ABSTRACT

OBJECTIVE: This study aimed to expand knowledge and develop a list of technical assistance needs related to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) online shopping for small, tribal, and rural vendors; farmers; and farmers’ markets.

DESIGN: A modified Delphi method was used, collecting information via a web-based survey, facilitated workshops, a listening session, and individual interviews from October 2023 to February 2024.

SETTING: Surveys were distributed through Qualtrics. Zoom was used to conduct virtual workshops, a listening session, and individual interviews.

PARTICIPANTS: Purposive sampling techniques were used to recruit the study sample. Of the 435 invited, 239 completed 50% of the survey; 22 survey respondents attended the workshop; 3 tribal vendors and/or farmers attended interview sessions; and 5 non-WIC-authorized vendors, farmers, and farmers’ markets attended the listening session.

MAIN OUTCOME MEASURE(S): The overall phenomenon of interest included themes related to facilitators and barriers to WIC online shopping.

ANALYSIS: Statistical software was used to report descriptive statistics. A rapid qualitative analysis inductive approach was used to construct themes for the study.

RESULTS: Facilitators included support and guidance, a robust platform, and feedback mechanisms, whereas barriers included time, resources, and technology.

CONCLUSIONS AND IMPLICATIONS: To ensure WIC online shopping success, it is essential to address both the barriers and facilitators experienced by vendors, farmers, and farmers’ markets. While this study collected various perspectives and experiences from merchants, future research may also focus attention on WIC participant perceptions of shopping online with these food retailers.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the diagnostic ability of relative values of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion kurtosis imaging (DKI) quantitative parameters for salivary gland tumors (SGTs).

METHODS: A total of 107 patients with histopathologically confirmed SGTs (18 malignant [MTs], 38 pleomorphic adenomas [PAs], 31 Warthin tumors [WTs], 20 basal cell adenomas [BCAs]) underwent MRI with DKI and DCE-MRI sequences. Quantitative parameters included DCE-MRI-derived volume transfer constant (Ktrans), rate constant (Kep), fractional volume of the extravascular-extracellular space (Ve), plasma fraction (Vp), and DKI-derived mean kurtosis (MK) and mean diffusion (MD).The receiver operating characteristic (ROC) curve were used for statistical analysis. Statistical significance was set at P < 0.05.

RESULTS: PAs exhibited the lowest MK (0.49 ± 0.15) among all groups (P < 0.05). Compared to WTs, PAs showed lower Kep (366.89[260.06, 568.32]×10-³ min-1), higher MD (2.02 ± 0.42 × 10-³ mm2/s), and higher Ve (551.83[388.10, 883.19]×10-³). PAs also displayed higher Ve, lower Kep, and lower Vp (85.42[20.53, 332.72])×10-³) than BCAs, and lower Vp with higher Ve than MTs (all P < 0.05). WTs had significantly lower Ve (218.86[142.07, 341.76]×10-³) than MTs (P = 0.001). BCAs demonstrated lower MK (0.61 ± 0.23) and higher MD (1.97 ± 0.44 × 10-³ mm2/s) compared to WTs and MTs (P < 0.05), alongside lower Ktrans (355.25[211.88, 506.92]×10-³ min-1) and Ve (380.89[271.28, 589.53]×10-³) than WTs (P < 0.05). Logistic regression analysis revealed enhanced discrimination: MK+Ve (AUC = 0.895) and MK+MD+Ve+Kep (AUC = 0.936) differentiated PAs from WTs; Kep+Vp+Ve distinguished PAs from BCAs (AUC = 0.843); MD+MK+Vp separated PAs from MTs (AUC = 0.854); Ktrans+MK differentiated WTs from BCAs (AUC = 0.856).

CONCLUSION: DKI and DCE-MRI parameters complement each other, enabling accurate SGT subtype differentiation. Combined use of these parameters achieves high diagnostic accuracy, and a stepwise diagnostic flowchart was designed to facilitate systematic discrimination among the four tumor types.

ABSTRACT

PURPOSE: To look at the outcomes of various interventions in treatment-naive pediatric rhegmatogenous retinal detachment (RRD).

