Decentralization Matters: Association of Adherence to Treatment and Distance for the Management of Non-Communicable Diseases in Rural Tanzania

Since March 2019, a non-communicable diseases program has been established at hospital level, with enrollment and clinical reassessment every 6 months. Since July 2023, monthly enrollment and visits have also been conducted at health center level. This study aimed at assessing the adherence to scheduled follow-up visits following the decentralization of the integrated NCDs program from Hospital to Health Center level and investigate factors influencing follow-up adherence. The study was performed in a rural district in Iringa Region, Tanzania. Adherence was measured at both levels. Multivariate regression analysis was conducted to describe socio-demographic and clinical factors influencing attendance at the 6-month hospital-level visit. Among 2198 patients enrolled at the hospital level, weighted adherence over 42 months was 40.8% (95% CI 39.0–42.6%) at the 6-month visit. Multivariate analysis revealed that as the distance from the hospital increased, the probability of attendance decreased (OR 0.17; 95% CI: 0.08–0.39). Among 571 patients enrolled at the residence level, adherence over the first 10 months of program implementation was 91.6% (90.4–92.8%). The findings showed that distance was by far the most important barrier to follow-up adherence and suggested that decentralizing the program from the hospital to peripheral health centers may ensure high follow-up rates.

Menstrual cups to reduce bacterial vaginosis and STIs through reduced harmful sexual and menstrual practices among economically vulnerable women: protocol of a single arm trial in western Kenya

BackgroundIn western Kenya, menstrual hygiene management (MHM) is a pervasive problem. Challenges are compounded for economically constrained women who continue to engage in sex during menses and resort to practices such as vaginal insertion of tissue and cotton to maintain dryness during sex. These practices can be harmful to the vaginal microbiome (VMB) and can lead to high rates of sexually transmitted infections (STIs) and HIV. This study will evaluate whether menstrual cups that can be worn during intercourse may be beneficial to the VMB and help prevent Bacterial vaginosis (BV) and STI acquisition among these economically vulnerable women.MethodsIn this single-arm trial among economically vulnerable women in semi-urban western Kenya, we will evaluate the preliminary efficacy of menstrual cups on non-optimal VMB, BV, and STIs, and investigate safety, acceptability, and implementation needs. Through peer referral we aim to recruit 402 menstruating women aged 15–35 who exchange sex for money or basic needs. Women who are pregnant, have delivered in the past six months, or use an intrauterine device (IUD) will not be eligible. Participants will be seen every six months for 24 months and be asked about their sexual and MHM practices, with samples collected to assess BV and VMB. At baseline, 12-, and 24-month visits, additional samples will be collected to measure HIV and STIs (C. trachomatis, N. gonorrhoeae, and T. vaginalis). HSV-2 status will be assessed at baseline. Intervention provision will consist of one reusable disc-shaped menstrual cup per participant and a group-based training within four weeks of the 12-month visit, followed by monthly telephone surveys for the first three months to assess cup use, adverse events, and provide any assistance. Primary analyses of preliminary efficacy will compare probabilities of optimal VMB, BV, and STIs in the pre-intervention period to the post-intervention period. Primary safety analyses will compare occurrence of menstrual toxic shock syndrome and cervicovaginal laceration.DiscussionIf demonstrated safe and effective, this multipurpose reproductive health intervention will offer a dignified solution for the menstrual hygiene needs of women who engage in sex for livelihood and reduce their occurrence of non-optimal VMB, BV, and STIs.Trial registrationClinicaltrials.gov NCT05666778 (28th December, 2022); Pan African Clinical Trials Registry 202,305,912,778,108 (25th May, 2023).

Retreatment and aesthetic restoration of maxillary incisor with calcified root canal using a dynamic navigation system: a case report

BackgroundPulp canal occlusion (PCO) increases the difficulty of root canal treatment as well as tooth preservation and restoration. This is the first case report of successful localization of a calcified root canal under the guidance of a dynamic navigation system (DNS) for complete root canal retreatment and aesthetic restoration after a failed attempt to locate the calcified root canal with a traditional dental operating microscope (DOM).Case presentationThe patient was scheduled for root canal treatment for a labially inclined maxillary central incisor and post-core crown restoration with resin veneers in another hospital, but the calcified root canal could not be located with a microscope, so the patient was referred to our department. Root canal retreatment was planned for tooth #8, and the calcified root canal of tooth #9 was planned to be located and dredged under the guidance of a DNS. We used a DNS for successful positioning and to complete the root canal retreatment operation in the following 4 steps: preoperative CBCT imaging, preoperative plan design, calibration and registration, and real-time dynamic navigation. Three months later, teeth #8 and #9 presented no clinical symptoms, after which the fiber post-cores and zirconia all-ceramic crown restorations were completed. At the 12-month follow-up visit, the patient continued to be symptom­free, and satisfied with the final aesthetic restoration.ConclusionsThis case report suggests that DNS may be a promising technique with high accuracy and effectiveness to reduce the risk of iatrogenic errors and provide maximal preservation of dentin, when the traditional treatment of calcified root canals approaches failure (lateral perforation).

