RESUMEN
ObjectiveTo investigate the prevalence of overweight， obesity and fatty liver disease （FLD） in adult residents in a suburban area of Shanghai， and to explore the relationship between these conditions and eating out of home （EOH）. MethodsAdult residents from Zhongshan Street， Songjiang， Shanghai， were invited to report their frequency of EOH and undergo a physical examination using B-ultrasonography from May to September 2017. Binary logistic regression analyses were conducted to examine the relationship between EOH and conditions of overweight， obesity， and FLD. ResultsAmong the final sample size of 6 608 participants， the prevalence rates of overweight， obesity， and FLD were 41.65%， 14.71% and 38.29%， respectively. After adjusting for potential confounders， logistic analyses revealed that participants with an EOH frequency > once/week had a 1.44-fold higher prevalence of obesity （P=0.006）， a 1.35-fold higher prevalence of overweight/obesity （P=0.005）， and a 1.36-fold higher prevalence of FLD （P=0.008）. ConclusionThe prevalence of overweight， obesity， and FLD is relatively high in Songjiang， Shanghai. EOH may be a risk factor for these diseases， and residents are recommended to reduce the frequency of EOH.
RESUMEN
Objective To investigate the feasibility and efficacy of transurethral prostate enucleation with 2 μm laser in the treatment of benign prostatic hyperplasia (BPH). Methods One hundred and seven patients with BPH were treated by transurethral prostate enucleation with 2 μm laser under continuous epidural anesthesia or laryngeal mask anesthesia. The patient′s, average age was 67±9 yrs (52 to 85 yrs). Of whom, 10 patients had a history of urinary retention. The mean prostate volume was 72.5±17.6 ml (45 to 158 ml). Two deep trenches were cut at the 5 and 7 o, clock position from the bladder neck to the verumontanum. The incision continued to the urethral mucosa and submucosa along with the verumontanum bilaterally in an arc-shape and ended at the internal arc of urethral sphincter. Then the urethral mucosa at the level of the verumontanum was cut and the surgical capsule plane was identified. A retrograde blunt dissection was made along the surgical capsule plane with the resectoscope sheath front-end, and the sheath was swung from side to side to extend the capsule plane. The significantly enlarged middle lobe was treated with laser vaporization resection. In the same way, a trench was made at the 12 o, clock position, and the lateral lobe were removed by the sheath from the verumontanum level, finally only two cord-like pedicles were kept at the 1 and 11 o, clock position at the bladder neck, so that the removed gland tissue was fixed and hung in the gland fossa. For prostate volume less than 60 ml, the laser vaporization resection was carried out directly. If the prostate volume was greater than 60ml, transurethral resection would be performed instead of laser vaporization resection. With 4% mannitol irrigation, the enucleated prostate tissue was then cut into small pieces and washed out by a Braun plastic bottle through the resectoscope sheath. Intraoperative bleeding, operative time, catheterization time, postoperative voiding status, maximum urinary flow rate (Qmax) and length of hospital stay were recorded and analyzed. Results All patients successfully completed the transurethral prostate enucleation. The average operative time was 74±12 min (45-150 min). Five cases required blood transfusion. There was no recorded urethral stricture and no urinary incontinence except for one patient who recovered 1 mon after the operation. The follow-up time was 2-6 mon. The average Qmax was 6.3±0.6 ml/s before and increased to 17.5±1.5 ml/s after the operation. The international prostate symptom score (IPSS) and quality of life (QOL) were reduced from 26.4±5.5 and 4.6±0.5 to 9.3±2.1 and 2.8±0.3 after the operation, respectively, P<0.01. Postoperative secondary bleeding was not observed. Conclusions Transurethral prostate enucleation with 2 μm laser for BPH is a safe and effective minimally invasive treatment. Its efficacy is superior to open surgery, and even better than TURP.
RESUMEN
Objective:To assess the clinical utility of a fluorescence in situ hybridization(FISH) assay as a non-invasive method for diagnosing and monitoring urothelial carcinoma(UC) in the upper urinary tract(UUT).Methods:Urine specimens from 63 consecutive patients with UUT-UC and 69 controls with benign disease were analyzed by means of cytology and FISH.For FISH analysis,labeled probes specific for chromosomes 3,7,and 17 and for the p16(9p21) gene were used to assess chromosomal abnormalities indicative of malignancy.Sensitivity and specificity of both techniques were determined and compared.The frequency of chromosomal aberrations of malignant cells from UUT-UC was also determined.Results:Of 63 patients with UUT-UC,FISH affords an overall sensitivity of 84.1%(53/63),the figure being 71.4%(20/28)for PTa and PT1 tumors,94.3%(33/35) for PT2-4 tumors.The sensitivities of urine cytology were 35.7%(10/28)for PTa and PT1 tumor,45.7%(16/35)for PT2-4 tumors,with an overall sensitivity of 41.3%(26/63).The sensitivities of the two methods for the low grade tumors were 80%(20/25)and 44%(11/25),and for high grade tumors were 86.8%(33/38)and 39.5%(15/38),respectively.Specificities for FISH and urine cytology were 91.3%(63/69)and 94.2%(65/69)respectively.Conclusion:According to the results,the sensitivity of FISH for the detection of UUT-UC is superior to that of urine cytology and the specificities of FISH and urine cytology are not significantly different.FISH can promote the diagnosis of UUT-UC,especially for the low stage and low grade cases,it may be a new promising non-invasive method for the diagnosis of UUT-UC.
