for PV.

CONCLUSION

Although oral lesions related to immune-mediated and autoimmune diseases are uncommon, their diverse clinicopathological aspects require multidisciplinary management.

Epidemiology of transient ischemic attack in the normandy stroke population-based study

INTRODUCTION

Transient ischemic attack (TIA) is a frequent neurological emergency which management and definition have changed radically over the last 15 years. However, recent epidemiological studies of TIA are scarce. We report here on the impact of the shift from a time-based to a tissue-based definition of TIA on its incidence and risk of recurrence in a new population-based cohort with a high rate of patients investigated by MRI.

MATERIALS AND METHODS

We prospectively included all TIAs that occurred between May 2017 and May 2021 from the Normandy Stroke Study, a population-based registry using multiple overlapping sources for exhaustive case identification in Caen la Mer area. TIAs were classified as either time-based (symptoms <24 h) or tissue-based (<24 h and no lesion on brain imaging). Attack and incidence rates were calculated, as was the 90-day ischemic stroke rate.

RESULTS

Five hundred and sixty-seven TIAs (549 single patients) were included, with 80.6% having a brain MRI. Four hundred and ten (72.3%) met the definition of tissue-based TIA. The age standardized attack (to the 2013 European population) rate was 39.5 (95% CI 35.7-43.5) and the age-standardized incidence rate (first ever cerebrovascular event) was 29.7 (95% CI 27.3-34.2). The overall recurrent stroke rate at 90 days was 2.7%, with no difference between patients with or without ischemic lesions on MRI.

CONCLUSION

We found that the use of the tissue-based definition of TIA resulted in a 27.5% reduction in incidence as compared to the time-based definition, but had no impact on the 90-day stroke rate. The burden of TIA remains high, and is likely to increase as the population ages.

Racial and Ethnic Inequities in Cancer Care Continuity During the COVID-19 Pandemic Among Those With SARS-CoV-2

Importance

Racially and ethnically minoritized US adults were disproportionately impacted by the COVID-19 pandemic and experience poorer cancer outcomes, including inequities in cancer treatment delivery.

Objective

To evaluate racial and ethnic disparities in cancer treatment delays and discontinuations (TDDs) among patients with cancer and SARS-CoV-2 during different waves of the COVID-19 pandemic in the United States.

Design, Setting, and Participants

This cross-sectional study used data from the American Society of Clinical Oncology Survey on COVID-19 in Oncology Registry (data collected from April 2020 to September 2022), including patients with cancer also diagnosed with SARS-CoV-2 during their care at 69 US practices. Racial and ethnic differences were examined during 5 different waves of the COVID-19 pandemic in the United States based on case surge (before July 2020, July to November 2020, December 2020 to March 2021, April 2021 to February 2022, and March to September 2022).

Exposures

Race and ethnicity.

Main Outcomes and Measures

TDD was defined as any cancer treatment postponed more than 2 weeks or cancelled with no plans to reschedule. To evaluate TDD associations with race and ethnicity, adjusted prevalence ratios (aPRs) were estimated using multivariable Poisson regression, accounting for nonindependence of patients within clinics, adjusting for age, sex, body mass index, comorbidities, cancer type, cancer extent, and SARS-CoV-2 severity (severe defined as death, hospitalization, intensive care unit admission, or mechanical ventilation).

Results

A total of 4054 patients with cancer and SARS-CoV-2 were included (143 [3.5%] American Indian or Alaska Native, 176 [4.3%] Asian, 517 [12.8%] Black or African American, 469 [11.6%] Hispanic or Latinx, and 2747 [67.8%] White; 2403 [59.3%] female; 1419 [35.1%] aged 50-64 years; 1928 [47.7%] aged ≥65 years). The analysis focused on patients scheduled (at SARS-CoV-2 diagnosis) to receive drug-based therapy (3682 [90.8%]), radiation therapy (382 [9.4%]), surgery (218 [5.4%]), or transplant (30 [0.7%]), of whom 1853 (45.7%) experienced TDD. Throughout the pandemic, differences in racial and ethnic inequities based on case surge with overall TDD decreased over time. In multivariable analyses, non-Hispanic Black (third wave: aPR, 1.56; 95% CI, 1.31-1.85) and Hispanic or Latinx (third wave: aPR, 1.35; 95% CI, 1.13-1.62) patients with cancer were more likely to experience TDD compared with non-Hispanic White patients during the first year of the pandemic. By 2022, non-Hispanic Asian patients (aPR, 1.51; 95% CI, 1.08-2.12) were more likely to experience TDD compared with non-Hispanic White patients, and non-Hispanic American Indian or Alaska Native patients were less likely (aPR, 0.37; 95% CI, 0.16-0.89).

Conclusions and Relevance

In this cross-sectional study of patients with cancer and SARS-CoV-2, racial and ethnic inequities existed in TDD throughout the pandemic; however, the disproportionate burden among racially and ethnically minoritized patients with cancer varied across SARS-CoV-2 waves. These inequities may lead to downstream adverse impacts on cancer mortality among minoritized adults in the United States.

Experience with 808-nm diode laser in the treatment of 47 cases of oral vascular anomalies

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

Neutrophil extracellular traps in rheumatoid arthritis and periodontitis: Contribution of PADI4 gene polymorphisms

AIM

We sought to investigate the release of neutrophil extracellular traps (NETs) in neutrophils from individuals with rheumatoid arthritis (RA) and controls and compare the presence of NETs in gingival tissues according to periodontal status. Also, the association between single nucleotide polymorphisms (SNPs) of the peptidyl arginine deaminase type 4 (PADI4) gene and the GTG haplotype with RA, periodontitis and NETs was evaluated in vitro.

