Correlation between the Atherogenic Index of Plasma and Progression of Non-target Lesion Vascular Disease Following Percutaneous Coronary Intervention using Drug-eluting Stents.

To examine the correlation between Atherogenic Index of Plasma (AIP) levels and the progression of non-target lesion vascular disease following the deployment of Drug-eluting Stents (DES). We retrospectively enrolled patients who had undergone successful treatment for CAD with DES and subsequently underwent a coronary angiography follow-up at the Cardiology Department of Tianjin Third Central Hospital from January 2017 to July 2022. The annual change in Gensini Score (GS) was calculated according to two angiographic evaluations in order to assess the progression of non-target lesion vascular disease; a change greater than 1 indicated progression, while a change of 1 or less indicated stability. AIP was calculated according to serum lipid parameters. Multivariate Logistic regression model was used to evaluate the relationship between AIP level and progression of non-target coronary artery lesions. The ROC curve analysis was performed to evaluate the diagnostic value of AIP for coronary artery non-target lesion vascular disease progression. Out of the 344 patients who were monitored over a median duration of 1.2 years, 113 exhibited progression of non-target lesion vascular disease. Initially, baseline AIP levels were notably higher in the progression group compared to the non-progression group (0.30 [0.14, 0.43] vs. 0.11 [-0.06, 0.31]), and this difference remained significant during the follow-up period (0.19 [0.06, 0.34] vs. 0.11 [-0.06, 0.22]). Multivariate logistic regression revealed that AIP is an independent predictor for the progression of non-target lesion vascular disease following DES treatment. Individuals in the highest tertile of AIP faced a considerably elevated risk compared to those in the lowest tertile (OR = 4.88, 95% CI: 2.12-11.21, P < 0.001). Moreover, utilizing receiver operating characteristic curve analysis, a 0.15 AIP level cut-off was determined for diagnosing disease progression, with a sensitivity of 73.5% and specificity of 56.7%, and an area under the curve of 0.672 (95% CI: 0.613-0.731, P < 0.01). AIP significantly correlates with the progression of non-target lesion vascular disease among patients with coronary artery disease who have undergone DES treatment, establishing itself as an independent risk factor in addition to conventional predictors.

Drug resistance of tuberculosis patients at the makassar city community lung health center hospital: Case Study

Introduction: Drug-resistant tuberculosis (TB-RO) is still a health problem because of its rapid transmission with an increasing number of cases. Objective: This study aims to discover in-depth patient knowledge about tuberculosis and the family's role in treating drug-resistant tuberculosis patients. Methods: This research uses a qualitative case study approach with nine informants. The selection of informants was determined using a purposive sampling technique. Data collection was obtained through interviews and observations. Data analysis was carried out qualitatively. Result: The research shows that informants' knowledge about drug-resistant tuberculosis depends on their educational history. In contrast, informants with low educational backgrounds only know the term tuberculosis but do not know the causes and dangers of drug-resistant tuberculosis. Another thing that was found was that the family also played a role in the patient's treatment by providing support and encouragement for the informant during the treatment period. Conclusion: This research concludes that the informant's knowledge about tuberculosis plays an essential role in the occurrence of drug-resistant tuberculosis. The role of the family does not contribute to the occurrence of drug-resistant tuberculosis in the informant. It can be concluded that the earlier the age of menarche increases the risk of uterine myoma later in life. In contrast, slower menarche may be associated with a reduced risk of myomas. Other factors such as genetic, environmental, and lifestyle factors also influence the incidence of uterine myomas, but menarche age is one of the significant hormonal indicators of risk.