Hands Up Program: Results of a feasibility study of a randomized controlled trial of a bone health exercise and education program for adults aged 50-65 post distal radius fracture.

Distal radius fractures (DRF) that occur from a fall from level ground are considered fragility fractures and may be the first indication that someone has compromised bone mineral density and is at risk of having osteoporosis. Women at about 50 years of age experience a dramatic increase risk of these fractures. Rehabilitation after DRF focuses on restoring range of motion and strength in the wrist, but rarely address future bone health concerns. We developed a 6-week therapist-developed remote full body exercise and osteoporosis/bone-health education program (called The Hands Up Program). This study was designed to evaluate the feasibility of a larger trial examining the effects of a whole-body exercise and education program for people 50-65 after a DRF. Community dwelling individuals between the age of 50-65 with a radiographically confirmed DRF were recruited from the Roth| McFarlane Hand and Upper Limb Center in London, Ontario. Participants were randomized in a 1:1 ratio into either the Hands Up Program which was a twice weekly exercise and education program for 6 weeks, or the control group where they proceeded with usual care. The intervention was delivered online through a website where participants created a unique username and password to access. The primary feasibility outcomes of the study were recruitment rate (74 participants in 1 year), retention rate (75% completion), and intervention adherence rate (60% of completion of the exercise program). Secondary outcomes included strength, range of motion, self-reported outcomes, and bone density. Overall, 74 participants were recruited in 14 months. Retention did not meet the criteria for success, as only 53% of the participants attended their 12-month visit. Adherence was also not met albeit close with 55% completing the exercise program. Twelve participants withdrew from the study, five due to the time commitment, four without explanation, one due to group allocation, one due to COVID and one participant moved. One participant was deemed ineligible after consent. Four of the participants that withdrew were in the intervention group, and four in the control group, five participants withdrew before they were allocated to a group. Feedback from patients indicated potential improvements to the program: lower assessment burden, spacing out the intervention so that the education portion could be delivered during the immobilization phase of recovery, and creating a more individualized program. Adherence and retention were both a challenge, although adherence was close to target. While achieving adherence to exercise in bone health is a known challenge, given the importance of prevention in the at-risk DRF population and the challenges in co-design and delivery during the pandemic, we believe evaluation of a revitalized program is warranted.

Posterior Cruciate Ligament Reconstruction Improves Sexual Health Post-Operatively

PurposeThe purpose of this study was to investigate changes in sexual function and quality of life following arthroscopic posterior cruciate ligament (PCL) reconstruction. MethodsPatients aged between 18 and 45 years who underwent PCL reconstruction were considered for inclusion. At the time of hospital admission, each patient was asked to complete the New Sexual Satisfaction Scale-Short Form (NSSS-S), before injury (preinjury) and at the time of hospital admission (preoperative). In addition, patients were followed for a minimum of 24 months (final follow-up). Quality of life was measured using the Anterior Cruciate Ligament Quality of Life Questionnaire (ACL-QOL) at hospital admission (preoperative) and at the 24-month follow-up visit (final follow-up). ResultsA total of 35 patients were included in the study; 24 (68.6%) were male, and 11 were female (31.4%). The mean age at the time of surgery was 29.23 ±7.52 years, and the mean follow-up duration was 52.97 ±22.69 months. In all patients, the hamstring tendon was used. Sexual activity at the last follow-up visit was significantly different from that preoperatively (p=0.024), while no difference was observed between the preinjury and last follow-up values (p=0.243). Sexual activity was more frequent before injury than preoperatively (p=0.009). Quality of life at the last follow-up visit was significantly better than that preoperatively (p<0.001). ConclusionsReconstructive surgery after PCL injury improves the sexual health of patients regardless of age or sex.

Visual recovery following pituitary adenoma surgery: prognostic value of optical coherence tomography and suprasellar tumour volume

