context: It is estimated that half of unintended pregnancies could be averted if emergency contraception (Ec) were easily accessible and used. Objective: To e valuate the effect of direct access to Ec through pharmacies and advance provisi on on reproductive health outcomes. Design, Setting, and Participants: A randomi zed, sin-gle-blind, controlled trial (July 2001-June 2003) of 2117 women, age s 15 to 24 years, attending 4 california clinics providing family planning servi ces, who were not desiring pregnancy, using long-term hormonal contraception or requesting Ec. Intervention: Participants were assigned to 1 of the following g roups: (1) pharmacy access to Ec; (2) advance provision of 3 packs of levonorges trel Ec; or (3) clinic access (control). Main Outcome Measures: Primary outcomes were use of Ec, pregnancies, and sexually transmitted infections (STIs) assesse d at 6 months; secondary outcomes were changes in contraceptive and condom use a nd sexual behavior. Results: Women in the pharmacy access group were no more lik ely to use Ec (24.2%) than controls (21.0%) (P=.25). Women in the advance prov ision group (37.4%) were almost twice as likely to use Ec than controls (21.0% ) (Pcy of unprotected intercourse was similar (39. 8%vs 41.0%, respectively, P= .46). Only half (46.7%) of study participants wh o had unprotected intercourse used Ec over the study period. Eight percent of pa rticipants became pregnant and 12%acquired an STI; compared with controls, wome n in the pharmacy access and advance provision groups did not experience a signi ficant reduction in pregnancy rate (pharmacy access group: adjusted odds ratio [ OR], 0.98; 95%confidence interval [cI], 0.58-1.64; P=.93; advance provision gr oup: OR, 1.10; 95%cI, 0.66-1.84, P=.71) or increase in STIs (pharmacy access g roup: adjusted OR, 1.08,95%cI, 0.71 -1.63, P=.73; advance provision group: OR, 0.94, 95%cI, 0.62-1.44, P=.79).

The first search for the doubly heavy Ωbc0baryon and a search for the Ξbc0baryon are performed using pp collision data collected via the LHcb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 *** baryons are reconstructed via their decays to ∧c+π-andΞc+π-.No significant excess is found for invariant masses between 6700 and 7300 MeV/c2,in a rapidity range from2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ωbc0andΞbc0production cross-section times the branching fraction to ∧c+π-（Ξc+π-） relative to that of the ∧b0（Ξb0） baryon,for different lifetime hypotheses,at 95% confidence *** upper limits range from 0.5×10-4to 2.5×10-4for theΩbc0→∧c+π-(Ξbc0→∧c+π-) decay,and from 1.4×10-3to 6.9×10-3for the Ωbc0→Ξc+π-(Ξbc0→Ξc+π-) decay,depending on the considered mass and lifetime of the Ωbc0(Ξbc0) baryon.

BAcKGROUND: Transcranial Doppler ultrasonography that is aimed at residual obs tructive intracranial blood flow may help expose thrombi to tissue plasminogen a ctivator (t-PA). Our objective was to determine whether ultrasonography can saf ely enhance the thrombolytic activity of t-PA. METHODS: We treated all patients who had acute ischemic stroke due to occlusion of the middle cerebral artery wi th intravenous t-PA within three hours after the onset of symptoms. The patient s were randomly assigned to receive continuous 2-MHz transcranial Doppler ultra sonog(raphy the target group) or placebo(the control group). The primary combine d end point was complete recanalization as assessed by transcranial Doppler ultr asonography or dramatic clinical recovery. Secondary end points included recover y at 24 hours, a favorable outcome at three months, and death at three months. R ESULTS: A total of 126 patients were randomly assigned to receive continuous ult rasonography(63 patients) or placebo(63 patients). Symptomatic intracerebral hem orrhage occurred in three patients in the target group and in three in the contr ol group. complete recanalization or dramatic clinical recovery within two hours after the administration of a t-PA bolus occurred in 31 patients in the target group(49 percent), as compared with 19 patients in the control group(30 percent ; P=0.03). Twenty-four hours after treatment of the patients eligible for follo w-up, 24 in the target group(44 percent) and 21 in the control group (40 percen t) had dramatic clinical recovery(P=0.7). At three months, 22 of 53 patients in the target group who were eligible for follow-up analysis (42 percent) and 14 o f 49 in the control group(29 percent) had favorable outcomes (as indicated by a score of 0 to 1 on the modified Rankin scale)(P=0.20). cONcLUSIONS: In patients with acute ischemic stroke, continuous transcranial Doppler augments t-PA-indu ced arterial recanalization, with a nonsignificant trend toward an increas

Background: Multicentric squamous dysplasia is frequent in the esophagus and c an be visualized by chromoendoscopy(Lugol’s solution) as multiple Lugol-voidin g lesi- ons (LVLs).Although EMR commonly is used to treat superficial esophageal cance r, new lesions can arise and incomplete resection can result in residual disease . Little is known about the risk factors for local recurrence or the appropriate treatment for recurrent lesions. Methods: A total of 116 consecutive patients w ith a total of 165 esophageal squamous-cell carcinomaswere studied retrospectiv ely. Follow-up examination by means of chromoendoscopy(Lugol’s solution) and b iopsies was performed every 3 months during the first year after EMR and every 6 months thereafter. Lesions were defined as a local recurrence when cancer was d etected at the site of the EMR scar. Risk factors associated with local recurren ce were investigated by using logistic analysis. Results: At a median follow-up of 35 months (range 12-110 months), local recurrence was detected for 33(20%) of 165 lesions. Of the patient-related factors, multivariate logistic analysis showed that multiple LVLs (OR 3.1: 95%cI[1.1, 8.5]; p = 0.03) was an independe nt risk factor for local recurrence after EMR. The cumulative local recurrence r ates at 3 years in patients with multiple LVLs and those without multiple LVLs w ere 39%and 14%(pctively. All of the recurrent lesions except two could be removed by EMR,which was not associated with any serious complication. The remaining two patients had chemoradiotherapy. Overall causespecific surviva l at 3 years was 100%. conclusions: Patients with multiple LVLs are at risk of local recurrence after *** careful long-term endoscopic follow-up is needed for su- ch patients, EMR is potentially curative for recurrent lesions.

Objective To measure the change in vision and visual outcomes at 12 months aft er macular translocation with 360°retinectomy (MT360) and silicone oil tamponad e in patients with bilateral vision loss resulting from subfoveal choroidal neov ascular membranes in age-related macular degeneration (AMD). Design A prospecti ve, interventional, consecutive, noncomparative case series. Participants Sixty -four patients with bilateral vision loss resulting from neovascular AMD. Metho ds Eligible patients had AMD with subfoveal choroidal neovascularization in the operative eye and a maximum of 6 months of central vision loss. Preoperative and 12-month postoperative evaluations included standardized testing of near and d istance acuity and reading speed. Patients underwent MT360 with silicone oil tam ponade, followed 2 months later by extraocular muscle surgery and silicone oil r emoval. Main outcome measures change in distance acuity, near acuity, and readin g speed at 12 months after MT360 compared with those values before surgery. Resu lts Sixty-one patients were followed up for 12 months. All eyes were translocat ed successfully. Median distance acuity letter score improved from 62 letters (S nellen equivalent of approximately 20/125) before surgery to 69 letters (approxi mately 20/80) by 12 months after surgery (P=0.03). Median near acuity improved f rom 0.70 logarithm of the minimum angle of resolution (logMAR) units (approximat ely 20/100) before surgery to 0.44 logMAR units (approximately 20/55) at 12 mont hs (P ce acuity improved by 1 or more lines in 32 patients (52%).
