Treatment of acute variceal bleeding

The management of variceal bleeding remains a clinical challenge with a high mortality. Standardisation in supportive and new therapeutic treatments seems to have improved survival within the last 25 years. Although overall survival has improved in recent years, mortality is still closely related to failure to control initial bleeding or early re-bleeding occurring in up to 30-40% of patients. Initial procedures are to secure and protect the airway, and administer volume replacement to stabilize the patient. Treatment with vasoactive drugs should be started as soon as possible, since a reduction in portal pressure is associated with a better control of bleeding and may facilitate later endoscopic procedures. Vasopressin and its analogues Terlipressin and somatostatin and analogues are the two types of medicine, which has been evaluated. In meta-analysis, only Terlipressin have demonstrated effects on control of bleeding and on mortality. Somatostatin and its analogues improve control of bleeding, but show in meta-analysis no effects on mortality. Approximately 20% of patients with variceal bleeding will suffer from an infection, when they are hospitalized. Invasive procedures will further increase the risk of bacterial infections. Meta-analysis of clinical trials comparing antibiotics with placebo demonstrates that antibiotic prophylaxis improves survival with 9% (p<0.004). Quinolones or intravenous cephalosporins should be preferred. Early endoscopy should be performed in patients with major bleeding. Endoscopic therapy increases control of bleeding and decreases the risks of rebleeding and mortality. Ligation is probably more effective than sclerotherapy with fewer complications and should therefore be preferred, if possible. In case of gastric variceal bleeding, tissue adhesives should be used. In conclusion: Improvements in resuscitation and prevention of complications have together with introduction of vasoactive drugs and refinement of endoscopic therapy majorily changed the prognosis of the patient presenting with variceal bleeding.     

Psychoeducational intervention for patients with cutaneous malignant melanoma: a replication study.

PURPOSE: In 1993, a randomized intervention study among patients with malignant melanoma showed a significant decrease in psychological distress and increased coping capacity 6 months after the intervention and enhanced survival 6 years later. We applied a similar intervention with a few modifications in a randomized controlled trial among Danish patients with malignant melanoma and evaluated results on immediate and long-term effects on psychological distress and coping capacity. PATIENTS AND METHODS: A total of 262 patients with primary cutaneous malignant melanoma were randomly assigned to the control or intervention group. Patients in the intervention group were offered six weekly sessions of 2 hours of psychoeducation, consisting of health education, enhancement of problem-solving skills, stress management, and psychological support. The participants were assessed at baseline before random assignment and 6 and 12 months after surgery. The analyses of the main effects of the intervention were based on analyses of covariance. RESULTS: The patients in the intervention group showed significantly less fatigue, greater vigor, and lower total mood disturbance compared with the controls, and they used significantly more active-behavioral and active-cognitive coping than the patients in the control group. The improvements were only significant at first follow-up. CONCLUSION: The findings of this study support the results of an earlier intervention study among patients with malignant melanoma and indicate that a psychoeducational group intervention for such patients can decrease psychological distress and enhance effective coping. However, this effect is short term and the clinical relevance is not obvious.     

Ultrasound evidence of altered lumbar connective tissue structure in human subjects with chronic low back pain

Background  

Although the connective tissues forming the fascial planes of the back have been hypothesized to play a role in the pathogenesis of chronic low back pain (LBP), there have been no previous studies quantitatively evaluating connective tissue structure in this condition. The goal of this study was to perform an ultrasound-based comparison of perimuscular connective tissue structure in the lumbar region in a group of human subjects with chronic or recurrent LBP for more than 12 months, compared with a group of subjects without LBP.     

Counseling interventions delivered in women with breast cancer to improve health-related quality of life: a systematic review

Background

Higher survival rates for breast cancer patients have led to concerns in dealing with short- and long-term side effects. The most common complications are impairment of shoulder functions, pain, lymphedema, and dysesthesia of the injured arm; psychological consequences concern: emotional distress, anxiety, and depression, thereby, deeply impacting/affecting daily living activity, and health-related quality of life.

Objective

To perform a systematic review for assessing the efficacy or effectiveness of interventions aiming at improving health-related quality of life, return to daily activity, and correct lifestyles among breast cancer patients.

Methods

A literature search was conducted in December 2016 using the databases PubMed and Scopus. Search terms included: (counseling) AND (breast cancer) AND (quality of life). Articles on counseling interventions to improve quality of life, physical and psychological outcomes were included.

Results

Thirty-five articles met the inclusion criteria. The interventions were grouped in five main areas: concerning lifestyle counseling interventions, related to combined interventions (physical activity and nutritional counseling), physical therapy, peer counseling, multidisciplinary approach, included psychological, psycho-educational interventions, and cognitive-behavior therapy (CBT). Exercise counseling as well as physical therapy are effective to improve shoulder mobility, healing wounds, and limb strength. Psychological therapies such as psychoeducation and CBT may help to realize a social and psychological rehabilitation.

Conclusion

A multidisciplinary approach can help in sustaining and restoring impaired physical, psychosocial, and occupational outcomes of breast cancer patients.

     

Stress ulcer prophylaxis in adult intensive care unit patients – a protocol for a systematic review

Background

In the intensive care unit (ICU), stress ulcer prophylaxis with proton pump inhibitors or histamine‐2‐receptor antagonists is standard of care although gastrointestinal bleeding remains uncommon. It remains unknown whether its use is associated with benefits or harms and the quality of evidence supporting the use of stress ulcer prophylaxis has been questioned. Accordingly, the objective of this systematic review was to critically assess the evidence from randomized clinical trials on the benefits and harms of stress ulcer prophylaxis vs. placebo or no prophylaxis in adult ICU patients.

Methods

We will systematically search for randomized clinical trials in major international databases. Two authors will independently screen and select trials for inclusion, extract data and assess the methodological quality using the Cochrane risk of bias tool. Any disagreement will be resolved by consensus. We will perform conventional meta‐analyses using Review Manager, and STATA 15, and we will assess the risk of random errors using Trial Sequential Analysis. Also, we will assess and report the overall quality of evidence for all outcomes according to GRADE.

Discussion

The evidence on the benefits and harms of stress ulcer prophylaxis in adult ICU patients is unclear and an updated systematic review is warranted as new trials have been published. To control risks of systematic and random errors, we will use Cochrane and GRADE methodology and Trial Sequential Analysis. Our ambition with this systematic review is to provide updated, reliable and precise data to better inform decision makers on the use of stress ulcer prophylaxis in adult ICU patients.

     

Cytokine gene polymorphisms and sudden infant death syndrome

Aim: Several studies indicate that the mucosal immune system is stimulated in cases of sudden infant death syndrome (SIDS), and our hypothesis is that this immune reaction is because of an unfavourable combination of functional polymorphisms in the cytokine genes. Methods: Thus, in this study, single nucleotide polymorphisms (SNPs) in the genes encoding IL‐6, IL‐8, IL‐12, IL‐13, IL‐16, IL‐18 and IFNγ were investigated in 148 SIDS cases, 56 borderline SIDS cases, 41 cases of infectious death and 131 controls. Results: Regarding genotype distribution, no differences between the investigated groups were found. However, in the SIDS group, the genotypes IL‐8 ?251AA/AT and IL‐8 ?781CT/TT were significantly more frequent in the SIDS cases found dead in a prone sleeping position, compared with SIDS cases found dead in other sleeping positions. In addition, there was an association between fever prior to death and the genotype IL‐13 +4464GG in the cases of infectious death. Conclusion: This study indicates that specific interleukin genotypes are a part of a genetic make up that make infants sleeping prone at risk for SIDS.
