ng.2799-F1Urothelial bladder cancer (UBC) is heterogeneous at the clinical, pathological and genetic levels. Tumor invasiveness (T) and grade (G) are the main factors associated with outcome and determine patient management1.

A discovery exome sequencing screen (n = 17), followed by a prevalence screen (n = 60), identified new genes mutated in this tumor coding for proteins involved in chromatin modification (MLL2, ASXL2 and BPTF), cell division (STAG2, SMC1A and SMC1B) and DNA repair (ATM, ERCC2 and FANCA). STAG2, a subunit of cohesin, was significantly and commonly mutated or lost in UBC, mainly in tumors of low stage or grade, and its loss was associated with improved outcome.

Loss of expression was often observed in chromosomally stable tumors, and STAG2 knockdown in bladder cancer cells did not increase aneuploidy. STAG2 reintroduction in non-expressing cells led to reduced colony formation. Our findings indicate that STAG2 is a new UBC tumor suppressor acting through mechanisms that are different from its role in preventing aneuploidy.

tt0242308Background - Feelings of depression may contribute to persistent smoking during pregnancy. Relationships between feelings of depression, smoking behavior and educational level during pregnancy have been documented. So far, however, there have been no longitudinal studies assessing feelings of depression in women with different smoking patterns antepartum and postpartum. Objectives – The aim of this study was to determine relationships between depressive symptoms, socio-demographic characteristics and smoking pattern during and after pregnancy. Methods – We conducted an observational, prospective, non-interventional study. Data were collected during two stages of pregnancy (T0: < 16 weeks and T1: 32-34 weeks) and postpartum (T2: > 6 weeks) in 523 respondents. Feelings of depression (according to the Beck Depression Inventory - BDI), smoking behavior and socio-demographic variables were registered and analyzed using generalized linear mixed models (SAS 9.2). Results - At all sampling points smokers and initial smokers reported significantly more depressive symptoms compared to recent ex-smokers, non-smokers and initial non-smokers (F(4,486) = 12.06; p < .001). The three-way interaction between time point, smoking pattern and educational level (F(8,619) = 2.29; p = 0.02) was significant. The evolution of the mean BDI over time differed between the educational level classes of the smokers. Within respondents with a secondary school certificate or less differences were observed between smokers and non-smokers, recent ex-smokers and initial non-smokers, and non-smokers and initial non-smokers. Within the respondents with a college or university degree no differences were observed. Discussion – Paying attention to depressive symptoms and offering adapted stop-smoking advice to lower educated pregnant women and their smoking partners might reduce the prevalence of smoking among pregnant and postpartum women.

bld092319Purpose
A better understanding of the factors contributing to smoking cessation would be of substantial benefit to public health. The purpose of this study was to identify significant predictors of successful smoking cessation in the Korean population.

Methods
We compared 1,181 successful quitters with 940 current smokers who made a recent attempt to quit but failed in the past 12 months using the fourth Korea National Health and Nutrition Examination Survey. We examined the relationship of sociodemographic, behavioral and environmental characteristics, comorbid conditions, and quitting methods to successful smoking cessation.

Results
Older age, female, being married, having higher education, having a lower level of stress, having smoked 20 or more cigarettes per day, and one's own will for quitting have been identified as significant determinants of successful cessation. Frequency of alcohol consumption and trying numerous quitting methods was inversely related to stopping smoking.

Conclusion
This study suggests that cessation programs need to take a holistic approach and should consider these factors in setting up.

lemonade_166x138_BC78XB"Best cure for a hangover? Sprite," claims The Daily Telegraph and the Mail Online. But the popular fizzy lemon and lime drink may not be the morning-after quick-fix for boozers that the media suggests it is.

The headlines are based on a Chinese laboratory study that measured the effect of different drinks on the speed liver enzymes metabolise alcohol. Out of 57 drinks tested, researchers found that only two drinks increased the speed of two liver enzymes that reduce the amount of the toxic chemical acetaldehyde. This chemical is produced when our bodies break down alcohol.

The first drink was called "hui yi su da shui" (probably a type of soda water) and the second was called "xue bi" (probably Sprite, although the study did not report that either of these drinks were the popular drink known as Sprite).

rds184268Background: The prevalence of tobacco smoking among homeless people can reach more than 90%, with related
morbidity and mortality being high. However, research in this area is scarce. This study aims to explore smoking and
quitting related behaviours, experiences and knowledge in homeless smokers in the context of other substance abuse.