OrthoMortPred: Predicting one-year mortality following orthopedic hospitalization

ObjectivePredicting mortality risk following orthopedic surgery is crucial for informed decision-making and patient care. This study aims to develop and validate a machine learning model for predicting one-year mortality risk after orthopedic hospitalization and to create a personalized risk prediction tool for clinical use. MethodsWe analyzed data from 3,132 patients who underwent orthopedic procedures at the Central Lisbon University Hospital Center from 2021 to 2023. Using the LightGBM algorithm, we developed a predictive model incorporating various clinical and administrative variables. We employed SHAP (SHapley Additive exPlanations) values for model interpretation and created a personalized risk prediction tool for individual patient assessment. ResultsOur model achieved an accuracy of 93% and an area under the ROC curve of 0.93 for predicting one-year mortality. Notably, ’EMERGENCY ADMISSION DATE TIME’ emerged as the most influential predictor, followed by age and pre-operative days. The model demonstrated robust performance across different patient subgroups and outperformed traditional statistical methods. The personalized risk prediction tool provides clinicians with real-time, patient-specific risk assessments and insights into contributing factors. ConclusionOur study presents a highly accurate model for predicting one-year mortality following orthopedic hospitalization. The significance of ’EMERGENCY ADMISSION DATE TIME’ as the primary predictor highlights the importance of admission timing in patient outcomes. The accompanying personalized risk prediction tool offers a practical means of implementing this model in clinical settings, potentially improving risk stratification and patient care in orthopedic practice.

Recurrence and influencing factors of hepatitis B surface antigen seroclearance induced by peginterferon alpha-based regimens

BACKGROUND The long-term stability of hepatitis B surface antigen (HBsAg) seroclearance following peginterferon alpha (peg-IFN-α)-based therapy has not been extensively studied, leaving the full potential and limitations of this strategy unclear. AIM To assess HBsAg recurrence after seroclearance achieved by peg-IFN-α regimens. METHODS This prospective, multicenter, observational study was conducted from November 2015 to June 2021 at three Chinese hospitals: The Second Affiliated Hospital of Xi’an Jiaotong University, Ankang Central Hospital, and The Affiliated Hospital of Yan’an University. Participants who achieved HBsAg seroclearance following peg-IFN-α-based treatments were monitored every 4-12 weeks post-treatment for hepatitis B virus (HBV) markers, HBV DNA, and liver function. The primary outcome was HBV recurrence, defined as the reemergence of HBsAg, HBV DNA, or both, at least twice within 4-8 weeks of follow-up. RESULTS In total, 121 patients who achieved HBsAg seroclearance were enrolled. After a median follow-up of 84.0 (48.0, 132.0) weeks, four subjects were lost to follow-up. HBsAg recurrence was detected in 16 patients. The cumulative HBsAg recurrence rate in the intention-to-treat population was 15.2%. Multivariate logistic regression analysis demonstrated that consolidation time &lt; 12 weeks [odds ratio (OR) = 28.044, 95%CI: 4.525-173.791] and hepatitis B surface antibody disappearance during follow-up (OR = 46.445, 95%CI: 2.571-838.957) were strong predictors of HBsAg recurrence. HBV DNA positivity and decompensation of liver cirrhosis and hepatocellular carcinoma were not observed. CONCLUSION HBsAg seroclearance following peg-IFN-α treatment was durable over 84 weeks of follow-up with a cumulative recurrence rate of 15.2%.

Global and Community Health: Neurologic Care and a Case Study for Immigrants and Refugees in West Philadelphia.

Philadelphia is a diverse city that has experienced an increasing immigrant and refugee population in recent decades. Although many academic medical centers also call Philadelphia their home, lack of accessibility and difficulty with insurance limit access to health care for many of its newest residents. The Social Health and Medical Services (SHAMS) Free Health Clinic was started to help address some of these disparities, especially for immigrant and refugee populations. Despite initial setbacks, the clinic has thrived and even moved locations to accommodate increasing patient demand. While many patients initially presented for primary care, there was a growing need for specialist care and coordinated multidisciplinary management. We present an example of a partnership between an academic center (Hospital of the University of Pennsylvania) and a community health center (SHAMS clinic), whereby patients have access to a dedicated neurology clinic that is run by residents and staffed by neurology attendings. This has allowed patients to have access to outpatient neurologic care, has facilitated referral to inpatient care when needed for serious conditions such as status epilepticus (as in the case study discussed), and has allowed for continuity of care between the hospital and the outpatient setting. Although this clinic is an endeavor to create an academic-community partnership, there is still much work to do to improve medical access in the immigrant and refugee communities.