ObjectiveThe aim of this study is to investigate the effects of preoperative parameters such as retinal nerve fiber layer (RNFL) thickness, visual acuity (VA), visual field (VF), and tumour volume on postoperative outcomes in patients with pituitary adenoma. DesignRetrospective study. ParticipantsTwo-hundred and seventy-six eyes from 142 patients were included. MethodsAll patients underwent a comprehensive ophthalmological evaluation both before and 12 months after the surgery. RNFL thickness was analyzed using optical coherence tomography. VF testing was carried out using the automated Humphrey Visual Field Analyzer 3. Two primary visual field (VF) parameters, mean deviation (MD), and pattern standard deviation (PSD), were recorded. Patients were categorized into 2 groups based on their visual field outcomes: the MD recovery group and the nonrecovery group. MD recovery was defined as an MD value greater than −2 dB at the 12-month postoperative follow-up visit. ResultsThe mean BCVA was significantly improved postoperatively compared with the preoperative values (P = 0.001). Preoperatively, the upper, temporal, and inferior RNFL values were significantly higher in patients with normal visual fields compared to those with abnormal visual fields (P = 0.001 for upper and temporal, P = 0.008 for inferior). Preoperative suprasellar tumour volume was found to be lower in the MD recovery group (P = 0.001). Multivariate logistic regression analyses revealed that preoperative inferior RNFL thickness were significantly associated with MD recovery (P = 0.023), and preoperative temporal RNFL thickness were significantly associated with VA recovery (P = 0.047). ConclusionRNFL thickness, VF parameters, and suprasellar tumour volume can serve as important prognostic indicators in patients with pituitary adenoma.

Synthetic medial meniscus implant demonstrates high reoperation rates: Patients who retain implant or require implant exchange show improvement in post meniscectomy knee pain and clinical function

PurposeThe purpose of this study was to evaluate the clinical outcomes in the use of a synthetic medial meniscus implant in patients symptomatic after medial meniscectomy and not responsive to other treatment methods. and not responded to non-operative treatment. MethodsThis single-arm, multicenter, prospective study enrolled subjects between ages 30-75 with post-meniscectomy pain. Changes from baseline to 24-months were measured in the pain subscale of the knee injury and osteoarthritis outcome score (KOOS) and in KOOS overall (average of all five subscales) in patients that had received a medial meniscus implant. Success was a 20-point improvement at 24-months, reoperation rates, and implant failures were recorded. VAS, IKDC, and WOMET scores were also measured. ResultsOf the 115 treated patients 3 (2.6%) were either lost to follow-up or missed the 24-month visit, 48 (43%) patients had at least one subsequent surgery, 12 (10.7%) had the implant permanently removed. Of the remaining 100 patients, the mean KOOS pain improved 28.4 points at 24 months (P <0.001), and mean KOOS overall improved 28.3 points (P < 0.001). Seventy-six percent of subjects had mean scores for KOOS pain above the minimal clinically important difference (MCID) threshold, and 72% of subjects met or exceeded this threshold for KOOS overall. There were 29 patients (25.9%) who underwent implant exchange. The 24-month clinical outcomes were similar between subjects who had an implant exchange and patients who did not have any subsequent implant procedure (P < 0.2). ConclusionThe synthetic medial meniscus demonstrates high reoperation and failure rates. Patients who retained the implant or required implant exchange showed significantly improved pain, function, and quality of life at 24-month follow-up in patients symptomatic following partial medial meniscectomy and failed non-operative management. The high reoperation rate is a concern, and further evaluation is needed to determine any contributing factors.

Prolonged dual antiplatelet therapy in an extended Phase 3 Cardiac Rehabilitation Program following myocardial infarction

Abstract Background Prolonged dual antiplatelet therapy (P-DAPT) is recommended in selected patients beyond 12 months after myocardial infarction (MI). Several risk scores have been developed to estimate the ischemic and bleeding risk and individualize the decision-making process. Purpose We aim to analyse the factors, including ischemic and bleeding scores, associated with P-DAPT prescription in MI patients submitted to a Cardiac Rehabilitation Program (CRP). Methods Patients with ST-segment elevation MI (STEMI) or occlusion MI (OMI) who were submitted to our CRP underwent Phase 2 CRP and were prospectively included. Patients were followed in an extended Phase 3 CRP, and a follow-up visit was scheduled 12 months after hospital discharge. Baseline and follow-up clinical characteristics and treatment after the 12-months visit were registered, specifically P-DAPT. Ischemic (DAPT score) and bleeding (PRECISE-DAPT and CRUSADE scores) risk scores were retrospectively computed. Predictors of P-DAPT were studied by univariate analysis and multivariable binary logistic regression. The model was tested by area under the curve (AUC) analysis in receiver operating characteristic curves. A p&amp;lt;0.05 was considered statistically significant. Results The cohort comprised 78 patients (mean age 61±11 years, 84.6% male). Anterior and inferior STEMI were the most common presentations (43.6% and 47.4%, respectively). The most prevalent cardiovascular risks factors were hypercholesterolemia (85.9%), hypertension (53.8%), smoking habit (46.2%) and diabetes mellitus (23.1%). P-DAPT was prescribed in 39 (50%) patients beyond 12 months after MI, primarily combining aspirin 100mg o.d. and ticagrelor 60mg b.i.d. (n=33, 84.6%). On multivariate analysis, variables associated with P-DAPT prescription were hypertension (HR 4.92 [1.37-17.68], p=0.02), diabetes mellitus (HR 5.13 [1.09-24.09], p=0.04), multivessel disease (HR 5.54 [1.55-19.79], p=0.008), and stent diameter &amp;lt;3mm (HR 5.46 [1.25-23.78], p=0.02). The predictive power of the model was excellent (AUC 0.88 [0.8-0.96], p&amp;lt;0.001). Ischemic (DAPT score) and bleeding (PRECISE-DAPT and CRUSADE) risk scores were not associated with P-DAPT neither in continuous form nor by using their standard cutoffs (≥2, &amp;lt;25 and &amp;gt;40 points, respectively). Conclusions In a real-life cohort of MI patients undergoing extended Phase 3 Cardiac Rehabilitation, P-DAPT was prescribed in half of the population. Clinical (hypertension and diabetes mellitus) and angiographic (multivessel disease and stent diameter &amp;lt;3mm) variables straightforwardly predict the likelihood of receiving P-DAPT, unlike ischemic and bleeding risk scores. The clinical consequences of this management should be further explored.Prolonged DAPT in Cardiac Rehabilitation