MATERIALS AND METHODS

Peripheral neutrophils were isolated by density gradient, and NET concentration was determined by the PicoGreen method. Immunofluorescence was studied to identify NETs by co-localization of myeloperoxidase (MPO)-citrullinated histone H3 (H3Cit). Genotyping for SNPs (PADI4_89; PADI4_90; PADI4_92; and PADI4_104) was performed in 87 individuals with RA and 111 controls.

RESULTS

The release of NETs in vitro was significantly higher in individuals with RA and periodontitis and when stimulated with Porphyromonas gingivalis. Gingival tissues from subjects with RA and periodontitis revealed increased numbers of MPO-H3Cit-positive cells. Individuals with the GTG haplotype showed a higher release of NETs in vitro and worse periodontal parameters.

CONCLUSIONS

The release of NETs by circulating neutrophils is associated with RA and periodontitis and is influenced by the presence of the GTG haplotype.

Pre-existing chronic kidney disease, aetiology of acute kidney injury and infection do not affect renal outcome and mortality

BACKGROUND

We aimed to study the role of aetiology, pre-existing chronic kidney disease (CKD) and infections in acute kidney injury (AKI) on renal outcome and mortality.

METHODS

This retrospective study analysed patients with AKI admitted to a university nephrology department from January 1st, 2020 through December 31st, 2020. Aetiology of AKI, underlying renal disease in case of pre-existing CKD and presence of infections were assessed. Development of renal function and risk of death were studied with follow-up until January 31st, 2023.

RESULTS

Of 1402 patients screened, 432 patients (30.8%, 67.9 ± 15.4 years) fulfilled the inclusion criteria, half of the population presented with advanced CKD. Even though CKD patients were more often in need of chronic dialysis at time of discharge (6.9% vs 4.5%, p < .001), duration of hospital stay was shorter and in-hospital mortality tended to be lower when compared to AKI without prior renal disease. Neither aetiology of AKI nor pre-existing CKD had an impact on the combined endpoint of end-stage kidney disease and mortality (log rank 0.433 and 0.909). Overall, septic patients showed the highest in-hospital mortality (23.5%) and longest hospital stay (30.0 ± 22.8 days, p < .001), while patients with urosepsis had the shortest hospitalisation time (9.7 days) with lowest risk for dialysis (4.4%). Of note, outcome did not differ in patients with AKI when considering the infectious status.

CONCLUSIONS

Overall renal outcome and mortality in AKI patients were not affected by the cause of AKI, pre-existent CKD or infectious status. Only severity of AKI had a negative impact on outcome.

The prevalence and risk factors for phantom limb pain: a cross-sectional survey

BACKGROUND

We previously performed a systematic review and meta-analysis which revealed a Phantom Limb Pain (PLP) prevalence estimate of 64% [95% CI: 60.01-68.1]. The prevalence estimates varied significantly between developed and developing countries. Remarkably, there is limited evidence on the prevalence of PLP and associated risk factors in African populations.

METHODS

Adults who had undergone limb amputations between January 2018 and October 2022 were recruited from healthcare facilities in the Western and Eastern Cape Provinces. We excluded individuals with auditory or speech impairments that hindered clear communication via telephone. Data on the prevalence and risk factors for PLP were collected telephonically from consenting and eligible participants. The prevalence of PLP was expressed as a percentage with a 95% confidence interval. The associations between PLP and risk factors for PLP were tested using univariate and multivariable logistic regression analyses. The strength of association was calculated using the Odds Ratio where association was confirmed.

RESULTS

The overall PLP prevalence was 71.73% [95% CI: 65.45-77.46]. Persistent pre-operative pain, residual limb pain, and non-painful phantom limb sensations were identified as risk factors for PLP.

CONCLUSION

This study revealed a high prevalence of PLP. The use of effective treatments targeting pre-amputation pain may yield more effective and targeted pre-amputation care, leading to improved quality of life after amputation.

Influence of anxiety/depression on chemotherapy-induced oral mucositis and related quality of life: A prospective cohort study

OBJECTIVE

The impact of anxiety and depression on chemotherapy-induced oral mucositis has not been extensively explored in the literature. The aim of the present study was to evaluate anxiety/depressive symptoms, health-related quality of life, and oral health-related quality of life and their association with oral mucositis among individuals receiving chemotherapy.

METHODS

This is a prospective longitudinal study carried out at a Brazilian referral service. The Hospital Anxiety and Depression Scale (HADS), World Health Organization Quality of Life-BREF (WHOQOL-BREF), and Oral Health Impact Profile questionnaire (OHIP-14) were applied at D0 (before chemotherapy) and D15 of chemotherapy. Clinicodemographic data and oral mucositis severity scores were evaluated.

RESULTS

A total of 37 individuals (median age: 49 years) were included in the study. Nearly 38% of patients developed chemotherapy-induced oral mucositis and had higher anxiety/depression scores at baseline. Oral mucositis had a negative impact on oral health-related quality of life regarding functional limitation, physical pain, physical disability, and handicap.

CONCLUSION

Anxiety/depressive symptoms are associated with oral mucositis that affects overall health and oral health-related quality of life.