Effect of Intensive Nursing Management on Quality of Life and Mental Health in Elderly Gastric Cancer Patients Undergoing Chemotherapy: A Retrospective Study

Aims/Background Implementing effective nursing management is particularly critical in the case of elderly gastric cancer (GC) patients receiving chemotherapy, who are more vulnerable to risk events. Therefore, this study explored the effect of intensive nursing management on quality of life (QoL) and mental health in elderly GC patients receiving chemotherapy. Methods A total of 155 elderly patients with GC undergoing chemotherapy in Central Hospital Affiliated to Shandong First Medical University from July 2021 to July 2023 were selected as the study subjects. The sample was divided into two groups according to different nursing methods: 74 patients who received intensive nursing management were classified in the observation group, while 81 patients treated with routine nursing management were classified under the reference group. The QoL, mental health and adverse reactions to chemotherapy were compared between the two groups. Results Before nursing management was implemented, there was no significant difference in the scores of the quality of life questionnaire-core 30 (QLQ-C30), patient health questionnaire-9 items (PHQ-9), and the Chinese version of the M.D. Anderson Symptom Inventory (MDASI-C) (p &gt; 0.05). After management, in comparison with the reference group, the observation group showed significantly higher scores in each dimension of QLQ-C30, as well as significantly lower scores in PHQ-9 and MDASI-C (p &lt; 0.001). The incidences of gastrointestinal reaction, myelosuppression, neurotoxicity, and hepatorenal damage were lower in the observation group than in the reference group (45.95% vs 70.37%, 40.54% vs 65.43%, 35.14% vs 53.09%, and 33.78% vs 51.25%, respectively; p &lt; 0.05). Conclusion The application of intensive nursing management in treating elderly GC patients during chemotherapy effectively improves their physical and mental states, ameliorates clinical symptoms and enhances the QoL, showing certain clinical application value.

Sexually transmitted infections in sexually abused children: an audit project to implement PCR tests in a child advocacy center in Türkiye

Background. Sexual abuse in children can sometimes result in sexually transmitted infections (STIs), which can serve as crucial forensic evidence. Although PCR methods are now accepted as the gold standard for STI screening, they have not yet widely replaced traditional culture methods in Türkiye. This study aims to assess the necessity of implementing PCR-based STI testing at Child Advocacy Centers in Türkiye, where such testing is not routinely available. Methods. Conducted between February and November 2023, this study included children who presented to the Child Advocacy Center of Marmara University Pendik Training and Research Hospital. High-risk victims were identified based on criteria including a history of penetrative sexual abuse and factors such as multiple perpetrators or significant age disparity. Serological tests and genital swabs were collected and analyzed using both bacterial culture methods and a comprehensive STI PCR panel. Results. The study included 20 victims, with a median age of 16 years. STI PCR testing detected pathogens in 19 out of 21 samples, including Chlamydia trachomatis (20%) and Neisseria gonorrhoeae (5%). In contrast, culture methods identified no sexually transmitted pathogens. Conclusion. PCR testing demonstrated significantly higher sensitivity for detecting STIs compared to traditional bacterial culture methods, as expected. Implementing PCR-based STI testing in Child Advocacy Centers is an urgent and essential need for providing an accurate diagnosis and robust forensic evidence, enhancing the care and legal protection of sexually abused children.

A Longitudinal Study of the Association of Awareness of Disease Incurability with Patient-Reported Outcomes in Heart Failure.

