Process Evaluation of a Pilot Food Insecurity Resource Navigation Program Integrated Within Pediatric Primary Care: Utilizing RE-AIM to Inform Program Scale-up

Objective: The purpose of this study was to examine the implementation and effectiveness of a novel pediatric food navigation program through a structured, comprehensive evaluation using the RE-AIM framework. Design and Participants: Data were collected from October 2021 through August 2022 for 166 pediatric patients and their families who were screened as food insecure or high-risk for food insecurity and were referred to this pilot food resource navigation program (FRNP). A total of 88 patients’ guardians consented to participate in this FRNP, receiving initial service connection. Participants were contacted via telephone by trained navigators within this health system to assess food security status across three time points (baseline, follow-up 1 [1- <3 months], and follow-up 2 [3-6 months]) and facilitate connection to appropriate community-based resources related to food assistance. Results: In this sample, we had an overrepresentation of Hispanic patients and an underrepresentation of Non-Hispanic Black and White patients relative to the available clinic population. Patients participating in the navigation program showed incremental shifts toward food security from baseline to two follow-up points. Integration within primary care was supported by physician champions across participating clinics and alignment with systemwide, updated universal screening guidelines to support projected increases in families requiring connecting to assistance programs. Through this evaluation, a comprehensive list of community-based food resource programs related to food assistance was integrated into electronic documentation for navigators to alleviate navigator burden and sustain the effect of this FRNP’s implementation. Conclusions: These findings may be used to inform expansion of current programming efforts within this FRNP and to clarify process evaluations of broader health system-based programming. Further research, building on the findings of this pilot study, is needed to examine the longitudinal, causal effect of FRNPs in pediatric food security and long-term health outcomes for replication across health systems nationwide.

Short-term safety and effectiveness of conversion from sleeve gastrectomy to Ring augmented Roux-en-Y gastric bypass

BackgroundWeight recurrence, suboptimal clinical response and functional disorder (such as reflux) after a Sleeve Gastrectomy (SG) are problems that may require conversional surgery. For reflux, conversion to Roux-en-Y Gastric Bypass (RYGB) is considered effective. Regarding treatment for suboptimal clinical response, the technique of choice remains a subject of debate. This study aims to evaluate the safety and effectiveness of conversion from SG to Ring-augmented RYGB ( RaRYGB).MethodsAll laparoscopic SG to RaRYGB conversions performed between January 2016 and January 2022 were included. Primary outcome was percentage total weight loss (%TWL) after 1-year follow-up. Secondary outcomes consisted of cumulative %TWL, complications (with a focus on ring-related complications), and resolution of medical-associated problems.ResultsWe included 50 patients of whom 44 were female. Mean pre-conversion BMI was 37.6 kg/m2. All patients have reached the 1-year follow-up point, however 10 were lost to follow-up. After 1-year mean TWL was 17.8% while mean cumulative TWL, calculated from primary SG, was 32%. A total of 10 complications occurred in 8 patients within 30 days, 6 of which were ≤ CD3a and 4 ≥ CD3b. One MiniMizer was removed for complaints of severe dysphagia. Of the 35 medical-associated problems present at screening 5 remained unchanged(14.2%), 15 improved(42.9%) and 15 achieved remission(42.9%).ConclusionOur series of 50 patients undergoing conversion from SG to RaRYGB is adequate and successful regarding additional weight loss 1 year after conversion, cumulative weight loss, complication rate and achievement of improvement or remission of medical-associated problems.

The therapeutic effect of PCSK9 inhibitors on dyslipidemia: one-year follow up.

Despite the availability of statins and lifestyle modifications, many patients with Dyslipidemia struggle to achieve optimal low-density lipoprotein cholesterol (LDL-C) control. PCSK9 inhibitors offer a promising new therapeutic option with superior LDL-C lowering efficacy compared to statins. However, data on their real-world use, particularly in Iran, is limited. This study aims to address this gap by investigating the one-year effects of evolocumab on lipid profiles and potential cardiovascular outcomes in Iranian patients with Familial Hypercholesterolemia (FH).This single-center, prospective study evaluated evolocumab effectiveness in lowering LDL-C in 50 Iranian adults with FH. Participants with a documented LDL-C > 190 mg/dL on existing cholesterol medications (excluding PCSK9 inhibitors) and a clinical FH diagnosis was included. After baseline assessments (medical history, demographics, lipid profile), evolocumab was administered subcutaneously every two weeks for one year. Follow-up assessments at year one measured changes in LDL-C, high-density lipoprotein cholesterol (HDL-C), and triglycerides. The study enrolled 50 participants with an average age of 55 years old (range 35-80 years).Treatment with evolocumab led to significant improvements in lipid profiles at all follow-up points compared to baseline. On average, LDL-C levels decreased by 105.24 mg/dL, triglycerides decreased by 59.20 mg/dL, and HDL-C levels increased by a modest but significant 4.5 mg/dL after one year(p<0.001). Subgroup analysis revealed no statistically significant interactions between baseline demographics (age, sex, BMI) or lifestyle habits (smoking, alcohol) and changes in lipid levels(p>0.05). However, a significant interaction emerged between baseline lipid levels and their corresponding reductions, suggesting greater improvement in patients with higher baseline values(p<0.05). It is noteworthy that no new cardiovascular events were reported during the study period. This study demonstrates the effectiveness of evolocumab in improving lipid profiles in Iranian patients with FH. The observed reductions in LDL-C and triglycerides, along with a modest increase in HDL-C, suggest potential benefits for cardiovascular risk reduction. The absence of new cardiovascular events during the study is encouraging, but further research with larger and longer-term follow-up is needed to confirm these findings and assess the long-term safety and impact on quality of life.

