Modern coding theory is based on the foundation of the sparse codes on graphs, such as the low-density parity-check (LDPC) codes, and the turbo-like codes (TCs) with component convolutional codes. The success of the LDPC codes and the TCs lies in their ability to perform low-complexity iterative message passing decoding procedures. The iterative message passing decoders that exchange messages prob
Retrospective studies suggest increased postoperative morbidity among alcohol misusers. We have prospectively studied the risk associated with alcohol intake among patients undergoing surgery. We investigated 15 persons who required colorectal surgery and who were drinking at least five Danish drinks per day. These patients were matched for sex, nutrition, age, weight, cardio-pulmonary disease, di
The aim of the study was to investigate to which degree and how fast cellular immunodepression may be reversed after cessation of alcohol intake. Delayed hypersensitivity was investigated in ten severe alcoholics and in seven moderate consumers. A group of eight previous drinkers was tested for comparison. The skin test responses were modest initially with a median area of response of 12 mm2 in th
Data on the association between alcohol abuse and cancer morbidity are scarce in large cohorts of non-hospitalised alcoholic men and women. Of 18, 368 alcohol abusers who entered an outpatient clinic in Copenhagen during 1954-87, 18, 307 were followed and their cancer incidence was compared with that of the total Danish population. On average the 15, 214 men were observed for 12.9 years and the 3,
Alcohol abusers have suppressed cellular immune function. The aim of the study was to investigate the time of sobriety required to normalize immune function. Delayed hypersensitivity was investigated during disulfiram controlled abstinence in ten heavy alcoholics and in seven moderate drinkers without liver diseases. For comparison a control group of eight previous drinkers was tested. The skin te
Chemotherapy resistance and relapses are common in high-risk neuroblastoma (NB). Here, we developed a clinically relevant in vivo treatment protocol mimicking the first-line five-chemotherapy treatment regimen of high-risk NB and applied this protocol to mice with MYCN-amplified NB patient-derived xenografts (PDXs). Genomic and transcriptomic analyses were used to reveal NB chemoresistance mechan
The postoperative course and final outcome after evacuation of subdural haematoma are described in 106 male patients in relation to their alcohol consumption. One-third of the patients were alcohol abusers, drinking at least 60 g of ethanol daily. Despite comparable head trauma, they had a significantly higher incidence of acute subdural haematomas and showed increased postoperative morbidity and
Postoperative morbidity after hysterectomy was prospectively studied in 229 consecutive patients in our departments. The incidence of alcohol abuse (>60 gm of alcohol daily) and social drinking (between 25 and 60 gm of alcohol daily) was 6.5% for each. When compared with the social drinkers and the control group, the alcohol abuse group had significantly more complications (80% vs 27% and 80% vs 1
The postoperative morbidity after osteosynthesis of malleolar fractures was investigated retrospectively by comparing 90 alcohol abusers with 90 controls. The two groups were selected from 626 male patients and were matched regarding trauma, treatment for cardiovascular, pulmonary and endocrine diseases, age, weight, smoking habits, anaesthesia and duration of surgery. The alcohol abusers develope
The bone marrow microenvironment provides indispensable factors to sustain blood production throughout life. It is also a hotspot for the progression of hematologic disorders and the most frequent site of solid tumor metastasis. Preclinical research relies on xenograft mouse models, but these models preclude the human-specific functional interactions of stem cells with their bone marrow microenvir
Sixteen patients were treated for gastrocolic fistula arising as a complication of peptic ulcer (11 cases), colonic perforation (2), gastric cancer (1), colonic cancer (1) or pancreatitis (1). The predominant symptoms were diarrhoea, weight loss and abdominal pain. Barium meal and barium enema were the most reliable means of diagnosis, and no fistula was gastroscopically demonstrable. A one-stage
A retrospective study is presented of 297 patients operated upon for perforated benign gastric ulcer in Denmark from 1975 to 1984. Male: female ratio was 0.9:1, mean age 64.2 years. The numbers of gastric and prepyloric perforations were almost equal (156:141), but gastric perforations were more frequent in elderly women and prepyloric perforations in younger men. Simple closure was performed in 8
Morbidity after transurethral resection of the prostate gland was retrospectively investigated by comparing 73 alcoholics with 73 controls (daily alcohol consumption ≥60 g vs. <25 g). The compared groups derived from 1172 patients and were matched for diagnosis, age, weight, smoking habits, treatment for cardiovascular, pulmonary or endocrine diseases, anaesthesia and weight of resected tissue. Th
Of 1, 400 consecutive patients applying to an outpatient clinic for treatment of alcoholism, 477 complained of upper abdominal dyspepsia. After 2 weeks of abstinence, 78 had persisting complaints; of these, 72% had oesophagitis at endoscopy. The 53 patients with oesophagitis as the sole diagnosis were randomized to treatment with either ranitidine or a combination of alginate/antacid chewing table
Postoperative morbidity after colorectal surgery was retrospectively investigated, comparing 32 alcoholics (≥60 gm of alcohol a day) to 32 controls (<25 gm of alcohol a day). The material originated from 260 male patients and the two groups were paired with respect to operative procedure, diagnosis, age-complicating cardiopulmonary diseases, weight, and smoking habits. Postoperative morbidity was
ABSTRACT. Erythrocyte mean cell volume (MCV) correlates well to alcohol intake in moderate alcoholism, but only about 50% of heavy drinkers have increased MCV. To evaluate the influence of the duration and extent of a drinking episode on MCV, 64 addictive alcoholics were investigated prospectively within two weeks after a drinking period. Their daily alcohol intake was 120–480 g and the actual dri