To examine awareness of disease incurability among patients with heart failure over 24 mo and its associations with patient characteristics and patient-reported outcomes (distress, emotional, and spiritual well-being). This study analyzed 24-mo data from a prospective cohort study of 251 patients with heart failure (New York Heart Association class III/IV) recruited from inpatient wards in Singapore General Hospital and National Heart Centre Singapore. Patients were asked to report if their doctor told them they were receiving treatment to cure their condition. "No" responses were categorized as being aware of disease incurability, while "Yes" and "Uncertain" were categorized as being unaware and being uncertain about disease incurability, respectively. We used mixed-effects multinomial logistic regression to investigate the associations between awareness of disease incurability and patient characteristics and mixed-effects linear regressions to investigate associations with patient outcomes. The percentage of patients who were aware of disease incurability increased from 51.6% at baseline to 76.4% at 24-mo follow-up (P < 0.001). Compared with being unaware of disease incurability, being aware was associated with older age (relative risk ratio [RRR] = 1.04; P = 0.005), adequate self-care confidence (RRR = 5.06; P < 0.001), participation in treatment decision making (RRR = 2.13; P = 0.006), higher education (RRR = 2.00; P = 0.033), financial difficulty (RRR = 1.18; P = 0.020), symptom burden (RRR = 1.08; P = 0.001), and ethnicity (P < 0.05). Compared with being unaware of disease incurability, being aware was associated with higher emotional well-being (β = 0.76; P = 0.024), while being uncertain about disease incurability was associated with poorer spiritual well-being (β = -3.16; P = 0.006). Our findings support the importance of being aware of disease incurability, addressing uncertainty around disease incurability among patients with heart failure, and helping patients make informed medical decisions. The findings are important to Asian and other cultures where the prognosis disclosure to terminally ill patients is generally low with an intention to "protect" patients. Our 24-mo study with heart failure patients showed an increase from 52% to 76% in patients being aware of disease incurability.Compared with being unaware of disease incurability, being aware was associated with higher emotional well-being, while uncertainty about disease incurability was associated with poorer spiritual well-being.

A pedicled anterolateral thigh flap decreased the risk of empty pelvis syndrome following total pelvic exenteration.

Total pelvic exenteration (TPE) can be complicated by empty pelvis syndrome (EPS), and none of the currently available procedures completely mitigate this problem. The aim of this study was to evaluate the feasibility and effectiveness of a pedicled anterolateral thigh (p-ALT) flap for preventing EPS. All cases of TPE at the National Cancer Center Hospital in Tokyo between 2008 and 2022 were retrospectively reviewed. The main indication for TPE was colorectal cancer, with some other malignancies. Background factors, surgical outcomes and postoperative complications were compared between patients who underwent primary suture closure (the PC group) and those who underwent p-ALT flap reconstruction (the flap group). A total of 114 patients underwent TPE during the study period. Twenty patients in whom a different procedure was performed or a different flap was used for reconstruction were excluded, leaving 94 for analysis (PC group, n = 54; flap group, n = 40). There was no significant between-group difference in patient characteristics. Severe pelvic abscess developed in 12 patients (22.2%) in the PC group and 2 (5%) in the flap group. Multivariable analysis identified a significantly lower risk of severe pelvic abscess in the p-ALT flap reconstruction (OR 0.07, 95% CI 0.01-0.58, p = 0.01). EPS-related readmissions were more common in the PC group [37.0% (20/54) vs. 25% (10/40)]. The risk of severe pelvic abscesses and readmission for EPS was significantly lower after perineal reconstruction with a p-ALT flap. Perineal reconstruction with this flap is a feasible and effective method in TPE.

A Cardiac Tumor and Liver Masses on Point of Care Ultrasound (POCUS): Implications in a Resource-Limited Setting

Malignant cardiac tumors are quite rare, but portend a poor prognosis [1,2]. Early identification and classification are essential given their aggressive nature, particularly when metastases are present [3,4]. Clinical presentations are varied, and detection relies primarily on echocardiography. Thus, cardiac tumors may go undiagnosed in areas where echocardiography is not routinely available [1,5]. In this case, point of care ultrasound (POCUS) rapidly detected a cardiac mass and liver lesions, prompting referral to a central hospital in Malawi for further evaluation. This case highlighted the potential role of POCUS as a readily available tool in a resource-limited setting, serving as a triage point for more definitive diagnosis and management [6-8].

Analysis of wrong blood in tube events at a hospital-based blood centre in a tertiary care referral hospital: A perspective from a lower middle-income country.

