This split-mouth, randomized, double-blind clinical trial evaluated the efficacy of transcutaneous electrical nerve stimulation (TENS) in managing pain, edema, and trismus following the surgical removal of impacted mandibular third molars. 
Thirty-seven patients with bilaterally impacted third molars received TENS on one side immediately after surgery (50 Hz, 100-µs pulse, 15 minutes for 6 days), while the contralateral side received a placebo treatment. Pain scores, the primary outcome, were recorded for 7 days postoperatively, while edema and trismus were assessed on days 2, 4, and 7.
Results indicated that the TENS group experienced significantly lower pain scores compared to the placebo group (P<0.05), with reduced analgesic consumption during the first three days post-surgery (P<0.001). Although postoperative edema was lower in the TENS group, this reduction was not statistically significant (P>0.05). Trismus, measured by inter-incisal distance, showed no significant difference on day 2 but was significantly improved in the TENS group thereafter (P<0.001).
TENS proved effective in reducing postoperative pain and trismus following impacted third molar surgery, supporting its use as a non-pharmaceutical intervention to alleviate postoperative symptoms and enhance recovery.
 

According to a recent study, the administration of fifty mg of Vibegron once daily for twelve weeks exhibited significant improvement in bladder storage symptoms related to overactive bladder (OAB) following laser vaporization of the prostate for symptomatic benign prostatic hyperplasia when compared to the untreated follow-up period. The findings of this study were published in the journal, Lower Urinary Tract Symptoms.Split into two groups: one group received Vibegron 50 mg once daily, while the other group had no treatment and were only followed up for 12 weeks.The median age (interquartile range) was 75.5 (72.5-78.5) years for the Vibegron group, while it was 76.5 (71.0-81.0) years for the control group. At twelve weeks post-randomization, the intergroup difference in the mean change (95% CI) in twenty-four hour urinary frequency was -3.66 (-4.99, -2.33) with a significant decrease in the Vibegron group. Significant improvements were noted in the International Prostate Symptom Score, Overactive Bladder Questionnaire score, Overactive Bladder Symptom Score, and IPSS storage score for the Vibegron group. Additionally, in the Vibegron group the voided volume per micturition increased.
Therefore, the treatment with fifty mg of Vibegron once a day for a duration of twelve weeks resulted in notable enhancement in bladder storage symptoms associated with overactive OAB after laser vaporization of the prostate for symptomatic benign prostatic hyperplasia when compared to the untreated follow-up period.
 

This double-blind, randomized, controlled trial examined the impact of vitamin D supplementation on anemia management in hemodialysis (HD) patients with end-stage renal disease (ESRD) and vitamin D deficiency. 
One hundred anemic HD patients with vitamin D deficiency were randomly assigned to receive either monthly vitamin D (50,000 IU) or a placebo for six months. Serum 25-hydroxyvitamin D (25(OH)D) levels were measured at baseline and after six months, while hemoglobin (Hb) concentrations were monitored monthly.
Results demonstrated that vitamin D supplementation significantly increased 25(OH)D levels in the treatment group compared to the placebo group (p > 0.001). While serum ferritin, serum iron, and transferrin saturation did not differ significantly between the groups, Hb concentrations in the vitamin D group rose significantly more than in the placebo group throughout the study period. 
Additionally, erythropoietin (EPO) dosage requirements were notably lower in the vitamin D group compared to the placebo group (p > 0.001).
These findings indicate that vitamin D supplementation is a safe and effective approach to improving anemia in HD patients with vitamin D deficiency, reducing the need for EPO therapy, and enhancing overall anemia management in this vulnerable population.

A new study reveals immune signatures that predict the effectiveness of subcutaneous immunotherapy (SCIT) in allergic rhinitis (AR) patients with house dust mite allergies. The research aimed to identify biomarkers that could enhance clinical outcomes by distinguishing SCIT responders from nonresponders.
The study analyzed circulating T and B cell subsets, serum immunoglobulin levels, and combined symptom and medication scores (CSMS) in two cohorts: a discovery group (Tongji cohort, n=72) and a validation group (Wisco cohort, n=43). SCIT responders were defined by a ≥30% improvement in CSMS after 12 months.
Key findings indicate that SCIT responders exhibited higher baseline levels of allergen-specific IgE (sIgE)/total IgE (tIgE) ratio, Type 2 helper T (TH2) cells, Type 2 follicular helper T (TFH2) cells, and memory B cell subtypes (CD23+ nonswitched memory B cells and switched memory B cells), along with lower follicular regulatory T cells (TFR) and TFR/TFH2 cell ratio. 
Using random forest and logistic regression algorithms, three key biomarkers- sIgE/tIgE ratio, TFR/TFH2 ratio, and CD23+ B memory cell frequency, were identified as significant predictors of SCIT response. 
The predictive model demonstrated high accuracy (AUC = 0.899 in Tongji; AUC = 0.893 in Wisco), underscoring the potential of personalized immunotherapy approaches for AR patients based on immune signatures. 
These findings offer a promising step towards optimizing SCIT efficacy through biomarker-based treatment plans.
