Purpose: Chronic fatigue (CF) affects 25–30% of lymphoma survivors, but interventions designed to reduce fatigue are lacking. The main aim of this study was to test the feasibility of a multidimensional intervention study in lymphoma survivors with CF. Secondary aims were to describe individual changes in fatigue, quality of life (QoL) and physical performance from pre (T0) to post (T1) intervention. Methods: This feasibility study was as a one-armed intervention study performed in 2021. Hodgkin or aggressive non-Hodgkin lymphoma survivors received mailed study information and Chalder Fatigue Questionnaire and were asked to respond if they suffered from fatigue. The 12-week intervention included patient education, physical exercise, a cognitive behavioural therapy (CBT)-based group program and nutritional counselling. Feasibility data included patient recruitment, completion of assessments, adherence to the intervention and patient-reported experience measures. Participants responded to questionnaires and underwent physical tests at T0 and T1. Results: Seven lymphoma survivors with CF were included. Of all assessments, 91% and 83% were completed at T0 and T1, respectively. Adherence to the interventional components varied from 69% to 91%. At T1, all participants rated exercise as useful, of whom five rated the CBT-based program and five rated individual nutritional counselling as useful. Five participants reported improved fatigue, QoL and physical performance. Conclusion: Lymphoma survivors with CF participating in a multidimensional intervention designed to reduce the level of fatigue showed high assessment completion rate and intervention adherence rate. Most of the participants evaluated the program as useful and improved their level of fatigue, QoL and physical performance after the intervention.

Objectives: The aims of this study were to quantify salivary concentrations of bisphenol A (BPA) and to assess if presence of dental composite fillings is associated with higher BPA levels in saliva. Materials and methods: Twenty individuals with six or more tooth surfaces filled with polymer-based dental materials (composite group) and 20 individuals without any polymer-based materials (control group) were included in the study. Saliva was collected in polypropylene tubes and stored at −80 °C before analysis. Concentration of free (unconjugated) and total bisphenol A was determined by liquid chromatography/mass spectrometry (LC/MS). Values below limit of detection (0.1 ng/mL) were set to one-half of the limit of detection. Mann-Whitney U test (one sided; the Exact Tests Option in IBM-SPSS version 21) was used for the statistical analyses. Results: The concentration of BPA in saliva was very low. In the composite group, 8 of 20 samples had detectable concentrations of BPA. In the control group, 3 of 20 samples had detectable concentrations of BPA. Statistical analysis indicated that the concentration of unconjugated BPA was slightly higher in the composite group ( p = 0.044) than in the control group. Conclusions: Presence of dental composites may be associated with slightly higher concentration of unconjugated BPA in saliva. However, additional studies using sensitive analytical methods are needed before firm conclusions can be drawn. Influence from other factors, like food intake and time of the day for saliva sampling, must be considered. Clinical relevance: The relative contribution of existing polymer-based dental fillings to total BPA exposure seems to be low. [ABSTRACT FROM AUTHOR]

Genome-wide association studies have revealed that the 16p13 chromosomal region, including CLEC16A, DEXI, CIITA and SOCS1, is associated with susceptibility to autoimmune diseases. As non-coding single-nucleotide polymorphisms (SNPs) may confer susceptibility to disease by affecting expression of nearby genes, we examined whether autoimmune-associated intronic CLEC16A SNPs (rs12708716, rs6498169 and rs7206912) correlate with the expression of CLEC16A itself as well as neighboring genes in whole-blood and thymic samples. Real-time quantitative PCR analyses show that SOCS1 and DEXI expression was lower in thymic samples carrying at least one of the CLEC16A risk alleles compared with non-carriers of the risk allele. Linear regression analysis revealed a significant correlation between the expression level of CLEC16A and that of SOCS1 and DEXI in thymic samples. These data indicate a possible regulatory role for multiple sclerosis-associated non-coding CLEC16A SNPs and a common control mechanism for the expression of CLEC16A, SOCS1 and DEXI.

