To determine whether treatment of patients with large (>15 mm) impacted upper ureteral stones depended on stone location, we prospectively evaluated the therapeutic outcomes, complications, safety, and effectiveness of percutaneous nephrolithotomy (PCNL) and ureteroscopic lithotomy (URSL) in patients with stones higher and lower than the upper border of the fourth lumbar vertebra. Of the 174 patients analyzed, 83 (47.7%) underwent PCNL and 91 (52.3%) underwent URSL; all patients were followed up 1 month later and every 6 months for 18 months. Mean operation time (108.76±19.36 vs. 63.56±16.38 minutes, p<0.05) and postoperative hospital stay (2.49±1.23 vs. 5.36±1.98 days, p<0.05) were significantly longer in the PCNL than in the URSL group. The overall stone-free rates after 1 month were 96.4% and 75.8%, respectively, differing significantly for stones higher (97.8% vs. 57.5%, p<0.05) but not lower (94.7% vs. 90.2%) than the upper border of the fourth lumbar vertebra. The stone-retropulsion rate of URSL differed significantly for stones higher and lower than the upper border of the 4th lumbar vertebra (47.5% vs. 9.8%, p<0.05). Postprocedural complication rates were comparable in the URSL and PCNL groups, although the rate of auxiliary or salvage procedures was higher in the URSL group. The efficiency quotients (EQ) for PCNL and URSL were 0.93 and 0.59, respectively, with EQs in the URSL group differing significantly for stones higher and lower than the upper border of the fourth lumbar vertebra (0.40 vs. 0.82, p<0.05). Our findings indicate that treatment of impacted upper ureteral stones is dependent on stone location relative to the upper border of the fourth lumbar vertebra. URSL is unsuitable for stones at a higher location, whereas URSL and PCNL were equally effective for stones at a lower location.

To determine the safety and efficacy of radiofrequency ablation (RFA) for selective fetal reduction in complex monochorionic multiple pregnancies. From July 2011 to January 2015, data on all cases treated with RFA were collected prospectively in our hospital. Indications, procedure details, cause of fetal demise and pregnancy outcomes were analyzed. Sonography and magnetic resonance imaging were performed to detect fetal brain damage. Information regarding development after birth was collected according to the Gesell Development Schedule^®. There were 22 cases of twins (6 presenting with twin-twin transfusion syndrome, 10 with malformations, 4 with selective intrauterine growth restriction, and 2 with twin reversed arterial perfusion sequence); and 11 cases of triplets (9 dichorionictriamniotic, 2 monochorionictriamniotic). All surgeries were completed with one puncture. No maternal complications presented during RFA procedure, and the PPROM rate before 32 w was 9% (3/33). There were 3 cases of intrauterine fetal demise and 4 twin cases where pregnancy was terminated. The fetal survival rate was 77% (17/22) in twins, 91% (20/22) in triplets. Total fetal survival rate was 84% (37/44). The neurodevelopmental follow-up investigations showed no abnormalities in any of the survivors. RFA for selective fetal reduction in complex monochorionic multiple pregnancies is effective, minimally invasive, and safe.

Pontine autosomal dominant microangiopathy and leukoencephalopathy (PADMAL) is a rare hereditary cerebral small vessel disease. We report a novel collagen type IV alpha 1 (COL4A1) gene mutation in a Chinese family with PADMAL. The index case was followed up for 6 years. Neuroimaging, whole-exome sequencing, skin biopsy, and pedigree analysis were performed. She initially presented with minor head injury at age 38. MRI brain showed chronic lacunar infarcts in the pons, left thalamus, and right centrum semiovale. Extensive workup was unremarkable except for a patent foramen ovale (PFO). Despite anticoagulation, PFO closure, and antiplatelet therapy, the patient had recurrent lacunar infarcts in the pons and deep white matter, as well as subcortical microhemorrhages. Whole-exome sequencing demonstrated a novel c.*34G > T mutation in the 3′ untranslated region of COL4A1 gene. Skin biopsy subsequently demonstrated thickening of vascular basement membrane, proliferation of endothelial cells, and stenosis of vascular lumen. Three additional family members had gene testing and 2 of them were found to have the same heterozygous mutation. Of the 18 individuals in the pedigree of 3 generations, 12 had clinical and MRI evidence of PADMAL. The mechanisms of both ischemic and hemorrhagic stroke are likely the overexpression of COLT4A1 in the basement membrane and frugality of the vessel walls. Our findings suggest that the novel c.*34G > T mutation appears to have the same functional consequences as the previously reported COL4A1 gene mutations in patients with PADMAL and multi-infarct dementia of Swedish type.