A Review of the Literature on the Multiple Forms of Stigmatization of Caregivers of Children with Autism Among Ethnic Minority Groups

Multiple forms of stigmatization are experienced by caregivers of children with autism among ethnic minority (EM) groups in various countries. Such forms of stigmatization can lead to delayed assessment and services for mental health among children and caregivers. This review identified the research literature on the types of stigmatization experienced by caregivers of children with autism with an EM background. A total of 19 studies published after 2010 (i.e., 12 from the USA, 2 from the UK, 1 from Canada, and 1 from New Zealand) of caregivers of 20 ethnicities were identified and reviewed, and their reporting qualities systematically also assessed. Four main themes: (1) self-stigma, (2) social stigma, (3) stigma towards EM parents of children on the autism spectrum, and (4) service utilization stigma, and nine sub-themes were identified. The discrimination experienced by caregivers were extracted, synthesized, and further discussed. While the reporting quality of the studies included is good, the depth of the understanding of this under-researched yet important phenomenon is very limited. The multiple forms of stigmatization experiences are complex, and it may be difficult to disentangle whether the causes of stigmatization were autism and/or EM related, and the types of stigmatization can vary enormously among different ethnic groups in different societies. More quantitative studies are needed to quantify the impacts of multiple forms of stigmatization on families of children with autism in EM groups so that more socially inclusive support for caregivers with an EM background in host countries can be developed.

Methotrexate and Non-Surgical Periodontal Treatment Change the Oral-Gut Microbiota in Rheumatoid Arthritis: A Prospective Cohort Study

This study evaluated the changes in the composition of oral-gut microbiota in patients with rheumatoid arthritis (RA) caused by methotrexate (MTX) and non-surgical periodontal treatment (NSPT). Assessments were performed at baseline (T0), 6 months after MTX treatment (T1), and 45 days after NSPT (T2). The composition of the oral and gut microbiota was assessed by amplifying the V4 region of the 16S gene from subgingival plaques and stools. The results of the analysis of continuous variables were presented descriptively and non-parametric tests and Spearman's correlation were adopted. A total of 37 patients (27 with periodontitis) were evaluated at T0; 32 patients (24 with periodontitis) at T1; and 28 patients (17 with periodontitis) at T2. MTX tended to reduce the alpha diversity of the oral-gut microbiota, while NSPT appeared to increase the number of different species of oral microbiota. MTX and NSPT influenced beta diversity in the oral microbiota. The relative abundance of oral microbiota was directly influenced by periodontal status. MTX did not affect the periodontal condition but modified the correlations that varied from weak to moderate (p < 0.05) between clinical parameters and the microbiota. MTX and NSPT directly affected the composition and richness of the oral-gut microbiota. However, MTX did not influence periodontal parameters.

Spiritual Well-being, Diabetes Burden, Self-management, and Glycemic Control Among Patients with Type 2 Diabetes in Turkey: A Descriptive and Correlational Study

Spiritual well-being is considered a significant factor in helping to manage chronic diseases and cope with the disease process. This descriptive-correlational study aimed to investigate the relationship between spiritual well-being, diabetes burden, self-management, and among 300 outpatients with type 2 diabetes in Turkey. A significant relationship was found between the diabetes burden and self-management levels and the spiritual well-being of patients with diabetes (p < 0.005). Multiple linear regression analyses found that a high diabetes burden (ß = -0.106) decreased well-being, and high self-management increased well-being (ß = 0.415). Additionally, the results revealed that marital status, household members, performing daily life activities alone, hospitalization due to complications, diabetes burden, self-management, glycemic control, and blood lipid parameters explained 29% of the total variance in the spiritual well-being level. Accordingly, the present study recommended that health professionals should consider spiritual well-being to support disease management with a holistic approach to diabetes patients.

Poor regulation, desperation, and misinformation, a countrywide analysis of self-medication and prescription patterns in Ecuador during the COVID-19 pandemic

BACKGROUND

The rapid spread of the SARS-CoV-2 virus during the early phase of the pandemic led to an unprecedented global health crisis. Various factors have influenced self-medication practices among the general population and unsubstantiated prescribing practices among healthcare professionals.

OBJECTIVE

This study aimed to describe trends in the purchase and sale of medicines during the COVID-19 pandemic period (2020-2022) in Ecuador, by comparing them with pre-pandemic periods.

METHODS

In this study, a cross-sectional design was employed to conduct a comprehensive analysis of 28 pharmacological groups, categorized according to the Anatomical Therapeutic Chemical Classification (ATC). Utilizing an integrated drug consumption database, the study examined physician prescribing data, medicine usage, and spending levels in Ecuador during the COVID-19 pandemic. The analysis involved computing absolute differences in monthly resolution, calculating excessive expenditure in comparison to previous yearly averages, and using Defined Daily Dose (DDD) methodology for internationally comparable results. Furthermore, a correlation analysis was performed to investigate potential associations between prescribed and consumed medicines and the number of new cases and deaths.

RESULTS

In Ecuador, the average yearly expenditure among these groups prior to the pandemic (2017-2019) amounted to $150,646,206 USD, whereas during 2020 and 2021, the same groups represented a total expenditure of $228,327,210, reflecting a significant increase. The excess expenditure during this period reached 51.4%, equivalent to $77,681,004 USD. Notably, 13% of this expenditure consisted of Over the Counter (OTC) Medicines. The study also identified a remarkable surge in sales of ivermectin, which increased by 2,057%, and hydroxychloroquine, which increased by 171%, as measured by DDD.

CONCLUSIONS

This study highlights the substantial consumption of medicines by the population in Ecuador during the pandemic. It is concerning that many medications were sold without proven therapeutic indications, indicating that misinformation and desperation may have led to improper prescribing by physicians and patients resorting to ineffective drugs. Moreover, since the sale of these therapeutic drugs requires a prescription, poor regulation, and a lack of control within pharmacies likely contributed to such practices.

