Purpose:
This study evaluated the long-term clinical outcomes of silicone tube intubation using a Nunchaku® (FCI Ophthalmics Inc., Pembroke, MA, USA) tube in adult patients with epiphora.
Methods:
A prospective study was conducted on 42 eyes in 32 patients who underwent silicone tube intubation with a Nunchaku® tube between March 2023 and September 2023. Clinical manifestations, Munk scale scores, lacrimal syringing test results, and tear meniscus height were assessed before and after surgery. Surgical success was defined as a Munk score of ≤ 1.
Results:
The mean age of the participants was 56.2 years. Preoperative lacrimal irrigation testing revealed partial obstruction in 29 eyes (69.0%), patent passage in 11 eyes (26.2%), and punctal stenosis in 2 eyes (4.76%). The mean operative time was 6.4 minutes for monocular procedures and 9.7 minutes for binocular procedures. At three months postoperatively, 33 eyes (78.6%) in 28 patients achieved a Munk scale score of ≤ 1. No significant differences were observed between the surgical success and failure groups in terms of preoperative Munk scale scores, lacrimal syringing test results, or tear meniscus height. One patient who underwent binocular surgery experienced worsening symptoms in both eyes postoperatively with associated punctal inflammation and granuloma formation necessitating early silicone tube removal. Slit punctum was observed in 17 eyes across 11 patients, six of whom underwent a snip procedure during surgery.
Conclusions
Silicone tube intubation using the Nunchaku-style tube is a relatively simple and effective treatment for nasolacrimal duct obstruction. However, an increased incidence of lacrimal punctum-related complications was observed compared to previous studies, indicating the need for caution when performing the snip procedure concurrently.

We evaluated the effectiveness of the predictive low-glucose suspend (PLGS) algorithm in the DIA:CONN G8. Forty people with type 1 diabetes mellitus (T1DM) who used a DIA:CONN G8 for at least 2 months with prior experience using pumps without and with PLGS were retrospectively analyzed. The objective was to assess the changes in time spent in hypoglycemia (percent of time below range [%TBR]) before and after using PLGS. The mean age, sensor glucose levels, glucose threshold for suspension, and suspension time were 31.1±22.8 years, 159.7±23.2 mg/dL, 81.1±9.1 mg/dL, and 111.9±79.8 min/day, respectively. Overnight %TBR <70 mg/dL was significantly reduced after using the algorithm (differences=0.3%, from 1.4%±1.5% to 1.1%±1.2%, P=0.045). The glycemia risk index (GRI) improved significantly by 4.2 (from 38.8±20.9 to 34.6±19.0, P=0.002). Using the PLGS did not result in a change in the hyperglycemia metric (all P>0.05). Our findings support the PLGS in DIA:CONN G8 as an effective algorithm to improve night-time hypoglycemia and GRI in people with T1DM.

Background:
To assess the quality of life (QoL) and treatment satisfaction with intermittently-scanned continuous glucose monitoring (isCGM) in women with gestational diabetes mellitus (GDM).
Methods:
This prospective observational study included 189 women with GDM who completed the Korean version of the Audit of Diabetes-Dependent Quality of Life Questionnaire (K-ADDQoL). Among them, 25 women who utilized isCGM between gestational weeks 30 and 34 completed the Korean version of the Diabetes Treatment Satisfaction Questionnaire change version (K-DTSQc) to evaluate their satisfaction with isCGM during pregnancy.
Results:
GDM had a negative impact on the perceived QoL in 89.4% of the women. All 19 domains of the K-ADDQoL were adversely influenced by GDM, with the most significant impact on the freedom to eat (weighted impact score, −6.98 ± 2.49, P < 0.001) and the least impact on the sex life (−0.25 ± 0.80, P = 0.008). Younger women and those treated with insulin perceived themselves as being more affected in their QoL due to GDM. Women perceived to have less effect on their QoL attributed to GDM exhibited higher ΔHbA1c one year after delivery (ΔHbA1c, 0.3 ± 0.4% vs. 0.0 ± 0.4% in less affected vs. more affected women). The utilization of isCGM improved treatment satisfaction (overall satisfaction score, 10.36 ± 9.21, P < 0.001), independent of glycemic control during pregnancy.
Conclusion
Although GDM negatively affects the perceived QoL during pregnancy, attentiveness to GDM management may have a positive impact on long-term glycemic control.Moreover, employing isCGM can enhance treatment satisfaction in women with GDM.
