Characteristics of drowning deaths in an inner city river

A study was undertaken of all drowning deaths that occurred over a 30-year period from 1988 to 2017 in the urban section of the River Torrens, Adelaide, South Australia, an augmented waterway that runs through the central business district. Autopsy records from Forensic Science South Australia (FSSA) were reviewed. There were 34 drownings (0–5 cases/yr) with 28 males and 6 females (M;F = 4.6:1), with an age range for males of 18-76yrs (mean 42.0; SD 18.0) and for females of 20-84yrs (mean 69.3; SD 24.5). There were 15 (44%) accidents, 11 (32%) suicides, 1 (3%) homicide and 7 (21%) undetermined. Of the 22 cases during or after 1994 with complete toxicology reports, 10 (45%) had a blood alcohol concentration (BAC) of greater than 0.05% (g/100 mL) with an illicit substance detected in 4 (18%) cases: (MDMA (3,4-methylenedioxymethamphetamine), methylamphetamine and THC (delta-9-tetrahydrocannabinol) acid). The presence of various therapeutic drugs was also detected in 10 cases (45%) including temazepam, fluoxetine, diazepam, olanzapine, amitriptyline, carbamazepine, codeine, citalopram and valproate. Although the numbers of cases were not high, the urban portion of the River Torrens had a much higher number of drowning events per kilometre compared to other inland waterways in South Australia such as the Murray River. This is most likely due to the vulnerability that exists for intoxicated individuals in the city from falls into the water and to the availability of the river as a means of suicide to members of the adjacent urban population.     

Quality of life after single-incision laparoscopic cholecystectomy: A randomized,clinical trial

Background

Controversy continues as to whether single-incision laparoscopic cholecystectomy, with the somewhat larger incision at the umbilicus, may lead to a worse postoperative quality of life and more pain compared with the more classic 4-port laparoscopic cholecystectomy. The aim of this study was to compare single-incision and 4-port laparoscopic cholecystectomy from the perspective of quality of life.

Soul City: a sustainable edutainment vehicle facilitating social change

This paper outlines the programming model employed by the Soul City Institute for Health and Development Communication, a South African NGO, in using ‘edutainment’ to facilitate social change. The paper refers to the intersection of this model and current thought on health promotion and various social change theories. It also discusses key challenges and factors contributing to sustainability over 12 years.     

海口地区2000年临床分离菌耐药性监测

目的：监测海口地区临床分离菌对抗菌药物的耐药状况。方法：采用VITEK微生物自动分析仪测定药敏。结果：2000年共收集临床分离菌1399株，革兰阳性球菌426株（30．5％），革兰阴性杆菌973株（69．5％），以铜绿假单胞菌、大肠杆菌、金黄色葡萄球菌、肺炎克雷伯杆菌最多见，所监测的细菌总体耐药率比国内其他地区偏高，且出现万古霉素耐药的表皮葡萄球菌和粪肠球菌。结论：海口地区的细菌耐药严重，控制细菌耐药成为当务之急。     

内蒙古赤峰地区鼠疫现状和流行趋势预测及控制措施的研究

赤峰地区于１９４８￣１９９６年发现了１６６３２．２ｋｍ＾２鼠疫自然疫源地，分布于１１个旗（县、区）。目前达到控制鼠疫面积１３９１７．８ｋｍ＾２，占疫源地总面积的８３．６８％。选取与疫源地相关的１２种量经因子进行聚类分析，结果可分为：１．疫源性长存区；２．动物鼠疫间断流行区；３．鼠疫动物病控制区；４．疫源性基本消除区。同时对措施进行了探讨。     

Metabolic polymorphisms and the micronucleus frequency in buccal epithelium of adolescents living in an urban environment

Micronuclei and other biomarkers were evaluated in oral cells from 11- to 16-year-old girls living in a foster home in the central area of México City. Variables analyzed for possible association with these biomarkers include smoking habits, body mass index, metabolic polymorphisms for NAT1 and GSTM1 and whether the cells were obtained from the cheek or pharynx. The results indicated that individuals having the NAT1*10 homozygous genotype showed a significant increase in chromatin buds and binucleated cells. When the damage in the cheek was compared with damage in the pharynx, a significant increase in micronuclei and binucleated cells was found for the latter tissue in all the individuals analyzed.     

Membrane-associated proteins of T4-infected Escherichia coli

During the prereplicative period after the infection of Escherichia coli by phage T4, more than 50 proteins are synthesized. Many of them have been identified with their corresponding genes. Among them, at least 13 are selectively enriched in the membrane preparation. They include the products of the two rII genes, genes 39, 52 (DNA-delay), and others not yet identified. The majority of these proteins (90%) are extractable by the detergent, sarkosyl, and are possibly associated with the inner or cytoplasmic membrane. Based on their electrophoretic migration in SDS-polyacrylamide gels and on their tryptic fingerprints, these proteins are found to be phage induced. Two of the newly synthesized proteins that are selectively enriched in the cell wall or outer envelope fraction are found to be identical with two envelope proteins of the host cell. They are continually synthesized after phage infection although general host protein synthesis is shut off.     

2022年度遵义市67403例新生儿苯丙酮尿症筛查分析

目的：分析2022年遵义市67 403例新生儿苯丙酮尿症筛查结果。方法：选取2022年1月至2022年12月在遵义市出生并接受苯丙酮尿症筛查的67 403例新生儿为研究对象,收集其足跟血干血斑样本,采用荧光分析法测定干血斑中新生儿的苯丙氨酸指标水平,疑似阳性的新生儿进行进一步确诊。分析所有新生儿的苯丙酮尿症诊断情况。结果：2022年遵义市69 394例新生儿中总共有67 403例接受了苯丙酮尿症筛查,筛查率为97.13%,其中苯丙酮尿症的可疑阳性数为390例,可疑阳性召回率为100.00%。390例可疑阳性的新生儿中,确诊苯丙酮尿症的有7例,其中男性2例,女性5例,确诊率为0.010 39%。7例患儿中经典型苯丙酮尿症、中度苯丙酮尿症以及轻度高苯丙氨酸血症分别为1例（14.29%）、1例（14.29%）、5例（71.43%）。结论：2022年贵州省遵义市新生儿苯丙酮尿症筛查率为97.13%,苯丙酮尿症发生率为0.010 39%。