The effectiveness of a disaster preparedness educational intervention for wheelchair users: A pilot study

ObjectiveThis pilot study aimed to test the effectiveness of disaster preparedness education for wheelchair users and improve their self-management skills during emergencies. MethodsA pre-post self-controlled experimental study was conducted. The intervention included one educational session covering the following: (1) Knowledge about local frequent disasters,. (2) Development of a tailored disaster preparedness plan for wheelchair users. (3) Preparation of a disaster kit. The methods included lectures, discussions, and scenario responses to disasters. Disaster preparedness knowledge, attitudes, and behaviors were assessed before, after and one month follw-up intervention. Results20 wheelchair users with average age of 41.2 ± 7.68. Most of them reported proficiency in wheelchair using. The educational intervention significantly improved knowledge and attitude scores post-intervention, with knowledge scores rising from 8.00 ± 2.25 to 13.85 ± 0.37 and attitude scores from 47.05 ± 6.45 to 52.30 ± 3.87. At the one-month follow-up, there was a slight regression in knowledge(11.00 ± 1.65) and attitude scores(50.70 ± 3.94) but still significantly higher than pre-intervention levels. Behavior scores were assessed only at pre and follow-up measurement points, with an increasing trend from 3.60 ± 1.93 to 8.60 ± 2.89, indicating sustained improvement in disaster preparedness behaviors. The study highlights the need for sustainable intervention methods due to the observed decline in knowledge retention and attitude over time. ConclusionThe tailored disaster preparedness education for wheelchair users significantly improved their knowledge, fostered positive attitudes, and encouraged proactive behaviors in response to disasters. To sustain these positive outcomes, ongoing educational reinforcement and periodic updates are essential, especially for vulnerable populations like wheelchair users.

P191 CO-EXISTING HYPERTENSION: AN INDEPENDENT RISK FACTOR FOR DIABETIC RETINOPATHY IN TYPE-2 DIABETES

Background and Objectives: Hypertension has plausible reason to be show the interaction due to its independent effect on retina. Epidemiological studies also provide clue that for hypertension as a possible effect modifier in the risk development of retinopathy in diabetic patients. It is worth exploring whether subgroup in diabetic population with Hypertension have different risk potential of developing retinopathy. The present study aimed to assess the association of hypertension as a risk factor for diabetic retinopathy (DR) in type 2 diabetes mellitus. Methods: A total of 977 type-2 diabetic patients recruited retrospectively in 2008 from Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorder (BIRDEM) based on hospital records for determining the incidence of diabetic retinopathy (DR), who were naı̈ve type-2 diabetes during 1993. At the end of 15 year follow-up 495 patients were diagnosed as DR by retinal colour photography. Data on diabetes and lipid profile with serum creatinine, blood pressure and biophysical measures were obtained at baseline, 5, 10 and 15 years follow-up. Binary logistic regression model was used to assess the associations of co-existing hypertension with retinopathy risk adjusting for clinical, biochemical and anthropometric variables. Results: In all three follow-up points, including at baseline, mean systolic and diastolic blood pressure were found to significantly higher among patients who developed DR (P&lt;.001). Binary logistic regression model confirmed coexisting hypertension (OR 3.2; 95% CI 2.2 -4.7) as a significant risk factor of DR adjusting for possible confounders; serum creatinine (OR 21.9; 95% CI 14.0 -35.4) and glycemic control status (OR 17.2; 95% CI 9.4 -31.4). Interaction between hypertension, glycemic control and raised serum creatinine did not appear to be statistically significant (P&gt;0.05). Conclusions: Co-existing hypertension is a significant risk factor of DR irrespective of nephropathy or glycolic control status among Type 2 diabetes mellitus.