Predictors of older patients' willingness to have medications deprescribed: A cross-sectional study

BACKGROUND

Deprescribing is a complex process requiring a patient-centred approach. One frequently expressed deprescribing barrier is patients' attitudes and beliefs towards deprescribing. This study aimed to identify the predictors of patients' willingness to have medications deprescribed.

METHODS

A cross-sectional study was conducted with community-dwelling patients aged ≥65 who are taking at least one regular medication. Data collection included patients' demographic and clinical characteristics and the Portuguese revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire. Descriptive statistics were used to present the patients' characteristics. Multiple binary logistic regression analysis was performed to identify the predictors of the patients' willingness to have medications deprescribed.

RESULTS

One hundred ninety-two participants (median age 72 years; 65.6% female) were included. Most (83.33%) were willing to have medications deprescribed, and the predictors were age (adjusted odds ratio [aOR] = 1.136; 95% CI 1.026, 1.258), female sex (aOR = 3.036; 95% CI 1.059, 8.708) and the rPATD concerns about stopping factor (aOR = 0.391; 95% CI 0.203, 0.754).

CONCLUSIONS

Most patients were willing to have their medications deprescribed if it is recommended by their doctors. Older age and female sex increased the odds of willingness to deprescribe; higher concerns about stopping medications decreased the odds. These findings suggest that addressing patients' concerns about stopping their medicines may contribute to deprescribing success.

Disability-adjusted life years due to COVID-19 in Sri Lanka: a retrospective cross-sectional study

Objectives

To estimate the health burden of COVID-19 in Sri Lanka using disability-adjusted life years (DALYs) and to investigate how the burden varies across age groups and sex.

Methods and analysis

A retrospective study was conducted based on information obtained from the daily situation reports and monthly epidemiological reports issued by the Epidemiology Unit of the Ministry of Health, Sri Lanka. DALYs due to COVID-19 in Sri Lanka from 27 January 2020 to 30 June 2022 were estimated by age and sex. For the calculation, we also included the DALYs due to mild anxiety for the family members of the patients with COVID-19.

Results

The total number of COVID-19 cases reported during this time period was 664 123, of which, 54% were males. There were 16 521 deaths reported giving a case fatality rate of 2.48%, which was higher in females as compared with males. The total years of life lost during this period is estimated to be 77 679 for males and 115 065 for females. The estimate of DALYs due to COVID-19 in Sri Lanka was 269 606 corresponding to 12.2 per 1000 population.

Conclusion

Compared with other countries, the burden of COVID-19 in Sri Lanka, as assessed by DALYs, was relatively low. This may be due to the country being an island and the strict rules imposed by the government to limit the spread of the disease. Assessing the impact of COVID-19 using only DALYs does not reflect the devastating economic and social consequences experienced by the country.

Assessing the safety of deep sedation in outpatient pediatric oral health care

BACKGROUND

Children are the patient subgroup with the lowest error tolerance regarding deep sedation (DS)-supported care. This study assessed the safety of DS-supported pediatric dental treatment carried out in an outpatient setting through retrospective review of patient charts.

METHODS

An automated script was developed to identify charts of pediatric patients who underwent DS-supported dental procedures from 2017 through 2019 at a dental clinic. Charts were assessed for the presence of sedation-related adverse events (AEs). A panel of experts performed a second review and confirmed or refuted the designation of AE (by the first reviewer). AEs were classified with the Tracking and Reporting Outcomes of Procedural Sedation system.

RESULTS

Of the 175 DS cases, 19 AEs were identified in 15 cases (8.60%). Using the Tracking and Reporting Outcomes of Procedural Sedation classification system, 7 (36.84%) events were related to the airway and breathing category, 9 (47.37%) were related to sedation quality (including a dizzy patient who fell at the checkout desk and sustained a head laceration), and 3 (15.79%) were classified as an allergy.

CONCLUSION

This study suggests an AE (whether relatively minor or of potentially major consequence) occurs in 1 of every 12 DS cases involving pediatric patients, performed at an outpatient dental clinic. Larger studies are needed, in addition to root cause analyses.

PRACTICAL IMPLICATIONS

As dentists increasingly pivot in the use of DS services from in-hospital to outpatient settings, patients expect comparable levels of safety. This work helps generate evidence to drive targeted efforts to improve the safety and reliability of pediatric outpatient sedation.

Use of home and community-based services and loneliness in older people with functional limitations: a cross-sectional study

BACKGROUND

Loneliness is one of the major health problems among older adults. Among this population, home and community-based services (HCBS) have become increasingly popular. Despite its health benefits, little is known about the relationship between HCBS use and loneliness in older people with functional limitations. We aim to explore the characteristics of loneliness among older people with functional limitations and examine the association between HCBS use and loneliness in China.

METHODS

We used a cross-sectional data from the 2018 China Health and Retirement Longitudinal Study, which includes a nationally representative sample of Chinese residents aged 65 and older with functional limitations. Logistic regression models were used to examine the associations between HCBS use and loneliness, and we further used propensity score matching to address potential sample selection bias.

RESULT

In China, 46% of older people with functional limitations felt lonely and only 22% of older people with functional limitations reported using HCBS in 2018. Compared with participants who did not receive HCBS, those who received HCBS were less likely to report loneliness (OR = 0.81, 95% CI = 0.63, 0.99, p = 0.048), and the results remained significant after addressing sample selection bias using propensity score matching.

CONCLUSION

Our results showed that loneliness was common among Chinese older people with functional limitations, and the proportion of HCBS use was low. There was robust evidence to support that among older people with functional limitations, HCBS use was associated with decreased loneliness. Further policies should promote the development of broader HCBS use for older people with functional limitations to reduce their loneliness.