Masked hypotension in patients with heart failure

Abstract Background Hypotension limits the up-titration of guideline-directed medical therapies (GDMTs) and correlates with poor prognosis in patients with heart failure. The value of ambulatory blood pressure monitoring (ABPM) in heart failure patients and its association with GDMTs optimization and clinical outcomes were undetermined. Methods REM-HF (Risk Evaluation and Management in Heart Failure) is a multicenter, prospective observational cohort. Our study screened patients from REM-HF who were hospitalized for incident HF and newly initiated GDMTs between April 2018 and December 2022. Eligible participants conducted a 24-hour ABPM before discharge and were followed-up as the cohort routine. GDMTs target dose achievement and dose trajectories were assessed at 3-month visit. The primary outcome was a composite of all-cause mortality and heart failure readmission. Results On adjusted restricted cubic spline analysis, office SBP demonstrated a U-shape relationship with the primary outcome (P for nonlinearity=0.003), while 24-hour SBP was linear (P for nonlinearity=0.338). The risk-related threshold of ambulatory and office systolic hypotension was defined as corresponding SBP &amp;lt; 120 mmHg accordingly. Combining these two measurements together, we described three blood pressure status as sustained hypotension (s-hypo, both SBP &amp;lt; 120 mmHg), masked hypotension (m-hypo, 24h SBP &amp;lt; 120 mmHg while office SBP ≥ 120mmHg), and non-hypotension (n-hypo). Among the 491 patients included, 124 (25.3%), 151 (30.8%) and 216 (44.0%) had s-hypo, m-hypo, and n-hypo, respectively. The m-hypo group showed similar clinical features as the s-hypo subjects, including more serious left ventricle remodeling and worse cardiac function. After the GDMTs dose titration, either patients with s-hypo or m-hypo were as unlikely to achieve target dose as the non-hypotensives (OR for s-hypo 0.42, 95%CI 0.19-0.95, P=0.038; OR for m-hypo 0.39, 95%CI 0.19-0.80, P=0.011). During a median follow-up of 693 days, the adjusted risk of primary outcome was higher in the s-hypo group and m-hypo group compared with the non-hypo group (HR for s-hypo 2.47, 95%CI 1.54-3.96, P&amp;lt;0.001; HR for m-hypo 1.68, 95%CI 1.06-2.65, P=0.027). No significant differences were found in target dose achievement and clinical outcomes between the s-hypo and m-hypo groups. Conclusion Masked systolic hypotension can occur in nearly one-third of new-onset HF patients. Patients with m-hypo and s-hypo exhibit similar clinical characteristics, both associated with GDMTs intolerance and adverse outcomes, suggesting m-hypo deserves recognition as a discrete entity. ABPM provides a more comprehensive view of patients’ blood pressure status by identifying this population.

Mechanical dyssynchrony and response to cardiac resynchronization therapy in heart failure patients with right ventricular pacing: a pre-specified subgroup analysis of the BUDAPEST CRT Upgrade trial