The Association of Conventional Therapy Associated with Somatosensory Interactive Game Enhances the Effects of Early Pulmonary Rehabilitation for Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial.

Objective: This study aimed to evaluate the effect of somatosensory interactive games in combination with pulmonary rehabilitation programs (PRPs) on exercise tolerance, balance function, pulmonary function, inflammatory markers, and healthcare utilization in individuals with acute exacerbation of chronic obstructive pulmonary disease over 12 months. Design: In a randomized controlled trial, 80 patients were divided into two groups. The control group participated in a lasted 30 minutes daily program composed of postural training for 10 minutes, limb movement for 10 minutes, and breathing exercises for 10 minutes based on regular oxygen therapy and medication. The experimental group received a once-daily, 20-minute somatosensory interactive game session based on the control group. Patients began treatment within 48 hours after admission and lasted for 6 weeks. Results: The time × group interactions on 6-minute walk distance (6MWD) and Brief Balance Evaluation Systems Test (Brief-BESTest) between the two groups were significant (P < 0.001). At the postintervention and each time point of follow-up, the 6-minute walk distance (6MWD) and Brief-BESTest of the intervention group were significantly higher than those of the control group (P < 0.05). The effects of time factor on forced expiratory volume in one second and forced vital capacity were statistically significant (P < 0.05). The 6MWD and Brief-BESTest of the intervention group peaked 3 months after the intervention and were higher than the control group within 12 months. C-reactive protein and procalcitonin were similar between the groups before and after intervention (P > 0.05). The readmission rates and mean length of time spent in the hospital were comparable between the groups at 12 months (P > 0.05). Conclusions: The addition of somatosensory interactive games based on a PRP was safe and feasible, and this benefit persisted for 12 months, peaked at 3 months after the intervention, and then gradually decreased.

Clinical effectiveness of amlodipine/indapamide/perindopril fixed-dose combination in patients with metabolic disorders: results of post hoc analyzes of the TRICOLOR study

Aim. To describe antihypertensive effectiveness of triple fixed-dose combination of am lo dipine/indapamide/perindopril and assess predictors of its clinical effectiveness in pati ents depending on body mass index (BMI) and presence of type 2 diabetes (T2D).Material and methods. This observational prospective study TRICOLOR (NCT03722524) (n=1247) demonstrated high antihypertensive effectiveness and good tolerability of amlodipine/indapamide/perindopril fixed-dose combination. Subgroup analyzes based on BMI included data from 1144 patients. In a second subgroup analysis, 1128 patients were stratified according to concomitant T2D.Results. In patients with overweight/obesity and diabetes, good antihypertensive effectiveness of amlodipine/indapamide/perindopril was observed, comparable in blood pressure (BP) reduction with the comparison groups (patients with normal BMI and patients without diabetes). At the same time, patients with normal BMI, compared with patients with overweight and obesity, had significantly lower systolic BP (SBP) (after 4 and 12 weeks) and diastolic BP (DBP) (after 2 and 12 weeks). In the subgroups, depending on the diabetes status, there were no significant differences in the decrease in SBP and DBP levels at all follow-up points. By the 12th week, BP decrease in the group of patients with normal BMI was 32,9 (10,5)/15,3 (8,6) mm Hg, in the group with overweight — 33,2 (11,3)/14,2 (8,5) mm Hg, in the obesity group — 33,9 (12,3)/14,1 (8,8) mm Hg (p&gt;0,05 for intergroup comparison). Target BP &lt;140/90 mm Hg already after 2 weeks of therapy achieved a higher number of patients with a normal BMI compared to overweight group (50,8% vs 37,2%, p=0,009). By the 12th week, the vast majority of patients, regardless of BMI and diabetes status, achieved a target BP &lt;140/90 mm Hg, which demonstrates a good and rapid response to triple fixed-dose therapy.Conclusion. Thus, additional analyzes of the TRICOLOR study demonstrate the high antihypertensive effectiveness of amlodipine/indapamide/perindopril in hypertensive patients, regardless of the presence of diabetes, overweight or obesity.

Efficacy and Safety of Shi Cervical Rotational Manipulation in Patients With Atlantoaxial Joint Subluxation: Protocol for a Randomized Controlled Trial.