Objective: To evaluate the cure rate of Helicobacter pylori infection, including the impact of in vitro metronidazole resistance (M-R), and the side effects of a simplified 10-day bismuth triple therapy in routine clinical practice. Methods: From September 1995 to March 1996,248 consecutive H. pylori-positive patients received 10 days of bismuth subnitrate 150 mg, oxytetracycline 500 mg, and metronidazole 400 mg, all t.i.d. Before treatment, upper endoscopy, including biopsy specimens for microbiological analysis and IgG serology were performed. M-R was found in 45% of females and 36% of males. At least 2 months after treatment, H. pylori status was assessed by the 14C urea breath test (n = 131), endoscopy (n = 37), urea breath test and endoscopy (n = 63), or solely by IgG serology (n = 7). Ten patients withdrew. IgG serology was performed again after 1 yr. Results: H. pylori infection was cured in 205 patients: 86% by all-patients-treated analysis and 83% by intention-to-treat analysis. When patients were classified according to pretreatment metronidazole susceptibility, cure of infection was achieved in 76% of females harboring M-R strains versus 96% of those with sensitive strains (p = 0.002) and in 81% versus 88% (p = 0.34) of males with M-R versus sensitive strains, respectively. Twelve patients (5%) had to stop treatment prematurely because of severe side effects, but eight of them were treated successfully. One case of H. pylori infection (0.6%) was detected at 1-yr follow-up. Conclusions: Ten-day bismuth triple therapy t.i.d. was effective in curing H. pylori infection in the context of routine clinical practice. The efficacy was reduced in females harboring M-R strains.

Objectives: To compare the efficacy and side effects of standard bismuth triple therapy with those of omeprazole-based triple therapy in patients with Helicobacter pylori infection and duodenal ulcer disease. Methods: One hundred patients were prospectively recruited and randomized to receive either bismuth subnitrate 75 mg q.i.d., oxytetracycline 500 mg q.i.d., and metronidazole 400 mg b.i.d. (regimen BTM), or omeprazole 20 mg b.i.d., amoxicillin 750 mg b.i.d., and metronidazole 400 mg b.i.d. (regimen OAM), both for 14 days. Upper endoscopy (with antral biopsy specimens for microbiology and antral and corpus biopsy specimens for histology) was performed before treatment, after 2 months, and again 1 yr after treatment. Serum samples for serology (IgG) were taken. Patients with in vitro metronidazole-resistant (M-R) H. pylori strains were excluded. In a nonrandomized study, 41 patients with M-R strains were given either BTM or OAM. Results: According to intention-to-treat analysis, H. pylori cure rates were 91% and 96% with BTM and OAM, respectively (p = 0.45). In the BTM group, the mean total side effect score was higher (p < 0.001), and more severe side effects were reported (32% vs. 4%, p < 0.001). In the nonrandomized group of patients with M-R strains, H. pylori cure rates were 88% and 67% with BTM and OAM, respectively. All of the successfully treated patients were still H. pylori-negative after 1 yr. Conclusions: Both treatment regimens were highly effective in curing H. pylori infection in patients with metronidazole-sensitive strains. Omeprazole-based triple therapy was tolerated better than standard bismuth-based triple therapy. [ABSTRACT FROM AUTHOR]

Objectives: To compare cure rates of Helicobacter pylori (H. pylori) infection, ulcer healing, and side effects of three simplified regimens of triple therapy in patients with peptic ulcer disease. Methods: Two hundred thirty-one patients were prospectively randomized to receive either regimen OAM (omeprazole 20 mg b.i.d., amoxicillin 750 mg b.i.d., and metronidazole 400 g b.i.d.), OCM (omeprazole 20 mg b.i.d., clarithromycin 250 mg b.i.d., and metronidazole 400 mg b.i.d.), or BCM (bismuth subcitrate 240 mg b.i.d., claritbromycin 250 mg b.i.d., and metronidazole 400 mg b.i.d.), all for 10 days. Side effects were reported immediately afterward in a self-administered questionnaire. Upper endoscopy was carried out before treatment and 2 months after treatment. Three antral and three corpus biopsy specimens were analyzed microbiologically and with rapid urease test to determine the presence of H. pylori. Altogether 143 patients (62%) had an active ulcer at start of treatment. Metronidazole resistant (M-R) H. pylori strains were found in 30% of patients, while none had clarithromycin resistant (C-R) strains. Results: According to intention-to-treat analysis, H. pylori cure rates were 91, 95, and 95% with OAM, OCM, and BCM, respectively (p = 0.63). In patients with metronidazole-sensitive (M-S) strains versus M-R strains, the cure rates were 96 versus 77% with OAM (p = 0.025), 94 versus 94% with OCM, and 94 versus 96% with BCM. Ulcer healing rates were 95, 94, and 92%, respectively (p = 0.91). There were no significant differences in side effects between the regimens, and only five patients (2%) had to stop the treatment prematurely. Conclusions: All treatment regimens were highly effective for cure of H. pylori infection and for ulcer healing. Metronidazole resistance reduced the efficacy of OAM, but was of no importance for the efficacy of OCM or BCM. Side effects were of minor importance. [ABSTRACT FROM AUTHOR]