Abstract Introduction The BUDAPEST CRT Upgrade trial has established the strong clinical benefit of upgrading heart failure patients with a reduced left ventricular (LV) ejection fraction (HFrEF) and a high right ventricular pacing (RVP) burden to cardiac resynchronization therapy with defibrillator (CRT-D). Importantly, however, the CRT upgrade response is not homogeneous regarding LV reverse remodeling and associated clinical outcomes. The presence of mechanical dyssynchrony (MD) assessed by echocardiography has been linked to more CRT benefits; still, its change in response to CRT and added prognostic value in HFrEF patients with high RVP are scarcely investigated. Purpose Accordingly, we aimed to assess the prevalence, clinical characteristics, CRT response rate, and prognostic value of RVP-induced MD in the BUDAPEST CRT Upgrade cohort. Methods The multicentre, randomized, controlled trial enrolled 360 HFrEF patients with a pacemaker or implantable cardioverter defibrillator (ICD) and significant RVP (≥ 20%) who were randomly assigned to receive CRT-D upgrade or ICD in a 3:2 ratio. Protocol echocardiography was performed at baseline and at 12-month follow-up visits and was evaluated at a central core lab. Beyond LV end-diastolic (EDV) and end-systolic volumes (ESV), longitudinal strain-derived septal deformation patterns by speckle tracking were assessed to determine the presence of RVP-induced MD. The endpoints were volumetric non-response (defined by a relative decrease in LV ESV &amp;lt;15%) and the composite of volumetric non-response or HF hospitalization. Results The echocardiographic assessment was feasible in 325 patients at baseline; 133 (41%) patients presented with MD. Females were more likely to present with MD (female vs. male, 65% vs. 38%, p=0.003). MD patients had higher LV EDV (MD vs. no-MD, 248±78 vs. 219±78 mL, p=0.001) and LV ESV (190±67 vs. 165±64 mL, p&amp;lt;0.001) at baseline. In the CRT-D group, 126 (75%) patients were volumetric responders, and 41 (25%) were non-responders at 12 months. CRT patients with baseline MD were less likely to experience volumetric non-response (OR 0.35 [95% CI 0.15-0.82], p=0.015) or the composite endpoint (OR 0.37 [95% CI 0.17-0.77], p=0.008). Out of 57 CRT patients with baseline MD who had follow-up assessment available, 52 (91%) patients had a favorable change: the MD pattern disappeared. Patients with MD resolution at 12 months were less likely to experience volumetric non-response or the composite endpoint (OR 0.39 [95% CI 0.17-0.93], p=0.034; OR 0.38 [95% CI 0.16-0.86], p=0.021, respectively). CRT patients with resolved MD were less likely of ischemic etiology and had 100% posterior or lateral LV lead location. Conclusions The presence of RVP-induced MD and its resolution is associated with better clinical response in HFrEF patients undergoing CRT-D upgrade. MD assessment can refine patient selection algorithms of CRT.Figure 1

Clinical Evaluation of Violet Light Filtration and High-Resolution Lathing on a Diffractive Extended Depth of Focus IOL.

This study is a prospective, randomized, subject/evaluator-masked clinical trial in a single-center clinical setting. The purpose of the study is to compare the clinical performance of Tecnis Symfony Optiblue IOL (models ZXR00V and ZXW150) with violet light filter (VLF) and manufacturing improvements versus Tecnis Symfony IOL (models ZXR00 and ZXT150) with ultraviolet light filter (UVF) in patients undergoing cataract surgery. Patients with cataracts aged ≥ 22years were randomly assigned 1:1 to bilateral implantation with ZXR00V/ZXW150 (VLF group) or ZXR00/ZXT150 (UVF group). Key endpoints at 6months postoperative included patient reported nighttime dysphotopsia symptoms, 25% low contrast visual acuity with glare, and patient satisfaction. Sixty patients were implanted with ZXR00V/ZXW150 (30) or ZXR00/ZXT150 (30). At 6months, the VLF group did not show a statistically significant differences in mean monocular photopic uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), uncorrected near visual acuity (UCNVA) (40cm), or distance-corrected near visual acuity (DCNVA) (40cm) compared to the UVF group. At 1month, patients in the VLF group reported significantly less difficulty due to halo (p = 0.016) and starburst (p = 0.028) symptoms. By the 6months, dysphotopsia complaints were no longer significantly different between the groups. Although the VLF group trended toward better low contrast visual acuity and patient satisfaction, statistical significance was not reached. Managing the patients' expectations is key to achieving success. At the 1-month visit the patients who reported dysphotopsia complaints in the VLF group had significantly less difficulty with starbursts and halos as compared to the UVF group. By the 6-month visit, there was no significant difference between the two groups in the difficulty with starbursts and halos. ClinicalTrials.gov identifier, NCT06567834.

15 Predictive validity of two developmental screening tools at the 18-month visit and neurodevelopmental consultation at an average age of 8 years