The clinical diagnosis of atlantoaxial joint subluxation (AJS) in traditional Chinese medicine (TCM) is characterized by an unequal distance between the lateral mass of the atlas and the odontoid process on imaging, resulting in neck pain accompanied by symptoms such as dizziness, headache, and limited cervical mobility. In Shanghai, Shi cervical rotational manipulation (SCRM) is a commonly employed TCM manual therapy for treating this condition. Nevertheless, there is a lack of evidence-based medical information regarding the clinical efficacy and safety of this technique. The principal aim of this study is to evaluate the efficacy and safety of SCRM in patients diagnosed with AJS. This study is a prospective randomized controlled clinical trial that will be conducted at a single center and that has a follow-up period of 24 weeks. A total of 96 patients diagnosed with AJS will be recruited from outpatient and inpatient clinics at Shanghai Baoshan Hospital of Integrated Traditional Chinese and Western Medicine. These patients will be randomly assigned to either the experimental group (SCRM) or the comparison group (basic cervical manipulation [BCM]). Treatment sessions consisting of SCRM or BCM will be administered twice a week for a duration of 4 weeks. Clinical monitoring indicators include the presence or absence of clinical symptoms as recorded on a symptom recording form, cervical imaging examination findings using cervical computed tomography, degree of neck pain measured by a visual analog scale (VAS), cervical range of motion assessed through cervical mobility measurement, degree of vertigo evaluated using the Vertigo Symptoms Scale-Chinese Version (VSS-C), and adverse events that may occur during the follow-up period. The time points for data collection and follow-up are baseline and postintervention (weeks 4, 8, 12, 16, 20, and 24). This paper presents an overview of the reasoning and structure of a prospective randomized controlled trial with the objective of investigating the clinical efficacy and safety of SCRM in patients with AJS by assessing improvements in clinical symptoms, neck pain severity, and vertigo severity and evaluating changes in cervical imaging findings. Recruitment was started in March 2023. By the end of May 2024, 76 patients were included in this project. The last follow-up data are predicted to be collected by the end of February 2025. This investigation will yield dependable evidence regarding the efficacy and safety of SCRM in patients with AJS.

Nasal high flow or noninvasive ventilation? navigating hypercapnic COPD exacerbation treatment: A randomized noninferiority clinical trial

BackgroundNoninvasive ventilation (NIV) has been the cornerstone for managing acute exacerbations of COPD (AECOPD) with hypercapnic respiratory failure. Nasal high flow (NHF) oxygen therapy has emerged as a potential alternative, offering a more tolerable modality with promising outcomes. The aim of the present study was to evaluate whether NHF respiratory support is noninferior to NIV with respect to treatment failure, in patients with mild-to-moderate hypercapnic AECOPD. MethodsIn this multi-center, randomized, noninferiority trial, 105 patients with AECOPD and respiratory failure type II were enrolled. Participants were randomly assigned to receive either NHF therapy or NIV. The primary endpoint was the frequency of treatment failure, defined as the need for intubation and invasive mechanical ventilation or a switch to the alternative treatment group. Secondary endpoints included changes in respiratory parameters, patient comfort indicators, and the occurrence of complications. ResultsThe findings revealed no significant difference in the primary outcome between the groups, with a treatment failure rate of 19.6 % (10 out of 51) in the NHF group and 14.8 % (8 out of 54) in the NIV group. Interestingly, NHF users reported significantly lower levels of dyspnea and discomfort at multiple follow-up points. Despite the differences in patient comfort, respiratory parameters such as respiratory rate, arterial blood gases, and use of accessory muscles of respiration showed no significant disparities between the groups throughout the study period. ConclusionsNHF therapy was similar to NIV in preventing treatment failure among patients with hypercapnic AECOPD, offering a viable alternative with enhanced comfort. Trial registrationThe study was prospectively registered in ClinicalTrials.gov (Identifier: NCT03466385) on March 15, 2018.

Meibography signal intensity as a novel image biomarker for meibomian gland function: evidence from cross-sectional and longitudinal analyses.

Meibomian gland dysfunction (MGD), one of the most common ocular surface diseases, can induce dry eye and reduce patients' quality of life. Methodological limitations have resulted in contradictory interpretations of gland function. This study sought to investigate the correlation between meibography signal intensity (SI) and meibomian gland (MG) function and to validate an MGD classification strategy based on different levels of SI. A multicenter, cross-sectional analysis was conducted on 817 eyes from 361 patients with MGD and 52 healthy controls. Additionally, 78 eyes from 39 patients with MGD who had undergone LipiFlow treatment were recruited for longitudinal analyses. The SI value was obtained via meibography using an automated analyzer, and all participants underwent ocular surface examinations. A cross-sectional analysis was performed to determine SI distribution and its relationship to clinical characteristics via a generalized estimating equation model. Longitudinal analyses were conducted on the treatment cohort using a mixed-effects model to explore the outcome in different SI levels. Regression analysis revealed significant correlations between SI and lipid layer thickness (β=0.016), meibum expressibility (β=-0.676), meibum quality (β=-0.251), and fluorescein-stained tear-film break-up time (FBUT) (β=0.064) (all P values <0.001 for the above associations). Low-level SI MGD cases exhibited the most severe clinical signs, including the worst meibum expressibility (16% for level 3) and quality scores (19% for level 3), the shortest FBUT (3.82±0.13 s), and the thinnest lipid layer (65.68±2.58 nm), (all P values <0.05, respectively). Patients with medium SI showed the lowest ocular surface disease index (OSDI) value (26.64±1.06), the longest FBUT (4.56±0.08 s), and the thickest lipid layer (80.20±2.90 nm). After treatment, the high SI values reduced significantly at each follow-up point compared to baseline (all P values <0.05). The medium SI group demonstrated the greatest improvement in symptoms and signs, followed by the high SI group, and the low SI group. Automated measurements of SI can effectively reflect MG secretory activity. The proposed low, medium, and high SI classifications represent different functional subtypes of MGD.