METHODS: This study was conducted at a tertiary care hospital in North India. Children below 16 years with treatment-naive RRD with a minimum 6-month follow-up were enrolled retrospectively from July 2012 to June 2021 and prospectively from July 2021 to June 2022. Patient demographics at presentation, risk factors, preoperative ophthalmic findings including best-corrected visual acuity (BCVA), the choice of surgery and tamponade, and postoperative assessment parameters were recorded. The primary outcome measure was anatomical success after surgery. Secondary outcome measures included functional success, that is, postoperative BCVA at last follow-up, improvement in vision, number of surgeries required to achieve final anatomical success, and correlation of factors such as age and etiology with outcomes. Functional success was taken as postoperative BCVA ≥ logMAR 1.3.

RESULTS: Among the 333 pediatric patients (348 eyes), the most common etiology was trauma (44.8%), followed by high myopia (17%) and idiopathic causes (15.5%). Primary anatomical success was achieved in 66.9% of cases, improving to 88.5% with additional surgeries. Functional success was recorded in 46.3% of cases. Combined scleral buckling (SB) and pars plana vitrectomy (PPV) provided the best anatomical (66.01%) and functional (48.32%) outcomes.

CONCLUSION: Pediatric RRD presents significant management challenges. Combined SB + PPV yielded superior outcomes. Functional recovery remains limited, emphasizing the need for early detection, improved surgical strategies, and long-term follow-up for optimal visual rehabilitation.

ABSTRACT

PURPOSE: To assess optical coherence tomography angiography (OCTA) changes in acute nonarteritic anterior ischemic optic neuropathy (NAION) eyes compared to fellow unaffected eyes and describe the longitudinal OCTA changes within the first 12 weeks of onset while the disc is still edematous.

DESIGN: A prospective observational study.

METHODS: A total of 30 patients, diagnosed with unilateral acute NAION, were included. Bilateral OCT and OCTA of the macula and optic nerve head (ONH) were done. Scans were performed at presentation and then at 6 weeks and 12 weeks thereafter.

RESULTS: Nerve fibre layer thickness (NFLT) and ganglion cell complex thickness (GCC) were significantly lower in diseased eyes after resolution of edema. Similarly, ONH and peripapillary vessel densities were significantly reduced in NAION eyes throughout the three visits, while macular superficial vessel density demonstrated a statistically significant decrease only from the second visit onward. Conversely, deep macular and foveal avascular zone (FAZ) vessel density (VD) showed no significant change in NAION eyes except at the third visit with lower VD in NAION eyes. However, all VD biomarkers of NAION eyes, including deep macular and FAZ VD, demonstrated a significant decrease in the 6-week and 12-week visits compared to baseline.

CONCLUSIONS: OCTA VD changes in NAION demonstrated a temporal sequence where radial peripapillary capillary vascular density was the first to decrease, followed by macular superficial vascular density and last the macular deep vascular density. Moreover, there was a progressive decrease in all OCTA VD measurements in NAION eyes during follow-up.

ABSTRACT

PURPOSE: To compare the clinical and imaging characteristics of isolated retinal astrocytic hamartoma (RAH) versus tuberous sclerosis complex (TSC)-associated RAH.

METHODS: This retrospective multicenter study included 38 patients diagnosed with RAH between 2000 and 2023. Clinical data and imaging findings were evaluated, including color fundus photography, optical coherence tomography (OCT), B-scan ultrasonography, and fundus autofluorescence. Statistical comparisons were performed between isolated and TSC-associated RAH.

RESULTS: The mean patient age was 26 years, with a slight male predominance (55%). Bilateral involvement was more common in TSC-associated RAH (55%). Overall, optical coherence tomography (OCT) of 18 eyes revealed optically empty cavities (44%), inner retinal disorganization (13%), outer retinal disorganization (8%), complete retinal disorganization (8%), and associated subretinal (SRF) and intraretinal fluid in 28% and 17% of eyes, respectively. Autofluorescence showed hyperautofluorescence in 86% and hypoautofluorescence in 14%, corresponding to calcified and noncalcified regions. Compared with isolated RAH, TSC-associated RAH demonstrated a higher prevalence of multifocal lesions (47% vs. 29%), superior quadrant involvement (86% vs. 40%), complete retinal disorganization (71% vs. 20%), and presence of SRF (100% vs. 0%).