Abstract Background The Canadian Paediatric Society (CPS) recommends an enhanced 18-month well-baby visit incorporating a developmental screening tool to stimulate discussion with parents, and notes that a widely used tool is the Nipissing District Developmental Screen (NDDS). For early detection of autism spectrum disorder, the CPS notes that a commonly used screening tool is the Infant Toddler Checklist (ITC). Objectives To examine the predictive validity of the ITC and NDDS at the 18-month visit using later neurodevelopmental consultation as the criterion measure; and examine whether positive developmental screening was associated with health care utilization (HCU). Design/Methods Using a prospective design, parents completed the ITC and the NDDS at the 18-month visit in primary care practices. Seven types of HCU were collected from health administrative databases, via linkage using the child’s health insurance number, including: neurodevelopmental consultation, special paediatric consultation, scheduled primary care visit billings, unscheduled primary care or minor visit billings, other non-primary care visit billings, hospitalizations, and emergency department visits. Covariates included child and family characteristics. We calculated screening test properties (using neurodevelopmental consultation as the criterion) and used multivariable negative binomial regression to estimate rate ratios (RR) for each of the 7 types of HCU. Results For both the ITC (n=1460) and NDDS (n=802) cohorts, mean age at screening was 18 months and mean age at follow up was 8 years. Of the ITC cohort, 11% were screen positive, 2.6% had a neurodevelopmental consultation. A positive ITC had 40% sensitivity (95% CI 24%-57%), 90% specificity (95% CI 88%-91%), 10% false positive rate (95% CI 9%-12%). A positive ITC was associated with 6 of 7 types of HCU, including neurodevelopmental consultation (RR=2.78, 95% CI 1.37-5.67). Of the NDDS cohort, 36% were screen positive, 2.5% had a neurodevelopmental consultation. A positive NDDS had a sensitivity of 50% (95% CI 27%-73%), specificity of 65% (95% CI 61%-68%), false positive rate of 35% (95% CI 31%-40%). A positive NDDS was associated with only 1 of 7 types of HCU: unscheduled primary care or minor visit billings 1.24 (95% CI 1.01, 1.53, p=0.04). Conclusion The predictive validity of the ITC was stronger than the NDDS due to high specificity and low false positive rates. The low sensitivity of the ITC is similar to other screening tools used at 18 months, highlighting the importance of ongoing developmental surveillance. The false positive rate of the NDDS is unacceptably high for a screening tool.

Challenging Case: Family Navigation for Autism Spectrum Disorder.

Leo is a 28-month-old boy from a monolingual Spanish-speaking family who was referred to a developmental-behavioral pediatrics (DBP) clinic for concerns regarding autism. His parents migrated to the United States 8 years ago and currently live and work on a farm. He was born in a US hospital after an uncomplicated pregnancy and has been generally healthy. His parents first became concerned about his development when he was 16 months old. He stopped saying mama/dada in Spanish and started lining up random objects. He had frequent temper tantrums and was difficult to console during unexpected changes in his routine. He screened positive on the Modified Checklist for Autism in Toddlers,Revised with Follow-Up (M-CHAT-R/F) at his 18-month well-child visit, and his pediatrician referred him to the local early intervention program. Calls from the early intervention program to his parents were unanswered. At his 24-month well-child visit, he again screened positive on the M-CHAT-R/F, and his pediatrician placed a referral for a DBP consultation. During the DBP visit at 28 months of age, developmental testing indicated his receptive and expressive language skills to be in the extremely low range, with significant scatter in his cognitive and adaptive skills. Behavioral observations were consistent with parental history and showed differences in social communication and interaction, the presence of repetitive behaviors, and extreme distress with transitions. He was diagnosed with autism spectrum disorder. Recommendations, including referral to early intervention, applied behavior analysis therapy, speech and language therapy, audiology evaluation, and genetic testing, were discussed with his parents through an interpreter. An autism packet, written in Spanish, with detailed information about autism and community resources was given to the family. By the time of a follow-up DBP visit 6 months later, Leo had not started on any early intervention or therapeutic services. Where do you go from here?

Sensor-Acquired Reachable Workspace (RWS) Correlates with Activities of Daily Living (ADL) Function in Stroke as Measured by Functional Independence Measure (FIM) Self-Care

Optimal upper extremity motor control and range of motion are necessary to achieve even the basic activities of daily living (ADL) function. Stroke, with resulting hemiparesis, can significantly and negatively impact an individual’s ADL function. Functional Independence Measure (FIM) self-care score can provide an assessment of what aspects and to what degree ADL functions are impaired. FIM self-care assessment can also track changes in ADL function during stroke recovery and rehabilitation. Recently, the sensor-acquired 3D motion analysis of stroke patients’ upper extremity has shown promise as a potential alternative to assess ADL function. This observational study evaluates whether the sensor-acquired upper extremity reachable workspace (RWS) measure correlates with clinician-evaluated FIM self-care score in stroke patients. Seventeen patients with stroke were enrolled in the study. FIM self-care, NeuroQoL upper extremity, and reachable workspace outcome measures (relative surface area, RSA) were collected upon rehabilitation hospital admission, at discharge, and at the 3-month visit. Pearson and Spearman’s rank correlation coefficients as well as multiple linear regression analyses were used to determine the relationships between FIM self-care, NeuroQoL, and reachable workspace RSAs. Moderately strong correlation between total reachable workspace RSA and total FIM self-care score at discharge and at 3 months were noted (r = 0.619, r = 0.661, p &lt; 0.05), and similarly strong correlation was also noted with the upper extremity NeuroQoL total score (r = 0.690, r = 0.815, p &lt; 0.05). Multiple linear regression analyses revealed a change in average bilateral total RSA of 0.1 unit from admission to the 3-month follow-up correlated with a respective change in the FIM self-care score of 2.011 points (95%CI: 0.663–3.360). Longitudinal improvement in ADL function during stroke rehabilitation and recovery process is correlated with improvement in reachable workspace.