Imaging characteristics and surgical effect for symmetrical lumbar hemivertebrae

Objective: To analyze the imaging characteristics and surgical effect for symmetrical lumbar hemivertebrae in pediatric patients. Methods: The data of 13 patients with hemivertebrae locating in the lumbar spine symmetrically were retrospectively analyzed, and all the patients were treated in Beijing Children's Hospital from January 2015 to September 2021. The mean age of the patients was 6.2 (2.9, 9.3) years. There were 8 males and 5 females. The data of coronal/sagittal plane including segmental Cobb angle, cranial/caudal compensatory curve, thoracic kyphosis, thoracolumbar kyphosis, sacral obliquity, and lumbar lordosis were recorded through long cassette spinal radiographs. Associated anomalies and the relationship between hemivertebrae and posterior component were recorded through computerized tomography (CT) and magnetic resonance imaging (MRI). All the patients received surgery, and their pre-and postoperative imaging data were compared. Results: A total of 26 hemivertebraes were found, in which 80.8% (21/26) located below L2. Hemivertebraes in 10 patients were separated by a mean 1-2 normal vertebrae. Most hemivertebraes along with the corresponding posterior component were unison (21/26, 80.8%). The Cobb angles of cranial compensatory curve (13.9°±7.2°) was more serious than that of caudal compensatory curve (5.5°±5.0°)(P=0.04). The lumbar lordosis and thoracic kyphosis was 20.2°±15.0° and 18.7°±9.2°, respectively. Six patients complicated with sacral obliquity, while 7 patients complicated with thoracolumbar lordosis. Associated anomalies were found in 6 (46.2%) patients through CT and MRI. Eleven patients received one-or two-stage posterior hemivertebrae resection with short segmental fusion, and 2 patients received one-stage hemivertebrae resection with long segmental fusion. All the surgery were completed successfully without serious complications such as nerve injury, infection, and implant failure. The mean follow-up period was (42.4±10.2) months. At the last follow-up point, the correction rate of segmental Cobb angle and cranial compensatory curve was 83.3%±15.6% and 38.1%±10.4%, respectively, showing significant improvement (P<0.05). Although the caudal compensatory curve, sacral obliquity, and thoracic kyphosis improved after surgery, the data showed no significant difference compared to that before surgery. Thoracolumbar lordosis in all patients were corrected. Conclusions: Most hemivertebraes in such spinal deformity locate in lower lumbar region with a high incidence of anomalies. Individualized treatment based on patients' condition is essential for the complicated spinal deformity.

Web-Based Warfarin Management (Alfalfa App) Versus Traditional Warfarin Management: Multicenter Prospective Cohort Study.

