Who suggests drinking less? Demographic and national differences in informal social controls on drinking

Objective: The purpose of this study was to examine variation in reports of pressuring others to drink less, as a form of informal social control of drinking, across countries and different types of relationship to the respondent. Method: A cross-sectional survey was administered to 19,945 respondents ages 18-69 years in 14 countries included in the data set of the Gender, Alcohol and Culture: An International Study (GENACIS). Outcome variables were respondents' reports of pressuring others to drink less (yes/no) across a variety of relationships (their partners, other family members, workmates, or friends). Multilevel, multivariable logistic regression analysis was carried out on each outcome variable. The fixed-effects components included the Level 1 (individual) covariates of respondent age, gender, drinking status, and education level as well as the Level 2 (country level) covariates of percentage female drinkers and purchasing power parity. The random-effects components included country and current drinking status. Results: Respondents most frequently reported pressuring male friends to drink less (18%), followed by male family members (other than partners, 15%), partners (15%), work colleagues (12%), female friends (9%), female family members (other than partners, 6%), and children (5%). There was marked variation across countries, with pressuring frequently reported in Uganda, Costa Rica, and Nicaragua across most relationship types. Multivariable logistic regression revealed consistent effects of gender, with women more likely than men to report pressuring others to drink less across most relationship types. The patterns in relation to education status and age were less consistent and varied across relationship type. Conclusions: Informal social control of drinking varies dramatically according to whom is most likely to pressure whom to drink less as well as the country in which people live

Recovery of viral RNA and infectious foot-and-mouth disease virus from positive lateral-flow devices

Foot-and-mouth disease Virus (FMDV) is an economically important, highly contagious picornavirus that affects both wild and domesticated cloven hooved animals. In developing countries, the effective laboratory diagnosis of foot-and-mouth disease (FMD) is often hindered by inadequate sample preservation due to difficulties in the transportation and storage of clinical material. These factors can compromise the ability to detect and characterise FMD virus in countries where the disease is endemic. Furthermore, the high cost of sending infectious virus material and the biosecurity risk it presents emphasises the need for a thermo-stable, non-infectious mode of transporting diagnostic samples. This paper investigates the potential of using FMDV lateral-flow devices (LFDs) for dry transportation of clinical samples for subsequent nucleic acid amplification, sequencing and recovery of infectious virus by electroporation. FMDV positive samples (epithelial suspensions and cell culture isolates) representing four FMDV serotypes were applied to antigen LFDs: after which it was possible to recover viral RNA that could be detected using real-time RT-PCR. Using this nucleic acid, it was also possible to recover VP1 sequences and also successfully utilise protocols for amplification of complete FMD virus genomes. It was not possible to recover infectious FMDV directly from the LFDs, however following electroporation into BHK-21 cells and subsequent cell passage, infectious virus could be recovered. Therefore, these results support the use of the antigen LFD for the dry, non-hazardous transportation of samples from FMD endemic countries to international reference laboratories
