High-quality data are needed to guide interventions aimed at improving breast cancer outcomes in sub-Saharan Africa. We present data from an institutional breast cancer database to create a framework for cancer policy and development in Nigeria. An institutional database was queried for consecutive patients diagnosed with breast cancer between January 2010 and December 2018. Sociodemographic, diagnostic, histopathologic, treatment and outcome variables were analyzed. Of 607 patients, there were 597 females with a mean age of 49.8 ± 12.2 years. Hydroxychloroquine purchase Most patients presented with a palpable mass (97%) and advanced disease (80.2% ≥ Stage III). Immunohistochemistry was performed on 21.6% (131/607) of specimens. Forty percent were estrogen receptor positive, 32.8% were positive for HER-2 and 43.5% were triple negative. Surgery was performed on 49.9% (303/607) of patients, while 72% received chemotherapy and 7.9% had radiotherapy. At a median follow-up period of 20.5 months, the overall survival was 43.6% (95% CI -37.7 to 49.5). Among patients with resectable disease, 18.8% (57/303) experienced a recurrence. Survival was significantly better for early-stage disease (I and II) compared to late-stage disease (III or IV) (78.6% vs 33.3%, P  less then  .001). Receipt of adjuvant radiotherapy after systemic chemotherapy was associated with improved survival in patients with locally advanced disease (68.5%, CI -46.3 to 86 vs 51%, CI 38.6 to 61.9, P  less then  .001). This large cohort highlights the dual burden of advanced disease and inadequate access to comprehensive breast cancer care in Nigeria. There is a significant potential for improving outcomes by promoting early diagnosis and facilitating access to multimodality treatment.Smith-Kingsmore syndrome (SKS) is a rare autosomal dominant disorder caused by heterozygous germline activating pathogenic variants in mammalian target of rapamycin (MTOR) on chromosome 1p36. A few patients with disseminated mosaicism have been described so far and they seem to display a different phenotype when compared to germline cases. Here we report the sixth case with a disseminated mosaic MTOR pathogenic variant, a 7-year-old boy with hemimegalencephaly, epilepsy, developmental delay, hypomelanosis of Ito, and lateralized overgrowth. Genetic testing revealed a pathogenic variant (c.4448G > A, p.Cys1483Tyr) in MTOR with a frequency of 32% in the DNA extracted from a skin sample, 3% in saliva and 0.46% in blood. The clinical features observed in our patient further corroborate the existence of differences in phenotypic presentation of germline and mosaic SKS cases. Moreover, lateralized overgrowth, a finding never described so far in SKS, further expands the phenotypic spectrum of SKS and allows the inclusion of MTOR pathogenic variants among the several causes of asymmetric body overgrowth.The intestinal environment is unique because it supports the intestinal epithelial cells under a normal oxygen environment and the microbiota under an anoxic environment. Due to importance of understanding the interactions between the epithelium and the microbiota, there is a strong need for developing representative and simple experimental models. Current approaches do not capture the partitioned oxygen environment, require external anaerobic chambers, or are complex. Another major limitation is that with the solutions that can mimic this oxygen environment, the oxygenation level of the epithelial cells is not known, raising the question whether the cells are hypoxic or not. We report standalone microfluidic devices that form a partitioned oxygen environment without the use of an external anaerobic chamber or oxygen scavengers to coculture intestinal epithelial and bacterial cells. By changing the thickness of the device cover, the oxygen tension in the chamber was modulated. We verified the oxygen levels using several tests microscale oxygen sensitive sensors which were integrated within the devices, immunostaining of Caco-2 cells to determine hypoxia levels, and genetically encoded bacteria to visualize the growth. Collectively, these methods monitored oxygen concentrations in the devices more comprehensively than previous reports and allowed for control of oxygen tension to match the requirements of both intestinal cells and anaerobic bacteria. Our experimental model is supported by the mathematical model that considered diffusion of oxygen into the top chamber. This allowed us to experimentally determine the oxygen consumption rate of the intestinal epithelial cells under perfusion.
During endoscopic submucosal dissection for superficial esophageal cancer, patient body movement can sometimes occur, which may cause discontinuation of the procedure. Propofol and dexmedetomidine have recently been found to be useful sedatives for endoscopic submucosal dissection. This study investigated whether sedation using propofol plus dexmedetomidine can suppress the patient's body movements during esophageal endoscopic submucosal dissection and compared this combination with sedation using propofol alone.

This was a prospective double-blind randomized controlled trial. Patients with superficial esophageal cancers who underwent esophageal endoscopic submucosal dissection at Yokohama City University Hospital were prospectively enrolled and were randomly assigned to the propofol and the propofol plus dexmedetomidine groups. The primary endpoint was the incidence of restlessness. The secondary endpoints were the satisfaction score, maintenance dose of propofol, and number of rescue propofol injections.

Sixty-six patients (propofol group n=33; combination group n=33) were included. The combination group had a significantly lower incidence of restlessness than the propofol group (3.0% vs 27.3%, P=0.02). In the combination group, the satisfaction scores of the endoscopists were significantly higher, the maintenance dose of propofol was significantly lower, and the number of rescue propofol injections was lower than those in the propofol group (3.0% vs 18.2%, P<0.001). Although the incidence of bradycardia was significantly higher in the combination group (30.3% vs 3.0%, P<0.01), no serious adverse effects occurred.

The propofol plus dexmedetomidine combination provided excellent sedation that effectively suppressed the patient's body movements during esophageal endoscopic submucosal dissection.