Poor anticoagulation management of warfarin may lead to patient admission, prolonged hospital stays, and even death due to anticoagulation-related adverse events. Traditional non-web-based outpatient clinics struggle to provide ideal anticoagulation management services for patients, and there is a need to explore a safer, more effective, and more convenient mode of warfarin management. This study aimed to compare differences in the quality of anticoagulation management and clinical adverse events between a web-based management model (via a smartphone app) and the conventional non-web-based outpatient management model. This study is a prospective cohort research that includes multiple national centers. Patients meeting the nadir criteria were split into a web-based management group using the Alfalfa app or a non-web-based management group with traditional outpatient management, and they were then monitored for a 6-month follow-up period to collect coagulation test results and clinical events. The effectiveness and safety of the 2 management models were assessed by the following indicators: time in therapeutic range (TTR), bleeding events, thromboembolic events, all-cause mortality events, cumulative event rates, and the distribution of the international normalized ratio (INR). This national multicenter cohort study enrolled 522 patients between June 2019 and May 2021, with 519 (99%) patients reaching the follow-up end point, including 260 (50%) in the non-web-based management group and 259 (50%) in the web-based management group. There were no observable differences in baseline characteristics between the 2 patient groups. The web-based management group had a significantly higher TTR than the non-web-based management group (82.4% vs 71.6%, P<.001), and a higher proportion of patients received effective anticoagulation management (81.2% vs 63.5%, P<.001). The incidence of minor bleeding events in the non-web-based management group was significantly higher than that in the web-based management group (12.1% vs 6.6%, P=.048). Between the 2 groups, there was no statistically significant difference in the incidence of severe bleeding and thromboembolic and all-cause death events. In addition, compared with the non-web-based management group, the web-based management group had a lower proportion of INR in the extreme subtreatment range (17.6% vs 21.3%) and severe supertreatment range (0% vs 0.8%) and a higher proportion in the treatment range (50.4% vs 43.1%), with statistical significance. Compared with traditional non-web-based outpatient management, web-based management via the Alfalfa app may be more beneficial because it can enhance patient anticoagulation management quality, lower the frequency of small bleeding events, and improve INR distribution.

Transarterial Embolization of Geniculate Arteries Reduces Pain and Improves Physical Function in Knee Osteoarthritis-A Prospective Cohort Study.

Knee osteoarthritis (OA) affects millions worldwide, leading to pain and reduced quality of life. Conventional treatments often fail to provide adequate relief, necessitating new therapeutic approaches. This study evaluated the efficacy and safety of genicular artery embolization (GAE) using permanent microspheres in patients with mild-to-moderate knee OA. In this prospective, single-center study, 17 participants underwent GAE. KOOS (Knee injury and Osteoarthritis Outcome Score), WOMAC (The Western Ontario and McMaster Universities Arthritis Index), and IPAQ (International Physical Activity Questionnaire) scores, along with physical performance tests, medication use, and dual-energy X-ray absorptiometry (DEXA) scans, were assessed at baseline and at multiple follow-up points over six months. The primary endpoint, VAS at six months, showed significant improvement (median reduction from 66 mm to 40 mm, p = 0.0004). All pain and function scores, as well as physical performance tests, improved significantly. No clinically relevant changes in medication use or DEXA parameters were observed after six months. Only minor, self-limiting adverse events occurred. This study indicates that GAE is a promising minimally invasive treatment for knee OA, providing significant pain relief and functional improvement. However, further long-term, randomized trials are needed to confirm these findings and establish optimal patient selection criteria.

Delayed effects of alcohol consumption on the association between serum BDNF levels and post-traumatic stress disorder development over two-years

BackgroundsThis study aimed to examine the individual and combined effects of serum BDNF (sBDNF) levels and alcohol consumption status, assessed shortly after a physical injury, on the development of post-traumatic stress disorder (PTSD) over two years. MethodsParticipants were consecutively recruited from a trauma center and followed prospectively for two years. At baseline, sBDNF levels and alcohol consumption history were assessed. A range of socio-demographic and clinical covariates were also collected. PTSD diagnosis during follow-up (3, 6, 12, and 24 months post-injury) was established using the Clinician-Administered PTSD Scale for DSM-5. Binary and multinomial logistic regression analyses were employed to investigate the relationships between sBDNF levels, alcohol consumption status, and PTSD onset. ResultsOut of 923 participants analyzed, 112 (12.1%) developed PTSD at some point during the study, with prevalence rates of 8.8% at 3 months, 7.6% at 6 months, 4.8% at 12 months, and 3.7% at 24 months. The study found no individual associations between sBDNF levels or alcohol consumption status and PTSD development. However, lower sBDNF levels significantly predicted PTSD in individuals who consumed alcohol, a relationship not observed in non-drinkers, with significant interaction terms. This pattern was consistent at later follow-up points from 12 to 24 months, but not at earlier assessments at 3 and 6 months. LimitationsThe study's reliance on participants from a single trauma center with moderate to severe injuries may limit the generalizability of the findings. ConclusionsA significant interaction between sBDNF levels and alcohol consumption in relation to PTSD development was observed, particularly in the long term. These findings highlight the necessity of considering both sBDNF levels and alcohol consumption in strategies aimed at preventing PTSD among individuals with physical injuries, underscoring the need for tailored approaches based on these factors.