Ahmed's sub-flap mattress suture deep sclerectomy assessment with Ultrasound Biomicroscopy.

To assess the efficacy of adding Ahmed's sub-flap mattress suture to deep sclerectomy (DS). Forty eyes with open angle glaucoma were assigned randomly into two groups: Group A: underwent DS with Ahmed's sub-flap mattress suture. Group B: underwent conventional DS. Patients were followed up closely for 6 months with serial IOP measurements and ultrasound biomicroscopy (UBM) was used to assess the surgical site functionally and anatomically at the first and sixth month. Adding Ahmed's sub-flap mattress suture improved the IOP lowering effect of DS significantly from 43% in group B to 53% in group A at 6-month (p = 0.027). IOP in group A was at 1 week, 1 month and 6-month visits (7.9 ± 1.3, 11.7 ± 2.2 and 13.3 ± 1.9 mmHg respectively) compared to group B (10.1 ± 4.6, 14.1 ± 5.2 and 16.8 ± 4.1 mmHg respectively) (p = 0.025, 0.041 and 0.001 respectively). UBM parameters were significantly larger in group A at 1 and 6 months. Strong statistically significant negative correlations were established between IOP and all the UBM parameters apart from intrascleral lake height at the first and sixth month (p < 0.01 in all of them). Finally, significant correlations were found between IOP at 6 months and whole bleb anteroposterior length and height at 1 month (p = 0.001). Adding Ahmed's sub-flap mattress suture to routine DS is an effective economical addition that will enhance the IOP lowering effect of DS. Also, assessment of the bleb by UBM is useful in predicting the success of deep sclerectomy surgery.

Deprescribing antipsychotics in patients with schizophrenia: findings from a specialized clinic.

While antipsychotic medication reduces the risk of relapse for patients with schizophrenia, high prevalence of adverse effects results in low adherence. Lower doses of antipsychotics have been associated with increased level of function but also with increased risk of relapse. This study presents findings from a specialized deprescribing clinic. In addition, we aim to identify clinical predictors for relapse. Patients diagnosed with schizophrenia were referred to the clinic, which offers a six-month guided tapering program. Antipsychotic dose was reduced by 10% every four weeks. Patients were monitored closely for symptom progression or decrease in level of function, with defined cut-offs prompting a pause in or cessation of dose reduction. After 12 months, the antipsychotic dose was reduced from 404 (±320 mg) to 255 (±236 mg) chlorpromazine equivalent. Of the 88 patients included, 22 (27%) experienced relapse during the six-month tapering period, while 29 (37%) experienced relapse at the 12-month follow-up visit and nine patients were antipsychotic free. Patients who remained stable experienced a slightly increased level of functioning and markedly fewer side effects (p < 0.001). Following relapse, patients were clinically stabilized and showed an improved attitude toward antipsychotic medication. The predictive models were weak. We show that most patients undergoing guided antipsychotic tapering remained stable after one year and improved in level of function, while most patients who relapsed were quickly stabilized. Our inability to create strong predictive models could be due to limitations in the study design, warranting future studies exploring tapering of antipsychotics in patients with schizophrenia.

One-year outcomes after intraocular collamer lens implantation in hyperopic astigmatism: a retrospective single-center study.

Astigmatism is the most prevalent refractive error among children and adults, and it can lead to visual impairment if left uncorrected. The management of compound hyperopic astigmatism is more challenging. This study presents the 12-month outcomes of toric implantable collamer lens (ICL) implantation in eyes with hyperopic astigmatism. This interventional case series included patients with simple or compound hyperopic astigmatism who underwent toric ICL implantation. All eligible individuals underwent a detailed ocular examination. Uncorrected and corrected distance visual acuities (UDVA and CDVA, respectively), intraocular pressure, and manifest and cycloplegic refraction results were documented. Pentacam corneal tomography was performed to assess the central corneal thickness, iridocorneal angle width, and anterior chamber depth. Endothelioscopy was performed to determine endothelial cell density. The ICL V4b model was implanted in all the included eyes. Safety and efficacy indices were calculated as postoperative CDVA/preoperative CDVA and postoperative UDVA/preoperative CDVA, respectively. Twenty-six eyes with low-grade simple or compound hyperopic astigmatism were included. All eyes experienced a significant improvement of four lines in postoperative UDVA (P < 0.001), and their postoperative CDVA remained stable at the 12-month follow-up (P > 0.05). The safety and efficacy indices were 1.0. None of the eyes lost two or more lines of CDVA; in 81% of the eyes, CDVA was unchanged, and the proportion of eyes with 20/30 or better postoperative UDVA was identical to that with 20/30 or better preoperative CDVA (81% for each). The mean manifest spherical equivalent at the 12-month postoperative visit had significantly improved (P < 0.001). The percentages of eyes with postoperative spherical equivalent within ± 0.50 D and ± 1.00 D were 81% and 96%, respectively. The postoperative refractive cylinder improved significantly (P < 0.05), and the percentage of eyes with refractive cylinder within ± 0.50 DC and ± 1.00 DC were 50% and 77%, respectively. Our outcomes indicate that toric ICL implantation is safe and effective for managing low-grade simple or compound hyperopic astigmatism. The proportion of eyes with 20/30 or better postoperative UDVA was identical to that with a 20/30 or better preoperative CDVA. The manifest spherical equivalent and refractive cylinder were significantly reduced. No serious safety concerns were observed. Further prospective large-scale studies with a wide range of ages and grades of hyperopic astigmatism are required to verify these preliminary outcomes.