Introduction: Music interventions can alleviate patient anxiety and improve post-surgical satisfaction. However, it remains uncertain whether personal music preferences affect efficacy. The authors tested whether personal music intervention with patient-selected songs played ad libitum is more effective than standard therapist-designed treatment with classical music. Methods: A prospective, parallel-group, single-blinded, randomized controlled trial with 229 participants (aged 18–60 years) previously scheduled for elective surgery. Data analyses followed a modified intention-to-treat principle. The patients were randomized into three groups: Standard care without music (Control), therapist-designed classic music treatment (TT), or personal music intervention with patient-selected songs played ad libitum by the patient (PI). All patients received standard post-anaesthesia care, and music intervention was started upon arrival at the post-anaesthesia care unit. Primary outcomes were anxiety and overall satisfaction at discharge. In contrast, secondary outcomes were systolic blood pressure during music intervention, the sleep quality of the night after surgery, and the occurrence of postoperative nausea and vomiting within the first 24 h after surgery. Results: Compared with therapist-designed music treatment, personal intervention decreased systolic blood pressure (T₀: 124.3±13.7, 95% CI:121–127.7; T_20min: 117.6±10.4, 95% CI:115–120.1; T_30min: 116.9±10.6, 95% CI:114.3–119.4), prevented postoperative nausea and vomiting (Control: 55.9%, TT: 64.6%, PI: 77.6%), including severe postoperative nausea (VAS score>4; Control: 44.1%; TT: 33.8%; PI: 20.9%) and severe emesis (Frequency≥3, Control: 13.2%; TT: 7.7%; PI: 4.5%). None of the treatments affected sleep quality at night after surgery (Median, Q1–Q3, Control: 3, 1–3; TT: 3, 1–4; PI: 3, 1–3.5). Personal, but not therapist, music intervention significantly prevented anxiety (Control: 36.4±5.9, 95% CI:35.0–37.9; TT: 36.2±7.1, 95% CI: 34.4-37.9; PI: 33.8±5.6, 95% CI: 32.4–35.2) and emesis (Control: 23.9%; TT: 23.4%; PI: 13.2%) and improved patient satisfaction (Median, Q1–Q3, C: 8, 6–8; TT: 8, 7–9; PI: 8, 7–9). Conclusions: Personal music intervention improved postoperative systolic blood pressure, anxiety, nausea, emesis, and overall satisfaction, but not sleep quality, as compared to therapist-designed classic intervention.

Background: Ovarian damage and follicle loss are major side effects of chemotherapy in young female patients with cancer. However, effective strategies to prevent these injuries are still lacking. The purpose of this study was to verify low-intensity pulsed ultrasound (LIPUS) can reduce ovarian injury caused by chemotherapy and to explore its underlying mechanisms in mice model. Methods: The mice were randomly divided into the Control group, Cisplatin group, and Cisplatin + LIPUS group. The Cisplatin group and Cisplatin + LIPUS group were intraperitoneally injected with cisplatin every other day for a total of 10 injections, and the Control group was injected with saline. On the second day of each injection, the Cisplatin + LIPUS group received irradiation, whereas the other two groups received sham irradiation. We used a variety of biotechnologies to detect the differences in follicle count, granulosa cell apoptosis, fibrosis, transcriptome level, oxidative damage, and inflammation in differently treated mice. Result: LIPUS was able to reduce primordial follicle pool depletion induced by cisplatin and inhibit the apoptosis of granulosa cells. Transcriptomic results confirmed that LIPUS can reduce ovarian tissue injury. We demonstrated that LIPUS can relieve ovarian fibrosis by inhibiting TGF-β1/Smads pathway. Meanwhile, it can reduce the oxidative damage and reduced the mRNA levels of proinflammatory cytokines caused by chemotherapy. Conclusion: LIPUS can reduce the toxic effects of chemotherapy drugs on ovaries, inhibit ovarian fibrosis, reduce the inflammatory response, and redcue the oxidative damage, reduce follicle depletion and to maintain the number of follicle pools.