Arthroscopic surgery for injuries to the popliteal tendon area of the lateral meniscus

To investigate the mid-term effect and complications of arthroscopic popliteal tendon suture in the treatment of lateral meniscus injury. From January 2016 to December 2020, the data of 57 patients with lateral meniscus popliteal tendon injury treated by arthroscopic popliteal tendon suture fixation were retrospectively analyzed, including 35 males and 22 females, aged from 18 to 47 years old with an average of (32.9±7.9) years old. Knee function was evaluated using the International Knee Documentation Committee (IKDC) and Lysholm scores both before the operation and at the final follow-up. Meniscus healing was evaluated according to the postoperative Barrett standard. Wound healing complications, such as vascular injury, nerve injury, and lower extremity venous thrombosis, were recorded. All 57 patients were followed up for 12 to 58 months with an average of (38.1±14.9) months.The incisions of the patients after the operation were all Grade A healing without infection, popliteal tendon injury, blood vessel injury, nerve injury and lower extremity venous thrombosis.The IKDC score increased from (49.7±3.6) points preoperatively to (88.5±4.4) points in the final follow-up (P<0.05). The Lysholm score increased from (48.8±4.9) points preoperatively to (91.9±3.9) points at the final follow-up (P<0.05). At 3, 6 months and 1 year after operation, according to Barrett's criteria, 54 cases were clinically healed, the healing rate was 94.7% (54/57). This study preliminarily confirmed that arthroscopic suture technique can result in clinical stability through suture and fixation of the meniscus in the injured lateral popliteal tendon area. No adverse effects on knee joint function were found in the mid-term follow-up after the operation.

Healthcare workers’ knowledge, attitude and practices on infection prevention and control in the context of the COVID-19 pandemic at the Faranah regional hospital and associated healthcare centers, Guinea

BackgroundIn response to the COVID-19 pandemic, WHO launched a strategic preparedness and response plan, outlining public health measures to support countries worldwide. Healthcare workers have an increased risk of becoming infected and their behaviour regarding infection prevention and control (IPC) influences infection dynamics. IPC strategies are important across the globe, but even more in low-resource settings where capacities for testing and treatment are limited. Our study aimed to assess and implement COVID-19 pandemic preparedness and response measures in Faranah, Guinea, primarily focusing on healthcare workers’ IPC knowledge, attitude and practice (KAP).MethodsThe study was conducted between April 2020 and April 2021 assessing IPC pandemic preparedness and response measures such as healthcare workers’ KAP, alcohol-based handrub (ABHR) consumption and COVID-19 triaging in the Faranah Regional Hospital and two associated healthcare centres. The assessment was accompanied by IPC training and visual workplace reminders and done in pre- and post- phases to evaluate possible impact of these IPC activities.ResultsThe overall knowledge score in the Faranah Regional Hospital was 32.0 out of 44 at baseline, and did not change in the first, but increased significantly by 3.0 points in the second follow-up. The healthcare workers felt closer proximity to SARS-CoV-2 overtime in addition to higher stress levels in all study sites. There was significant improvement across the observed triaging practices. Hand hygiene compliance showed a significant increase across study sites leading to 80% in Faranah Regional Hospital and 63% in healthcare centers. The average consumption of ABHR per consultation was 3.29 mL with a peak in February 2020 of 23 mL.ConclusionDespite increased stress levels among HCWs, the ongoing IPC partnership well prepared the FRH in terms of triaging processes with a stronger impact on IPC practice than on theoretical knowledge. Throughout the pandemic, global shortages and surges in consumption did not affect the continuous ABHR provision of the FRH. This highlights local ABHR production as a key pandemic preparedness strategy.

NATURAL COURSE OF AGE-RELATED RETENTIONAL AVASCULAR PIGMENT EPITHELIAL DETACHMENT: Support For The Lipid Barrier Hypothesis.

Retentional pigment epithelial detachment (PED) associated with age-related scattered hypofluorescent spots on late-phase indocyanine green angiography (ASHS-LIA) is hypothesized to be caused by Bruch membrane's lipid barrier. This study aimed to report the natural course of retentional PED and evaluate the relationship between retentional PED evolution and ASHS-LIA. Patients with treatment-naïve retentional PED were enrolled and observed every 3 months for at least 12 months. Treatment was not performed except for secondary macular neovascularization. In 55 studied eyes with a median follow-up of 18.0 (range: 12-36) months, 87.3% (48/55) of the retentional PEDs persisted, 7.3% (4/55) resolved, and 5.5% (3/55) progressed to polypoidal choroidal vasculopathy. The mean PED area significantly increased during the follow-up ( P < 0.001) and with the ASHS-LIA grade at each follow-up point (all P <0.05), especially during the first 6 months before approaching the edge of confluent ASHS-LIA. Persistent PEDs were mostly stable (52.1%) or enlarged (45.8%) but reduced in only 1 case (2.1%) because of retinal pigment epithelium microrip at the edge of PED. The persistent PEDs were all within the ASHS-LIA region, especially the macular confluence region. The resolved PEDs all had grade 1 ASHS-LIA and resolved after gradual expansion of PED beyond the confluent ASHS-LIA region. Pigment epithelial detachments that progressed to macular neovascularization all had confluent grade 2 or 3 ASHS-LIA. Retinal pigment epithelium microrips or apertures within PED did not affect the progression of the PED. The natural course of retentional PED is closely related to the features of ASHS-LIA and supports its lipid-barrier hypothesis.