Wrong blood in tube (WBIT) continues to be a preventable cause of unintended harm to the patient. The literature describing extent of the problem, its consequences and factors leading to WBIT from the perspective of lower middle-income countries (LMICs) is limited. The present study describes WBIT and its outcome in a hospital-based blood centre from an LMIC. WBIT events occurring during the study period were analysed to identify the root cause. In addition, they were analysed according to discipline, department and time of sample draw. Root causes were divided and compared with standard operating procedure (SOP) for sample collection for blood requests. All WBIT events were followed and their outcomes analysed. WBIT events occurred at a rate of 4.8/10,000 blood requests, with a higher rate in urgent requests (5.2/10,000 requests). The average rate of WBIT was higher in surgical disciplines compared to medical and acute care services (6.58 vs. 4.43 vs. 3/10,000 requests). The highest rate of WBIT was observed when requests were received during 8:00 PM-2:00 AM (p = 0.02). Deviations from SOP with contribution from human and organizational elements were identified as the root cause. The consequences ranged from delay in providing blood to acute haemolytic transfusion reactions. We found that WBITs occurred at a rate comparable to that reported from developed countries. Use of software and automation may reduce the rate of WBIT but not eliminate it completely. Strict adherence to SOPs and continuous training of phlebotomy staff would help reduce it to a minimum. Blood centres need to develop specific strategies with respect to their root causes.

REMEMBER: 30 YEARS SINCE CONSTANTIN ARSENI PASSED AWAY - THE FONDATOR OF ROMANIAN NEUROSURGERY

Introduction The authors will present one of the great personalities of Romanian neurosurgery, Dr Constantin Arseni, who created it in Bucharest, creating the largest university centre of neurosurgery in Europe at that time. Material After the tragic loss of his mentor Prof. Dr Dumitru Bagdasar in 1946, Dr Constantin Arseni, took over the management of the neurosurgery service at the Central Hospital for Mental, Nervous and Endocrinologic Diseases, the only department of this kind in this country; He was able to have the first Clinic of Neurosurgery from Romania. For his merits, Dr Constantin Arseni, became an Associate Professor in 1952 and University Professor in 1963. His neurosurgical activity was complex, but mainly focused on tumoral pathology, cerebral and spinal, and also on spinal degenerative disease. Under Professor C. Arseni, the Neurosurgical Clinic of Bucharest is transformed in 1975 into the “Prof. Dr D. Bagdasar” Clinical Hospital of Neurosurgery, the largest hospital of Neurosurgery in the Europe, with 550 beds and, subsequently, 650 beds. Also, he developed the departments of neurosurgery in each of the biggest university centres in the country; while being the first President of the Romanian Society of Neurosurgery. Scientific Activity Scientific activity of Prof. Dr Constantin Arseni includes the numerous publications (54 treaties and monographies), together with all his collaborators, encompassing all domains of neurosurgery: Tumoral, Neuropathological, Vascular, Paediatric, Spinal Degenerative Pathology, Central Nervous System Malformations, History, etc. with high international visibility. An editorial board under C. Arseni published, with the substantial contribution of the Bucharest Medical Publishing House of the Clinic, the “Treatise of Neurology” in 8 volumes (1979-1981). Conclusions Professor Constantin Arseni was a dedicated surgeon, he practiced his job asking from those around him as much as he offered - the maximum. He was a schoolmaster and a teacher in the true sense of word. Professor Constantin Arseni, Member of the Romanian Academy, was an exemplary professional, a model of conduct, which will forever remain in our memory, of the neurosurgeons, and of the Romanian neurosurgery, leaving behind a legacy hard to match for those who followed him.

