This study focuses on the 4th treatment step in Degeberga WWTP treatment plant, the first full scale GAC filter in Sweden installed in April 2020 for removal of micropollutants. The two GAC filters, containing two different carbon types, has operated flawlessly for three years (30,000 bed volumes) without requiring backwashing. The results indicate that the sand filter provides effective protection to the carbon filters, preventing solids from reaching the carbon and reducing the growth of organic matter.

Materials And Methods: This comparative cross-sectional study comprised patients with one of four groups of substance use disorders - alcohol, cannabis, central nervous system stimulants (CNSS), and opiates. All participants underwent a dental examination and were included in the study based on their clinical findings.
In this study, alcohol was administered intravenously to study whether its effects on mood should preferably be studied as a bi- or unipolar phenomenon. This was studied in a double-blind, placebo-balanced, design on six healthy male volunteers. Of the three bipolar aspects of mood (calmness, activity, and pleasantness), only calmness was significantly affected by intravenous alcohol.

The aim was: (i) to investigate the possible predictive factors for successful treatment termination, and (ii) the long-term outcome effects and life situation of MMT patients and those who terminated the treatment.
Methods: The patients were interviewed at the start and approximately 15 years later, and divided into four groups: (1) no withdrawal attempts, (2) forced to stop the treatment, (3) successful tapering and (4) non-successful tapering.
Background: Benzodiazepines (BZD) are the most widely used sedative-hypnotics, and evidence is rapidly accumulating suggesting potential BZD dependence, association of chronic use with adverse effects and a definite abstinence syndrome produced by withdrawal.
Aims: The present investigation followed prospectively long-term BZD users over 1 year following graded BZD withdrawal in terms of clinical and withdrawal symptoms.
Methods: Clinical symptoms were measured by the Comprehensive Psychopathological Rating Scale (CPRS) and by the Newcastle Anxiety and Depression Diagnostic Index (NADDI) in a sample of BZD users over a 50-week period following graded BZD withdrawal.
Objectives: To compare markers of alcohol consumption.
Design And Methods: Measurement of urinary ethyl glucuronide, 5-hydroxytryptophol, 5-hydroxytryptophol glucuronide, 5-hydroxyindole acetic acid in 10 patients during alcohol withdrawal.
Results: 5-Hydroxytryptophol glucuronide was measured by ELISA with good analytical precision, its diagnostic specificity and sensitivity was better than that of 5-hydroxytryptophol and its correlation was closer to ethyl glucuronide than to 5-hydroxytryptophol.
Objective: To evaluate the prevalence of alcoholism and benzodiazepine abuse among patients with obstructive sleep apnea syndrome (OSAS). Such abuse may aggravate the tendency to apneas, especially in patients with OSAS.
Material And Methods: The study included 98 consecutive OSAS patients.