Impact of concentrated growth factor (CGF) injection on acceleration of orthodontic tooth movement in rabbits

BackgroundThe present study aimed to assess how a concentrated growth factor (CGF) injection affects the rate of orthodontic tooth movement in rabbits.MethodsThis experimental investigation employed a split-mouth configuration. Before orthodontic mesialization of the maxillary first molars, CGF was prepared and administered using submucosal injections on the buccal and palatal sides of the maxillary first molars in one randomly assigned quadrant. The opposite quadrant was used as a control. The study examined four time points:1, 2, 3, and 4 weeks. The measurement of tooth movement was conducted at each follow-up point using a digital caliper. The rabbits were euthanized, and their maxillary segments, specifically the maxillary first molars, were studied histologically to identify any alterations occurring on both the tension and compression sides.ResultsSignificant tooth movement was observed in the experimental sides versus control sides in the second, third, and fourth week of follow-up periods (p ≤ 0.05). Histologically, on the compression side, the CGF group showed bone resorption and periodontal ligament active reactions from the first week and continued throughout the next three weeks. Also, on the tension side, the CGF group depicted cementoblastic and osteoblastic activities from the first week followed by fibroblastic activities from the second week and all activities continued till the fourth week.ConclusionsCGF has the potential to effectively enhance orthodontic tooth movement without adverse clinical or histological effects.

Polygenic hazard score predicts synaptic and axonal degeneration and cognitive decline in Alzheimer's disease continuum

BackgroundGrowth associated protein-43 (GAP-43) and neurofilaments light (NFL) are biomarkers of synaptic and axonal injury, and are associated with cognitive decline in Alzheimer's disease (AD) contiuum. We investigated whether Polygenic Hazard Score (PHS) is associated with specific biomarkers and cognitive measures, and if it can predict the relationship between GAP-43, NFL, and cognitive decline in AD. MethodWe enrolled 646 subjects: 93 with AD, 350 with mild cognitive impairment (MCI), and 203 cognitively normal controls. Variables included GAP-43, plasma NFL, and PHS. A PHS of 0.21 or higher was considered high risk while a PHS below this threshold was considered low risk. A subsample of 190 patients with MCI with four years of follow-up cognitive assessments were selected for longitudinal analysis . We assessed the association of the PHS with AD biomarkers and cognitive measures, as well as the predictive power of PHS on cognitive decline and the conversion of MCI to AD. ResultsPHS showed high diagnostic accuracy in distinguishing AD, MCI, and controls. At each follow-up point, high risk MCI patients showed higher level of cognitive impairment compared to the low risk group. GAP-43 correlated with all follow-up cognitive tests in high risk MCI patients which was not detected in low risk MCI patients. Moreover, high risk MCI patients progressed to dementia more rapidly compared to low risk patients. ConclusionPHS can predict cognitive decline and impacts the relationship between neurodegenerative biomarkers and cognitive impairment in AD contiuum. Categorizing patients based on PHS can improve the prediction of cognitive outcomes and disease progression.

Comparative Study of Laparoscopic Sleeve Gastrectomy With or Without Jejunal Bypass.

We evaluated the weight loss effect of laparoscopic sleeve gastrectomy (LSG) and jejunal bypass (JJB) in treating obesity by analyzing and comparing the effects of LSG with or without JJB. A retrospective analysis was performed on the data of 150 patients with obesity who underwent bariatric metabolic surgery in Affiliated Xiaolan Hospital,Southern Medical University from October 2014 to April 2019. The patients were divided into two groups, LSG and LSG + JJB, according to the different surgical methods. The differences in the percentage of excess weight loss (%EWL) and total weight loss (TWL) between the two groups were statistically analyzed. The %EWL of the patients in the LSG group reached the maximum value at one year and six months post-surgery and steadily decreased after two years post-surgery. In contrast, the %EWL of the patients in the LSG + JJB group gradually increased after two years post-surgery; however, no significant difference between the two groups was observed. The TWL in the LSG + JJB group was significantly greater than that in the LSG group at each follow-up point. Postoperative %EWL was similar in both groups. The TWL in the LSG + JJB group was greater than that in the LSG group, and the postoperative recurrent weight gain rate in the LSG + JJB group was lower than that in the LSG group.