CONCLUSION: TSC-associated RAH exhibits distinct morphological and imaging features, including greater multifocality and superior quadrant involvement. TSC-associated RAH exhibits more extensive retinal disorganization, frequent loss of deeper retinal layer visibility, and association with SRF, which may serve as an important diagnostic marker for systemic screening. Recognizing these differences aids ophthalmologists when evaluating RAH and associated TSC.

ABSTRACT

PURPOSE: To evaluate real-world outcomes of faricimab in treating diabetic macular edema (DMO) in treatment-naive and treatment-switch patients.

DESIGN: Retrospective audit.

METHODS: All patients with DMO initiating 6 mg faricimab at a London hospital between 01/01/2022-02/02/2024 were included. The protocol comprised four four-weekly loading doses followed by a treat-and-extend regimen tailored to response. Data collected included demographics, best-corrected visual acuity (BCVA), and central macular thickness (CMT).

RESULTS: Overall, 65 patients (87 eyes) received faricimab; 34 eyes (39.1%) were treatment-naive, and 53 eyes (60.9%) had switched from other treatments. In the treatment-naive group (24 patients; mean follow-up 8 months, SD = 3.8; 3-8 injections), mean age was 66 years (SD = 10), baseline VA: 59.5 EDTRS (SD = 13), and CMT: 485.1 μm (SD = 80), reducing to 327.2 μm (SD = 70; P < 0.0001). Final VA was 62.7 EDTRS (SD = 14; P = 0.259). The treatment-switched group (41 patients, 53 eyes) had a mean age of 65 (SD = 11) years. A total of 32 eyes (60.4%) had a single prior treatment; 25 had received aflibercept, four eyes had received ranibizumab, and three eyes had received dexamethasone implants. The other 21 (39.6%) eyes had combinations of these medications. Patients received 2-11 faricimab injections. Mean follow-up was 8.4 months (SD = 3.9), initial VA: 59.7 EDTRS (SD = 12.9), and CMT: 439.5 μm (SD = 102), decreasing to 366.9 μm (SD = 80.7) (P < 0.0001); final VA was 61.4 (SD = 15.4) (P = 0.55).

CONCLUSION: Faricimab significantly reduced CMT in both groups, with a greater reduction in treatment-naive eyes. VA improvement was, however, not statistically significant. Further studies are warranted to explore factors influencing visual outcomes.

ABSTRACT

PURPOSE: To present results from the Vitreo Retina Society-India (VRSI) 2024 Preference and Trends Survey, focusing on polypoidal choroidal vasculopathy (PCV) and diabetic retinopathy (DR) management practices among Indian vitreoretinal surgeons.

METHODS: Responses to a 62-item questionnaire, distributed to all VRSI members over email via Google Forms, were collected over 6 weeks in July–August 2024. Data were analyzed using descriptive statistics.

RESULTS: A total of 289 members participated in the survey. The majority of respondents preferred multimodal imaging for the diagnosis of PCV (44.68%) and aflibercept for initiation of therapy (63.12%). Respondents preferred a loading dose with a pro-re-nata regimen (46.45%) and a switch after three injections in cases of suboptimal response (57.45%), with a strong preference for switching to brolucizumab (63.93%). Pan-retinal photocoagulation was the predominantly preferred treatment modality for all cases of proliferative DR, with an increased preference for combining it with antivascular endothelial growth factor (anti-VEGF) in cases with high-risk characteristics. For centre-involving diabetic macular edema, ranibizumab biosimilars (40.79%) in a by pro re nata regimen (53.21%) were preferred. Respondents would switch to steroids (54.48%) for suboptimal response after three anti-VEGF injections (91.04%).

CONCLUSIONS: The current preferences in the management of PCV and DR among Indian vitreoretinal surgeons are reported here. The results of this survey will assist fellow practitioners in understanding contemporary real-world practices in relation to established literature and in developing appropriate guidelines.