Leukemia/lymphoma oral infiltration and its impact on disease outcomes: A Brazilian study

OBJECTIVE

Oral malignant infiltrations (OMI) are relevant for the diagnosis and prognosis of leukemia/lymphoma. This study analysed the oral health status and OMI of individuals with leukemia/lymphoma.

MATERIALS AND METHODS

A retrospective analysis (2010-2021) of data from individuals seen at a specialized hospital-based dental service in Brazil.

RESULTS

A total of 781 cases of leukemia/lymphoma were surveyed. Acute lymphoblastic leukemia (30.1%), acute myeloid leukemia (AML; 26.0%), and non-Hodgkin lymphoma (22.2%) were the most common diagnoses. The first (21.3%) and second (19.3%) decades of life were the most affected. Overall, dental caries (36.7%) and periodontal changes (34.6%) were the most frequent oral conditions. OMI occurred in 25 (3.2%) individuals. Lesions mainly involved the gingiva (80%) and patients diagnosed with AML (64%). Death (p < 0.001) and worse periodontal condition (p = 0.036) were more frequent among adults with OMI than among those without OMI. Death (p = 0.002) was more frequent among paediatric individuals with OMI than among those without OMI. When controlling for underlying disease, no association was observed between OMI and these outcomes.

CONCLUSION

Oral status of individuals with leukemia, particularly those with acute leukemia or lymphoma, should be closely monitored since one or multiple conditions may occur, including OMI, which may influence disease outcomes.

Characterizing the Impact of Procedure Funding on the Covid-19 Generated Procedure Gap in Ontario: A Population-Based Analysis

BACKGROUND

Surgical procedures in Canada were historically funded through global hospital budgets. Activity-based funding models were developed to improve access, equity, timeliness, and value of care for priority areas. COVID-19 upended health priorities and resulted in unprecedented disruptions to surgical care, which created a significant procedure gap. We hypothesized that activity-based funding models influenced the magnitude and trajectory of this procedure gap.

METHODS

Population-based analysis of procedure rates comparing the pandemic (March 1, 2020-December 31, 2021) to a prepandemic baseline (January 1, 2017-February 29, 2020) in Ontario, Canada. Poisson generalized estimating equation models were used to predict expected rates in the pandemic based on the prepandemic baseline. Analyses were stratified by procedure type (outpatient, inpatient), body region, and funding category (activity-based funding programs vs. global budget).

RESULTS

In all, 281,328 fewer scheduled procedures were performed during the COVID-19 period compared with the prepandemic baseline (Rate Ratio 0.78; 95% CI 0.77-0.80). Inpatient procedures saw a larger reduction (24.8%) in volume compared with outpatient procedures (20.5%). An increase in the proportion of procedures funded through activity-based programs was seen during the pandemic (52%) relative to the prepandemic baseline (50%). Body systems funded predominantly through global hospital budgets (eg, gynecology, otologic surgery) saw the least months at or above baseline volumes, whereas those with multiple activity-based funding options (eg, musculoskeletal, abdominal) saw the most months at or above baseline volumes.

CONCLUSIONS

Those needing procedures funded through global hospital budgets may have been disproportionately disadvantaged by pandemic-related health care disruptions.

Using photon disinfection technologies for reducing bioburden in hospitals

BACKGROUND

Environmental cleaning and disinfection is the basis of the prevention of healthcare-acquired infections (HAIs).

AIM

This study aimed to describe photon disinfection technologies (PDTs), report their impact on inactivating micro-organisms and preventing HAIs and to create recommendations for their implementation in hospital settings.

METHODS

An integrated literature review was completed to evaluate and report the impact of PDTs in hospital settings. The quality of 23 articles were assessed, their contents analysed and results reported according to the PICOT model.

FINDINGS

The microbiological impact of the PDT varied by micro-organism, settings and according to the used devices. It was crucial that environmental cleaning was completed before the disinfection.

CONCLUSION

The implementation of PDT in the hospital setting requires inquiry from the viewpoints of microbiological, environmental, occupational, technical and human safety. To enhance the safe implementation of PDTs, the construction and use of evidence-based global standards for PDT are crucial.

A Systematic Review on Navigation Programs for Persons Living With Dementia and Their Caregivers

BACKGROUND AND OBJECTIVES

System navigation programs are becoming more available to meet the needs of patients with complex care needs. The aim of this review was to systematically assess the outcomes of navigation programs for persons with dementia and their family caregivers.

RESEARCH DESIGN AND METHODS

A systematic review methodology was employed. Ten databases were searched for all relevant articles published until October 30, 2021. English-language full-text articles were included if they focused on implemented navigation program(s) that primarily supported persons with dementia who were aged 50 or older. Methodological quality was assessed by 2 independent raters using the Physiotherapy Evidence Database Scale, the STrengthening the Reporting of OBservational studies in Epidemiology checklist, and the Mixed Methods Appraisal Tool.

RESULTS

Fourteen articles were included in the review. There was Level 1 evidence for the benefits of system navigation programs on delaying institutionalization, wherein benefits appeared to be specific to interventions that had an in-person component. There was Level 1 (n = 4) and Level 3 (n = 1) evidence on service use from time of diagnosis to continued management of dementia. Finally, Level 1 to Level 5 evidence indicated a number of benefits on caregiver outcomes.

DISCUSSION AND IMPLICATIONS

There is strong evidence on the benefits of system navigation for people with dementia on delaying institutionalization and caregiver outcomes, but outcomes across other domains (i.e., functional independence) are less clear, which may be due to the varied approaches within system navigation models of care.

