Incidence and ultrasonographic characteristics of cesarean scar niches after uterine closure by double-layer barbed suture: A prospective comparative study.

OBJECTIVE: To compare the ultrasonographic features of uterine scars and clinical symptoms after cesarean delivery (CD) using barbed and conventional smooth sutures. METHODS: This case-control study enrolled women who underwent primary CD at 37 weeks of pregnancy or later. The uterus was closed using either double-layer unidirectional barbed suture or conventional double-layer smooth suture. Ultrasound scans of the uterine scar and evaluations of menstrual patterns were performed at 6, 12, and 24 months after surgery. RESULTS: In all, 102 patients underwent uterine closure with barbed suture, while 135 patients underwent smooth suture. At 6 months, patients in the barbed group had a lower incidence of uterine niches (20.2% vs 32.6%) that were also shallower in depth (P < 0.001). Lower incidence of niches was also observed in the barbed group at 12 and 24 months (P = 0.043 and 0.048, respectively). At these two follow-up times, the smooth group had a higher number of patients reporting postmenstrual spotting (P < 0.05) and more postmenstrual spotting days per month (P < 0.050). CONCLUSION: The use of double-layer barbed suture during CD was associated with a lower incidence of scar niches and a more favorable menstrual pattern compared with the use of smooth suture.

Tailored repetitive transcranial magnetic stimulation for depression and addictions.

Transcranial magnetic stimulation (TMS) has been widely applied for evaluation of the cortical eloquence through creation of the temporary "virtual lesion" allowing assessment of the evaluated function within the targeted region, which may be also employed for management of mental symptoms or modification of the abnormal behavior. It is believed that this non-invasive neuromodulation modality has a double impact on neurons-primary modulation of electrical activity and stimulation of neuroplasticity; the latter can be facilitated by repeated administration of TMS during multiple sessions over sufficiently long periods of time to induce consolidation of treatment effects through their recall at psychological, physiological, and cellular levels. These principles were employed in our data-driven, tailored strategy based on the modifications of TMS protocol and its adaptation to newly appearing changes of the clinical situation along with administration of prolonged and/or repeated courses of therapeutic stimulation, which showed high efficacy resulting in complete relief of depressive symptoms or substance use in 75% of treated patients at 1-year follow-up. Such results justify application of repetitive TMS for management of psychiatric disorders and warrant additional evaluation of its efficacy in further clinical studies.