Cerebral venous sinus thrombosis and exploration of prognostic factors: a case series

BackgroundThis study examined the etiology, treatment response, and prognosis of patients with cerebral venous sinus thrombosis (CVST) at a single institution.MethodsThis retrospective study included patients diagnosed with CVST between January 2016 and December 2020 at Baotou Central Hospital. The data were collected from patient charts, including sex, age, comorbidities, pregnancy, smoking, alcohol drinking, symptoms at onset, radiological location, examinations, Glasgow coma scale (GCS) at admission, National Institutes of Health stroke scale (NIHSS) at admission, modified Rankin scale (mRS) at admission, and treatments.ResultsThe study included 31 patients (13 males and 18 females) aged 39.0 (interquartile range, 30.0–53.0) years. Three (9.7%) patients had a history of hypertension, one (3.2%) had a history of stroke, four (12.9%) had thrombotic disorders, six (19.4%) were pregnant (including three who delivered), four (12.9%) were smoking, and four (12.9%) were drinking alcohol. The GCS at admission was 15.0 (IQR, 15.0–15.0), the NIHSS at admission was 0.0 (IQR, 0.0–2.0), and the mRS at admission was 0.0 (IQR, 0.0–0.0). The patients were grouped according to their mRS (&amp;gt;0 vs. 0); there were no significant differences between the two groups regarding the patient characteristics (all p &amp;gt; 0.05). Only an NIHSS of &amp;gt;0 at follow-up was associated with a 3-month mRS &amp;gt;0 (p &amp;lt; 0.001).ConclusionThe median age of the patients with CVST was 39 years. The majority were female (58%), 13% had thrombotic disorders, and 19% were or were recently pregnant. Only a NIHSS of &amp;gt;0 at follow-up was associated with a 3-month mRS &amp;gt;0.

MS O02 - OGC An audit of waiting times of the oesophagogastric cancer diagnostic pathway at a high-volume, tertiary centre

Abstract Background The oesophagogastric cancer (OGC) staging pathway is extensive, contributing to prolonged waiting times from referral to treatment. NHS England guidance details the ideal timeframe from referral to finalisation of the patient’s treatment plan and stipulates a time of 21 days from OGD to communication of the treatment plan to the patient. This audit aims to compare pathway times at a tertiary cancer centre, which accepts referrals from seven different hospitals, to the current NHS target and further stratify pathway times according to patient characteristics and referring hospitals. Method Data was collected using a prospectively collected database of OGC patients who underwent staging investigations at the tertiary centre between October 2022 and October 2023. The primary outcome was OGD to communication of the treatment plan. Secondary outcomes included time from OGD to first staging investigation and the proportion of patients that had a next-day computed tomography (CT) scan. Outcomes were stratified to investigate inter-hospital variation and the effect of curative status and tumour location. Data was expressed as median and interquartile range (IQR) for continuous data or n (%) if categorical. Results 263 patients were included in this audit with a median age of 69.0 (IQR 61.5-77.0). 13.8% of patients satisfied the target time of 21 days from OGD to communication of treatment plan. Curative patients had a longer median pathway time than palliative patients (49.0 vs 35.0 days), whereas oesophageal and gastric cancer patients had similar pathway times (44.0 vs 44.5 days). Patients diagnosed at the tertiary centre had a faster time from OGD to first staging investigation than patients diagnosed at non-specialist centres. Only 13.3% of patients had a next-day CT scan following their OGD (median time 5.0 days). Conclusion The OGC staging pathway is considerably slower than the target. Faster pathway times in palliative patients can be attributed to many of these patients not requiring further staging post-CT. Potentially, targets should be re-evaluated to distinguish between palliative and curative patients. The faster staging process at the central hospital may be explained by more regular clinics run by specialist clinicians and the prompt requesting of staging investigations without awaiting MDT discussions. Alongside increasing the proportion of next-day CT scans, these factors must be addressed to streamline the entire pathway.

Genomic sequencing and neutralizing serological profiles during acute dengue infection: A 2017 cohort study in Nepal.