Telehealth Use and Access to Neurology Outpatient Clinical Services for Children: An Observational Cohort Study

Background

Access to neurology services is important for children's well-being. We sought to evaluate the effects of telehealth on pedi-atric neurology appointment outcomes for children.

Methods

Using electronic health record (EHR) data, information about children with pediatric neurology appointments in a tertiary care children's hospital in North Carolina was collected. Appointment outcomes (completion, cancellation, and no-show rates) were calculated for children who had a neurology appointment scheduled both in the pre-pandemic (March 10, 2019, to March 9, 2020) and pandemic (March 10, 2020, to March 9, 2021) periods. "Telehealth user" was a child who had at least one telehealth appointment scheduled between March 10, 2020, and March 9, 2021. In bivariate and multivariate analyses, we compared appointment outcomes for telehealth users and non-users.

Limitations

EHR data were limited to a single institution and could have missed children's clinical encounters elsewhere. Since this study used secondary data that were not collected for research purposes, it is possible that there were unmeasured confounders. Because of the observational nature of the study, the association between telehealth use and appointment outcomes does not indicate causation.

Results

A total of 2110 children had 11,194 pediatric neurology appointments scheduled. Telehealth users compared with non-users were more likely to be White, non-Hispanic, have private insurance, and live farther from the children's hospital. There was a statistically sig-nificant decrease in completion (66% versus 57%) and increase in cancellation (27% versus 33%) and no-show (7% versus 10%) rates in the pandemic when compared to the pre-pandemic period. In the pre-pandemic period, telehealth user and non-user groups had similar cancellation and no-show rates. In the pandemic period, there was a statistically significant decrease in cancellation and no-show rates in the telehealth user group when compared to the non-user group.

Conclusions

Pediatric neurology outpatient clinic visits decreased substantially during the pandemic. Telehealth mitigated these problems. Children belonging to a minority race/ethnicity are less likely to use telehealth, increasing their risk of poor access to neurology services.

Adverse Reactions Associated with Dermal Fillers in the Oral and Maxillofacial Region: A Venezuelan Experience

BACKGROUND

Dermal facial fillers are increasingly popular. Published reports on the clinical and histopathologic characteristics related to adverse reactions to dermal fillers in the facial region have been relatively well documented. This study adds to the literature on adverse reactions to injected filler in the oral and maxillofacial region in a South American population.

METHODS

A retrospective, descriptive cross-sectional study (2019-2020) was performed. The study population was a dermatology service in Venezuela. Clinical and histopathologic features of patients with adverse effects were documented.

RESULTS

A total of 35 cases of adverse reactions associated with cosmetic filler procedures were diagnosed during the analyzed period; of these, six cases (17.1%) involved the oral and maxillofacial region. All cases occurred in women. The mean age at diagnosis was 59.3 years (58-73). In three cases, dermal fillers were used in different locations on the face, while three involved the lips. Five patients exhibited adverse reactions to lip filler. All six cases were histopathologically diagnosed as foreign body reactions to injected material. Four and two cases revealed microscopic features compatible with hyaluronic acid and polymethylmethacrylate, respectively.

CONCLUSION

Reflecting the dramatic increase in cosmetic procedures with soft tissue fillers, this study contributed by reporting six cases of foreign body reaction involving the oral and maxillofacial region, confirmed with biopsy and histopathology.

Antiseptic Techniques in Breast Implant Surgery: Insights From Plastic Surgeons in Saudi Arabia

Background

Breast implant surgery is a popular procedure worldwide, and the same holds true for Saudi Arabia. Ensuring a sterile surgical environment is crucial to avert postoperative infections. This study explores the various antiseptic techniques adopted by Saudi plastic surgeons during breast implant procedures.

Objectives

This study aims to assess Saudi plastic surgeons' adherence to antiseptic measures in breast implant surgery, and determine what types of antiseptic measures are most commonly used among Saudi plastic surgeons.

Methods

The authors conducted a cross-sectional survey among board-certified plastic surgeons in Saudi Arabia, collecting data through a self-administered online questionnaire. This questionnaire, which covered their demographic information and their antiseptic practices during breast implant surgery, was disseminated via a WhatsApp (Menlo Park, CA) broadcast message from May 15 to June 27, 2023.

Results

Of the 52 Saudi plastic surgeons who completed the questionnaire, all reported employing preoperative antibiotics and skin disinfection. Other measures included pocket irrigation (86.5%), implant irrigation (92.3%), sleeve/funnel usage (65.4%), nipple shield usage (51.9%), and glove change during the procedure (96.2%). Nearly, all respondents used only a surgical cap for head cover (96.2%) and postoperative antibiotics as prophylaxis (98.1%). However, more than half of them did not minimize door movement during the procedure (51.9%).

Conclusions

This study offers a valuable insight into the antiseptic practices during breast implant surgery in Saudi Arabia. The findings underline the need for further research to establish evidence-based guidelines for antiseptic practices in this field.