Visual and patient reported outcomes provided by a refractive multifocal intraocular lens based on continuous transitional focus

PurposeTo analyze the quality of vision of patients implanted bilaterally with the multifocal Precizon Presbyopic intraocular lens (IOL), as well as to evaluate the visual performance provided by the lens.SettingVissum Miranza Alicante.DesignProspective multicenter study.Methods56 patients (mean age 65.0 ± 8.7 years old) underwent bilateral implantation with multifocal Precizon Presbyopic IOL. The quality of vision was assessed by a quality of vision questionnaire at 6 months after the implantation procedure, a complete eye examination was also performed including visual and refractive measurements, defocus curve and contrast sensitivity assessment. Visual and refractive variables were compared in preoperative, 3-month postoperative and 6-month postoperative visits by Wilcoxon test.ResultsThe quality of vision analysis showed the absence of severe glare and severe haloes in all evaluated patients. Likewise, non-symptoms of glare, haloes and starbursts were seen in 75%, 68%, and 55% of subjects, respectively. Efficacy and safety index was 1.26 and 1.42, respectively. The 6-month postoperative binocular uncorrected distance visual acuity and near uncorrected visual acuity were 0.00 ± 0.09 and 0.20 ± 0.13 logMAR, respectively. Mean spherical equivalent was 0.29 ± 0.45 D.ConclusionsThe Precizon Presbyopic NVA IOL (OPHTEC BV) provides a suitable quality of vision with a low rate of disturbance photic phenomena induction, as well as an excellent visual performance at main distances of sight accomplishing the visual demands of the majority of patients.

A Directed Content Analysis of Discussions Between Mothers and Pediatricians Around Feeding and Growth Topics During Infant Well-Child Visits.

This study identified specific feeding and growth topics discussed during 2-, 4-, and 6-month well-child visits. Conversations between mothers (N = 20) and pediatricians (N = 5) during visits were audio-recorded. Conversation segments were classified as pediatrician-initiated guidance, mother-initiated questions/concerns, or updates using directed content analysis. Pediatricians and mothers completed surveys on perceptions of guidance delivered. Feeding clusters included introducing solids/drinks, breast milk/formula amount and timing, feeding in specific situations; and breast milk/formula preparation. Growth clusters included appropriate growth and growth tracking. There was considerable variability in specific topics discussed between and within families across visits. Mothers desired additional guidance around introducing solids (42.1%) and allergen foods (31.6%). Pediatricians (80%) felt the amount of guidance to deliver in a standard visit was too much, and additional guidance outside of visits would benefit caregivers. Future research should investigate strategies to further support families by offering additional guidance during or outside of well-child visits.

Palatal root endodontic microsurgery in maxillary molars using the palatal approach: a case study

BackgroundIn clinical practice, the buccal approach is typically the primary choice for endodontic microsurgery. Owing to the thickness of the buccal bone plate, the distance between the buccal bone plate and palatal lesion location, and soft tissue traction, the palatal approach may be more suitable for microsurgery for apical periodontitis of the palatal roots of the maxillary molars. However, the length of the palatal root, location of the greater palatine artery (GPA) and foramen (GPF), and surgical field of observation make palatal surgery challenging.Case presentationWith the aid of Cone-beam computed tomography imaging, the palatal approach was successfully applied in nine cases of endodontic microsurgery of the palatal root of a maxillary molar with a periapical lesion in Hangzhou Stomatology Hospital from January to December 2022.ConclusionsComplete healing was assessed based on clinical symptoms and radiographic images at the 3- and 24-month follow-up visits in all nine cases. Several tips have been proposed including surgical positioning, incision design, palate flap modification, bone removal, and root-end resection.