ABSTRACT

This study is a quantitative, ecological, descriptive, retrospective, cross-sectional study on dengue in the state of Paraíba in north-eastern Brazil aimed to compare the performance of spatial clustering methods based on epidemiological data. The population consisted of all people residing in the state, and the sample was all dengue fever cases reported annually between 2018 and 2022. The residence localization of people suffering from dengue fever was used to identify the spatial distribution of this infection in the Paraíba State. Scan Statistics, Besag-Newell, Getis-Ord, MStatistics and Tango were used and it was observed that the methods Getis-Ord, M-Statistic and Tango showed large spatial clusters, which included municipalities with high and low values. Scan Statistics and Besag-Newell’s method also showed most of these clusters, with Scan Statistic providing better agreement with the high Standardized Incidence Ratio (SIR) than Besag-Newell’s method. In conclusion, Scan statistic outperformed the other methods by identifying significant clusters in greater proportion in all study periods when mapping using Rigorous Impact Evaluation (RIE) was applied. However, it is necessary to consider each method’s assumptions to select the most appropriate method for each application. Thus, this study provides relevant elements to help decision makers manage and prevent diseases, such as dengue fever and other vector-borne diseases.

ABSTRACT

Purpose: Dietitians (RDs) are well-positioned to drive food system transformation by supporting dietary patterns sourced from sustainable food systems (SFS). This research aims to identify how RDs conceptualize sustainability, describe SFS activities, define success, and determine the knowledge and skills required to practice in this area. Methods: A convenience sample of Canadian RDs completed a cross-sectional survey with open- and close-ended questions. Quantitative data were analyzed using descriptive statistics. Qualitative responses were thematically analyzed. Practice activities were mapped using the Socioecological Framework (SEF). Results: A diverse sample (n = 92) reported using common SFS definitions, frameworks, or other documents. Practice activities were reported on all levels of the SEF. Dietitians reported successes; however, the vagueness or responses suggested it may be too early to quantify these. Dietitians reported needing foundational and practice area-specific knowledge and skills and practical examples to support SFS in practice. Conclusions: Canadian RDs in this study demonstrated significant work in SFS using skills they developed to practice in other areas of dietetics. There is an opportunity to expand impact by sharing existing resources, developing new supports that include Indigenous perspectives and systems thinking, evolving RD roles, increasing macro-level strategies, and identifying success indicators to monitor impact.

ABSTRACT

Background and objective: The revisions of the DSM-5 and ICD-11 introduced several changes that altered the conceptualization of posttraumatic stress disorder (PTSD), potentially affecting diagnosis of children and adolescents. This study investigates the differences in rates of PTSD, diagnostic agreement, and comorbidity in children and adolescents when using DSM-5 or ICD-11.Method: The study is based on secondary analysis of data. Sample 1 and 2 consist of children and adolescents referred to mental health clinics (CAMHS) across Norway and sample 3 includes children referred to community services for trauma treatment. The total sample consisted of 290 children and adolescents (ages 7-18). Cohen’s kappa, McNemar tests and bootstrapped estimates with 95% CI were used to investigate our research questions.Results: The rate of _DSM-5PTSD (55.9%) was significantly higher than _ICD-11PTSD (33.2%), which seems to be particularly related to the re-experiencing criterion. There was a weak agreement of 74.5% between the two diagnoses manuals (kappa = .51). Using DSM-5 showed larger overlap between depression and PTSD (24.5% vs. 12.3%), as well as attention difficulties and PTSD (21.8% vs. 12.1%) as compared to ICD-11. However, our results also suggest that comorbidity rates for those with PTSD may be higher when using ICD-11 criteria compared to DSM-5 criteria (61.9% vs 53.1.% for depression).Conclusions: The results indicate that choice of diagnostic manual can influence whether children meet diagnostic criteria. Using ICD-11 criteria may help identify a subgroup of children and adolescents with more severe PTSD symptom profiles. Whereas using ICD-11 criteria is associated with high specificity of the diagnosis, it seems to also increase the comorbidity among those diagnosed. In contrast, utilizing DSM-5 criteria may identify children and adolescents with less distinct symptom presentations. Choice of diagnostic manual may influence access to evidence-based treatment.