Level of Evidence 5

A critical spotlight on the paradigms of FFPE-DNA sequencing

In the late 19th century, formalin fixation with paraffin-embedding (FFPE) of tissues was developed as a fixation and conservation method and is still used to this day in routine clinical and pathological practice. The implementation of state-of-the-art nucleic acid sequencing technologies has sparked much interest for using historical FFPE samples stored in biobanks as they hold promise in extracting new information from these valuable samples. However, formalin fixation chemically modifies DNA, which potentially leads to incorrect sequences or misinterpretations in downstream processing and data analysis. Many publications have concentrated on one type of DNA damage, but few have addressed the complete spectrum of FFPE-DNA damage. Here, we review mitigation strategies in (I) pre-analytical sample quality control, (II) DNA repair treatments, (III) analytical sample preparation and (IV) bioinformatic analysis of FFPE-DNA. We then provide recommendations that are tested and illustrated with DNA from 13-year-old liver specimens, one FFPE preserved and one fresh frozen, applying target-enriched sequencing. Thus, we show how DNA damage can be compensated, even when using low quantities (50 ng) of fragmented FFPE-DNA (DNA integrity number 2.0) that cannot be amplified well (Q129 bp/Q41 bp = 5%). Finally, we provide a checklist called 'ERROR-FFPE-DNA' that summarises recommendations for the minimal information in publications required for assessing fitness-for-purpose and inter-study comparison when using FFPE samples.

The use of Traditional Medicines for Sexual Enhancement in Northern Nigeria

BACKGROUND

There is a paucity of information on the use of traditional medicine TM to improve sexual performance. This study aims to assess the prevalence and self-reported adverse effects associated with the use of TM as a sexual enhancer in northern Nigeria.

METHODS

The study was a cross-sectional design among adults aged 18 years and above, who are residing in northern Nigeria. A mixed-mode approach was utilized using face-to-face interviews and an online survey. For the online survey, a link to the questionnaire was shared on the social media platforms of the targeted participants.

RESULTS

A total of 794 eligible participants completed the survey over the six weeks. Of this number, 508 reported ever using TM for sexual enhancement, with a prevalence of 64% (95% CI: 60.5, 67.3). About 30 (3.8%) reported daily use, 49 (4.9%) weekly, 65 (8.2%) monthly and 473 (59.6%) as when needed. Islamic medicine was the most frequently implicated TM. Most respondents obtained it TM practitioners 213 (26.8%). Participants 164 (20.7%) reported experiencing side effects, mostly headaches 59 (35.9%), and 31 (3.9%) were severe (required hospitalization). Predictors of TM use for sexual enhancement were found to be gender, marital status, number of wives, ethnicity, educational level, and lifestyle.

CONCLUSION

The use of TM for sexual enhancement is common among the adult population in northern Nigeria. One out of five of the users reported an adverse event. Therefore, there is a need for improved awareness of the safe use of the TM in the community, especially among females, those with multiple wives, a low education level, and poor lifestyles.

Regional Implicit Racial Bias and Rates of Breast Reconstruction, Complications, and Cost Among US Patients With Breast Cancer

Importance

Racial disparities influencing breast reconstruction have been well-researched; however, the role of implicit racial bias remains unknown. An analysis of the disparities in care for patients with breast cancer may serve as a policy target to increase the access and quality of care for underserved populations.

Objective

To identify whether variations in implicit racial bias by region are associated with the differences in rates of immediate breast reconstruction, complications, and cost for White patients and patients from minoritized racial and ethnic groups.

Design, Setting, and Participants

This cohort study used data from the National Inpatient Sample (NIS) from 2009 to 2019. Adult female patients with a diagnosis of or genetic predisposition for breast cancer receiving immediate breast reconstruction at the time of mastectomy were included. Patients receiving both autologous free flap and implant-based reconstruction were included in this analysis. US Census Bureau data were extracted to compare rates of reconstruction proportionately. The Implicit Association Test (IAT) was used to classify whether implicit bias was associated with the primary outcome variables. Data were analyzed from April to November 2022.

Exposure

IAT score by US Census Bureau geographic region.

Main Outcomes and Measures

Variables of interest included demographic data, rate of reconstruction, complications (reconstruction-specific and systemic), inpatient cost, and IAT score by region. Spearman correlation was used to determine associations between implicit racial bias and the reconstruction utilization rate for White patients and patients from minoritized racial and ethnic groups. Two-sample t tests were used to analyze differences in utilization, complications, and cost between the 2 groups.

Results

A total of 52 115 patients were included in our sample: 38 487 were identified as White (mean [SD] age, 52.0 [0.7] years) and 13 628 were identified as minoritized race and ethnicity (American Indian, Asian, Black, and Hispanic patients and patients with another race or ethnicity; mean [SD] age, 49.7 [10.5] years). Implicit bias was not associated with disparities in breast reconstruction rates, complications, or cost. Nonetheless, the White-to-minoritized race and ethnicity utilization ratio differed among the regions studied. Specifically, the reconstruction ratio for White patients to patients with minoritized race and ethnicity was highest for the East South Central Division, which includes Alabama, Kentucky, Mississippi, and Tennessee (2.17), and lowest for the West South Central Division, which includes Arkansas, Louisiana, Oklahoma, and Texas (0.75).

Conclusions and Relevance

In this cohort study of patients with breast cancer, regional variation of implicit bias was not associated with differences in breast reconstruction utilization, complications, or cost. Regional disparities in utilization among racial and ethnic groups suggest that collaboration from individual institutions and national organizations is needed to develop robust data collection systems. Such systems could provide surgeons with a comparative view of their care. Additionally, collaboration with high-volume breast centers may help patients in low-resource settings receive the desired reconstruction for their breast cancer care, helping improve the utilization rate and quality of care.