Methods: Face-to-face interviews were conducted with homeless smokers accessing a harm reduction service in
Nottingham, UK. Data on smoking history, nicotine dependence, motivation and confidence to quit were collected
using structured instruments; a semi-structured interview guide was used to elicit responses to predefined subject
areas, and to encourage the emergence of unprecedented themes. Data were analysed using framework analysis and
descriptive statistics.

ucsi001959Objective
To identify possible predictors of post-cessation weight gain in smoking abstainers.

Patients and methods
A sample of 607 successful abstainers seen at the Centre for Tobacco-Dependent in Prague, Czech Republic, between 2005 and 2010, was included in this analysis. This sample was followed up for 1 year and included 47.9% women (N = 291) with the mean age of 48 years (18–85).

Findings
Post-cessation weight gain occurred in 88.6% of the 607 abstainers. The mean weight gain after one year post-quit was 5.1 kg (95% confidence interval 4.7–5.5 kg). Baseline characteristics associated with increased weight gain included a higher baseline smoking rate (p < 0.001), more severe cigarette dependence (p = 0.003), less physical activity (p = 0.008), and a report of increased appetite on the baseline assessment of withdrawal symptoms (p < 0.001).

tt6200265Abstract
Residential treatment for substance use disorders (SUD) provides opportunity for smoking intervention. A randomized controlled trial compared: (1) motivational interviewing (MI) to brief advice (BA), (2) in one session or with two booster sessions, for 165 alcoholics in SUD treatment. All received nicotine replacement (NRT). MI and BA produced equivalent confirmed abstinence, averaging 10% at 1 month, and 2% at 3, 6 and 12 months. However, patients with more drug use pretreatment (> 22 days in 6 months) given BA had more abstinence at 12 months (7%) than patients in MI or with less drug use (all 0%). Boosters produced 16–31% fewer cigarettes per day after BA than MI. Substance use was unaffected by treatment condition or smoking cessation. Motivation to quit was higher after BA than MI. Thus, BA plus NRT may be a cost-effective way to reduce smoking for alcoholics with comorbid substance use who are not seeking smoking cessation.

fan2026431Ethnicity is a biological and a social construct which encompasses ancestral genes, cultural, geographic and socioeconomic characteristics shared within a population. It is clear that no homogeneous racial groups exist within the human race as demonstrated when examining ancestry informative markers. Both the genetic and non-genetic components of ethnicity exert influence in the expression and outcome of systemic lupus erythematosus (SLE), including disease activity, damage accrual, work disability and mortality.

Although it is difficult to determine the extent to which the differences observed in these parameters are caused by genetic or non-genetic factors, early in the disease genetic factors seem to play a more important role as determinants of the differences observed between SLE patients from various ethnic groups. Over the course of the disease, non-genetic factors seem to play a more important role. By and large, SLE is more frequent and more severe with higher disease activity and more damage accrual in non-Caucasian populations (Hispanics, African descendants and Asians) than in Caucasians. To overcome these differences it is necessary to optimize health care access to disadvantaged populations and use innovative tools to increase disease awareness and improve treatment adherence.

spl016838Pregnancy poses an important challenge for doctors looking after women with systemic lupus erythematosus. Knowledge about safety of medications, the effect of pregnancy on such disease, and vice versa, together with multidisciplinary team care, are basic cornerstones needed to provide the best obstetric and medical care to these women.

Pre-conceptional counselling constitutes the ideal scenario where a patient's previous obstetric history, organ damage, disease activity, serological profile and additional medical history can be summarised. Important issues regarding medication adjustment, planned scans and visits, and main risks discussion should also be raised at this stage. Planned pregnancies lead to better outcomes for both mothers and babies. Close surveillance throughout pregnancy and the puerperium, and tailored management approach guarantee the highest rates of successful pregnancies in these women.

rds175149In the 12 months to May 2013 there were 6,334 hospital admissions for dog bites or strikes, a fall of 1.9 per cent from the 12 months to May 2012 where there were 6,454.

Today's report from the Health and Social Care Information Centre (HSCIC) shows that Yorkshire and the Humber had the second highest number of admissions for dog bites or strikes (14.6 per cent or 925 admissions) and admissions were lowest in the South East Coast (3.6 per cent or 229 admissions).

The report also covers hospital admissions for bites, strikes and stings from other mammals, non-venomous arthropods, hornets, wasps and bees in addition to dog bites or strikes.The figures show there were 58.3 per cent fewer admissions for stings from hornets, wasps or bees compared to the 12 months to May 2012 (552 compared to 1,324).

The figures are from a special topic on bites, strikes and stings due to certain animals and insects presented as part of the monthly provisional Hospital Episode Statistics publication, which shows admissions data broken down by patient demographics, region and type of injury.