Dengue virus (DENV) is a mosquito-borne flavivirus that poses a threat to nearly 50% of the global population. DENV has been endemic in Nepal since 2006; however, little is known about how DENV is evolving or the prevalence of anti-DENV immunity within the Nepalese population. To begin to address these gaps, we performed a serologic and genetic study of 49 patients from across Nepal who presented at central hospitals during the 2017 dengue season with suspected DENV infection. Of the 49 subjects assessed, 21 (43%) were positive for DENV NS1 antigen; of these; 5 were also anti-DENV IgM+ IgG+; 7 were DENV IgM+ IgG-, 2 were IgM- IgG+, and 7 were IgM-IgG- by specific ELISAs. Seven of the 21 NS1 positive sera were RNA positive by RT-PCR (six DENV2, one DENV3), suggesting that DENV2 was the dominant serotype in our cohort. Whole-genome sequencing of two DENV2 isolates showed similarity with strains circulating in Singapore in 2016, and the envelope genes were also similar to strains circulating in India in 2017. DENV-neutralizing antibodies (nAbs) were present in 31 of 47 sera tested (66%); among these, 20, 24, 26, and 12 sera contained nAbs against DENV1, 2, 3, and 4 serotypes, respectively. Additionally, 27 (58%) samples had nAbs against multiple serotypes (2 or more). Serology analysis suggested that 12 (26%) and 19 (40%) of the 47 subjects were experiencing primary and secondary DENV infections, respectively. Collectively, our results provide evidence for current and/or past exposure to multiple DENV serotypes in our cohort. These data suggest that expanded local surveillance of circulating DENV genotypes and population immunity will be important to effectively manage and mitigate future dengue outbreaks in Nepal.

Data managers and clinical research coordinators: a tool to collect the hourly activity

Background and Aims: the main purpose of this paper is analyzing the hourly activities performed by Data Managers (DMs) and Clinical Research Coordinators (CRCs) in a Clinical Trial Center (CTC) of an Italian Public Hospital in order to define and monitor the relevant job descriptions of these professionals Materials and Methods: the CTC of the Research and Innovation Departments (DAIRI) has created a tool to collect the hourly activity of DMs and CRCs. In the period between January 1 and December 31, 2022; the activities were collected and grouped in 24 macro areas. Results: the main activities conducted by staff are found in the macro areas "Study Management" (15.78%); "Briefing/Planning" (12.86%) and “Data Management/Data Entry” (12.42%). A difference was found between the activities carried out by CRCs and those conducted by DMs. Conclusions: the results of this monitoring, compared with data obtained at the national level, confirm the heterogeneity of the tasks performed by these professional figures. These differences increasingly underscore the need to obtain recognition of the figure by the National Health System (NHS) with the definition of a precise “job description”.

Assessment of patient knowledge and perceptions towards orthodontic treatment in the Aljouf Region, Saudi Arabia: a cross-sectional study

Background In orthodontic treatment, it is most important to assess the patient’s perspective of malocclusion because these perceptions are fundamental to determining the patient’s demands and level of treatment satisfaction. This study was done to assess the knowledge and perception of residents of the Aljouf Region of Saudi Arabia seeking orthodontic treatment. Furthermore, we determined the factors associated with the patients’ knowledge and perception of orthodontic treatment. Methods This cross-sectional study was conducted using a pre-tested and validated questionnaire among patients seeking orthodontic treatment who were registered at King Abdulaziz Hospital, Sakaka, and primary health centers. We identified the associated factors using binomial logistic regression analysis. Finally, we applied Spearman’s correlation test to identify the correlation between knowledge and perception. Results A total of 282 individuals participated in the current study, of which 53.3% were female and 46.1% were male. About one-third (36.9%) of patients had a low level of knowledge, 35.5% had a medium level of knowledge, and 27.7% had a high level of knowledge regarding orthodontic treatment. A total of 20.6% had low perceptions, 42.9% had medium perceptions, and 36.5% had high perceptions of orthodontic care. A significant correlation was found between age and gender, knowledge (p = 0.001), and perception (p = 0.040). Moreover, we observed a positive correlation between knowledge and perception (Spearman’s rho = 0.297, p = 0.001). Conclusion People in Aljouf have poor knowledge and medium perception regarding orthodontic treatment. We recommend that the concerned authorities make a health educational plan for the patients seeking orthodontic treatment.