Development of preoperative and postoperative machine learning models to predict the recurrence of huge hepatocellular carcinoma following surgical resection

Resection has been commonly utilized for treating huge hepatocellular carcinoma (HCC) with a diameter of ≥10 cm; however, a high rate of mortality is reported due to recurrence. The present study was designed to predict the recurrence following resection based on preoperative and postoperative machine learning models. In total, 1,082 patients with HCC who underwent liver resection in the Eastern Hepatobiliary Surgery Hospital cohort between January 2008 and December 2016 were divided into a training cohort and an internal validation cohort. In addition, 164 patients from Mengchao Hepatobiliary Hospital cohort between January 2014 and December 2016 served as an external validation cohort. The demographic information, and serological, MRI, and pathological data were obtained from each patient prior to and following surgery, followed by evaluating the model performance using the concordance index, time-dependent receiver operating characteristic curves, prediction error cures, and a calibration curve. A preoperative random survival forest (RSF) model and a postoperative RSF model were constructed based on the training set, which outperformed the conventional models, such as the Barcelona Clinic Liver Cancer (BCLC), the 8th edition of the American Joint Committee on Cancer (AJCC 8th) staging systems, and the Chinese stage systems. In addition, the preoperative and postoperative RSF models could also re-stratify patients with BCLC stage A/B/C or AJCC 8th stage IB/II/IIIA/IIIB or Chinese stage IB/IIA/IIB/IIIA into low-risk, intermediate-risk, and high-risk groups in the training and the two validation cohorts. The preoperative and postoperative RSF models were effective for predicting recurrence in patients with huge HCC following hepatectomy.

Management of oral leukoplakia with an 808-nm high-power diode laser: a single-center experience

PURPOSE

High-power diode laser emerges as a promising approach to the treatment of oral leukoplakia (OL); however, its short- and long-term effects have been barely explored. This study evaluated the postoperative endpoints and the recurrence rate of high-power diode laser treatment in a well-defined series of patients with OL.

METHODS

A prospective analysis was performed on 22 individuals comprising 31 OL. The lesions were irradiated using the following protocol: Indium-Gallium-Arsenide diode laser, 808 nm, continuous-wave mode, 1.5-2.0 W, 780.0 ± 225.1 J, and 477.1 ± 131.8 s. Postoperative pain was assessed with a visual analog scale at three endpoints. Clinical follow-up was performed on all patients and the Kaplan-Meier test was used to analyze the probability of recurrence.

RESULTS

The series consisted mostly of women (72.7%) with a mean age of 62.8 years. A single laser session was performed in 77.4% of cases. The median score on the scale that assessed pain on the 1st, 14th and 42nd postoperative day was 4, 1, and 0, respectively. The mean follow-up period per lesion was 28.6 months (range: 2-53 months). A complete response was observed in 93.5% of OL cases, while 6.5% had recurrence. The probability of recurrence at 39 months was 6.7%. No patient experienced malignant transformation.

CONCLUSION

High-power diode laser for the treatment of OL is safe and effective during the trans- and postoperative period. These findings represent an alternative approach to the management of OL, mainly because a low recurrence rate was observed.

What proportion of clinical prediction models make it to clinical practice? Protocol for a two-track follow-up study of prediction model development publications

INTRODUCTION

It is known that only a limited proportion of developed clinical prediction models (CPMs) are implemented and/or used in clinical practice. This may result in a large amount of research waste, even when considering that some CPMs may demonstrate poor performance. Cross-sectional estimates of the numbers of CPMs that have been developed, validated, evaluated for impact or utilized in practice, have been made in specific medical fields, but studies across multiple fields and studies following up the fate of CPMs are lacking.

METHODS AND ANALYSIS

We have conducted a systematic search for prediction model studies published between January 1995 and December 2020 using the Pubmed and Embase databases, applying a validated search strategy. Taking random samples for every calendar year, abstracts and articles were screened until a target of 100 CPM development studies were identified. Next, we will perform a forward citation search of the resulting CPM development article cohort to identify articles on external validation, impact assessment or implementation of those CPMs. We will also invite the authors of the development studies to complete an online survey to track implementation and clinical utilization of the CPMs.We will conduct a descriptive synthesis of the included studies, using data from the forward citation search and online survey to quantify the proportion of developed models that are validated, assessed for their impact, implemented and/or used in patient care. We will conduct time-to-event analysis using Kaplan-Meier plots.

ETHICS AND DISSEMINATION

No patient data are involved in the research. Most information will be extracted from published articles. We request written informed consent from the survey respondents. Results will be disseminated through publication in a peer-reviewed journal and presented at international conferences. OSF REGISTRATION: (https://osf.io/nj8s9).

Use and Influence of Social Media on the Private Practice of Plastic Surgeons in Saudi Arabia

Today, social media platforms are more popular than ever in Saudi Arabia. Despite the influence of social media on patients' decisions to undergo cosmetic surgery, it is still unclear how social media platforms affect the private practice of plastic surgeons around Saudi Arabia. This study aimed to assess Saudi plastic surgeons' use of social media and its impact on their practices.

Methods

The study was based on a self-administered questionnaire that was built on previous literature and distributed to practicing Saudi plastic surgeons. A survey consisting of 12 items was conducted to assess patterns of social media use and its impact on plastic surgery practice.

Results

This study included 61 participants. Thirty-four surgeons (55.7%) were using social media platforms in their practice. The use of social media was significantly different among surgeons with different levels of practice in cosmetic surgery (P = 0.004) and reconstructive surgery (P = 0.049). Social media presence was significantly more prevalent among surgeons in private practice (70.6%, P = 0.034). The use of social media in plastic surgery is overall positive for the field (60.7%).

Conclusions

Despite plastic surgeons' differing views on social media, its role within the field of plastic surgery is evidently on the rise. The use of social media is not equal across all practice types. Surgeons practicing in private hospitals and specializing in aesthetic surgery are more likely to view social media favorably and use it in their practice.
