Aims: To assesses the extent of the gender gap among the treated population of drug users across Europe.Methods: This analysis reports data on 363,170 clients from 4647 treatment units in 23 countries (22 European Union member states and Switzerland). Findings: Overall, males outnumber females by four, but the gender ratio varies not only by geographical region/country, but also by drug. In the majority of countries, the most common primary problem drug is opioids, and the overall gender ratio mirrors the gender ratio of opioid users. In some countries, a considerable proportion of treated drug users have cannabis and stimulants (cocaine/amphetamines/ methamphetamines) as primary problem drugs. Stimulants other than cocaine and other drugs have lower, while cannabis has a higher than overall male-to-female gender ratio. Conclusions: The very high male-to-female gender ratios may reveal differential access to treatment. Our findings highlight the need to assess access to treatment for women problem drug users and to make women-focussed programmes more available to increase the proportion of women in drug treatment programmes across Europe.

Field experiments of 42.7 / 128.1 Gb/s WDM-OTDM transmultiplexing and all-optical dual-wavelength regeneration at the OTDM rate are presented. By using the asynchronous retiming scheme, we achieve error-free buffer-less data grooming with time-slot interchange (TSI) capability for OTDM meshed networking. We demonstrate excellent performance from the system, discuss scalability, applicability, and the potential reach of the asynchronous retiming scheme for transparent OTDMdomain interconnection.

Background-Aim. Although sleep disturbance is a common complaint among patients of all ages, research suggests that older adults are particularly vulnerable. The aim of this retrospective study was to elucidate the influence of age on clinical characteristics and polysomnographic findings of obstructive sleep apnea syndrome (OSAS) between elderly and younger male patients in a Greek population. Methods. 697 male patients with OSAS were examined from December 2001 to August 2011. All subjects underwent an attended overnight polysomnography (PSG). They were divided into two groups: young and middle-aged (<65 years old) and elderly (≥65 years old). We evaluated the severity of OSAS, based on apnea-hypopnea index (AHI), and the duration of apnea-hypopnea events, the duration of hypoxemia during total sleep time (TST) and during REM and NREM sleep, and the oxygen saturation in REM and in NREM sleep. Results. PSG studies showed that elderly group had significant higher duration of apnea-hypopnea events, longer hypoxemia in TST and in NREM sleep, as well as lower oxygen saturation in REM and NREM sleep than the younger group. Otherwise, significant correlation between BMI and neck circumference with AHI was observed in both groups. Conclusions. The higher percentages of hypoxemia during sleep and longer duration of apnea-hypopnea events that were observed in the elderly group might be explained by increased propensity for pharyngeal collapse and increased deposition of parapharyngeal fat, which are associated with aging. Another factor that could explain these findings might be a decreased partial arterial pressure of oxygen (PaO2) due to age-related changes in the respiratory system.
