Proton-pump inhibitor use amongst patients with severe hypomagnesemia.

Introduction: Long-term proton pump inhibitor (PPI) use has been associated with hypomagnesemia. It is unknown how frequently PPI use is implicated in patients with severe hypomagnesemia, and its clinical course or risk factors. Methods: All patients with severe hypomagnesemia from 2013 to 2016 in a tertiary center were assessed for likelihood of PPI-related hypomagnesemia using Naranjo algorithm, and we described the clinical course. The clinical characteristics of each case of PPI-related severe hypomagnesemia was compared with three controls on long-term PPI without hypomagnesemia, to assess for risk factors of developing severe hypomagnesemia. Results: Amongst 53,149 patients with serum magnesium measurements, 360 patients had severe hypomagnesemia (<0.4 mmol/L). 189 of 360 (52.5%) patients had at least possible PPI-related hypomagnesemia (128 possible, 59 probable, two definite). 49 of 189 (24.7%) patients had no other etiology for hypomagnesemia. PPI was stopped in 43 (22.8%) patients. Seventy (37.0%) patients had no indication for long-term PPI use. Hypomagnesemia resolved in most patients after supplementation, but recurrence was higher in patients who continued PPI, 69.7% versus 35.7%, p = 0.009. On multivariate analysis, risk factors for hypomagnesemia were female gender (OR 1.73; 95% CI: 1.17-2.57), diabetes mellitus (OR, 4.62; 95% CI: 3.05-7.00), low BMI (OR, 0.90; 95% CI: 0.86-0.94), high-dose PPI (OR, 1.96; 95% CI: 1.29-2.98), renal impairment (OR, 3.85; 95% CI: 2.58-5.75), and diuretic use (OR, 1.68; 95% CI: 1.09-2.61). Conclusion: In patients with severe hypomagnesemia, clinicians should consider the possibility of PPI-related hypomagnesemia and re-examine the indication for continued PPI use, or consider a lower dose.

Results of modified CO2 laser-assisted sclerectomy monotherapy versus trabeculectomy combination therapy in the eyes with uveitic glaucoma.

This study compared the efficacy of modified CO2 laser-assisted sclerectomy surgery (CLASS) with combined CLASS and trabeculectomy (CLASS-TRAB) in patients with uveitic glaucoma (UG). UG patients who underwent CLASS-TRAB between August 2015 and April 2019 were retrospectively compared with a control group who underwent a modified CLASS standalone procedure during the same period. Visual acuity, intraocular pressure (IOP), use of supplemental medical therapy and postoperative complications were recorded at baseline, 1 week, 3 months, 6 months and 12 months. Forty patients (40 eyes) were enrolled, and each group had 20 patients (20 eyes). The age and sex distribution were matched between groups (P > 0.05). Both the preoperative IOP (CLASS: 34.9 ± 9.3 mmHg, CLASS-TRAB: 36.8 ± 8.7 mmHg; P > 0.05) and number of glaucoma medications (CLASS: 3.3 ± 0.4, CLASS-TRAB: 3.5 ± 0.5; P > 0.05) were relatively higher in the CLASS-TRAB group than in the CLASS group. At the final follow-up, the IOP (CLASS: 12.9 ± 3.4 mmHg, CLASS-TRAB: 11.2 ± 2.5 mmHg) and number of glaucoma medications (CLASS: 0.4 ± 0.7 and CLASS-TRAB: 0.2 ± 0.5) significantly decreased in both groups (P < 0.01). Both the complete success rate and qualified success rate were comparable between the two groups (CLASS versus CLASS-TRAB: 55% versus 80%, P = 0.09; 80% versus 95%, P = 0.34). CLASS-TRAB is as efficient as modified CLASS in terms of the IOP-lowering effect, providing a new option for patients with UG that is severe and ineligible for other treatments.

Factors Associated with Behaviors Toward End-of-life Care Among Chinese Oncology Nurses: A Cross-Sectional Study.

PURPOSE: The goal of this study was to describe the current status of oncology nurses' behaviors toward end of life (EOL) care in China and to explore the factors associated with oncology nurses' behaviors toward EOL care. METHODS: A cross-sectional design was applied and a convenience sample of 1038 oncology nurses from 22 grade A hospitals were recruited into this study. A general social demographic data questionnaire was administered, and the Chinese version of Nurses' Behaviors of Caring for Dying Patients Scale was used to assess nurse behavior toward EOL care. The total score ranges from 40 to 200 points. Data were analyzed with SPSS 26.0 software. RESULTS: Chinese oncology nurses' average score of holistic EOL care behaviors was 2.97 ± 0.59. Oncology nurses provide physical care most (3.81 ± 0.76), followed by family care (3.02 ± 0.86), and spiritual care (2.37 ± 0.67). Multiple regression analysis showed that a higher frequency of sharing EOL care experience with colleagues, in-service palliative care education, higher level of head nurse support for EOL patient care, more cases of EOL care, higher working position, and nurse's perceived high level of support were positively associated with behavior toward EOL care. These six factors explained 16.2% of the total variance. CONCLUSIONS: The results may help provide a basis for converting behavior for EOL care among oncology nurses and design interventions to better improve quality of life for EOL patients with cancer in China.

Higher 25-hydroxyvitamin D level is associated with increased risk for Behçet's disease.

BACKGROUND & AIM: Previous studies showed a vitamin D deficiency in patients with Behçet's disease, suggesting potential benefits of vitamin D supplementation in the prevention and treatment of Behçet's disease. Interpretation of these studies may be limited by reverse causality or confounding bias. We aim to determine the causal association between serum 25-hydroxyvitamin D [25(OH)D] and the risk of Behçet's disease by Mendelian randomization. METHODS: An allele score formed by four variants (rs2282679, rs10741657, rs12785878 and rs6013897) that were associated with serum 25(OH)D level, was examined using data of genome-wide association study (GWAS) on 999 Behçet's disease and 4417 healthy individuals of Chinese ancestry and validated using data of GWAS on 1215 Behçet's disease and 1278 controls of Turkish ancestry. The primary outcome was the risk of Behçet's disease, evaluated by an inverse variance weighted average of the associations with genetically determined 25(OH)D levels. RESULTS: The inverse variance weighted estimate showed that genetically increased 25(OH)D level was associated with a higher risk of Behçet's disease. In the Chinese cohort, the odds ratio for Behçet's disease in one standard deviation increase of natural log-transformed 25(OH)D level was 3.82 (95% CI: 1.27-11.42). Data from Turkish cohort confirmed the association with Behçet's disease (OR, 95% CI: 4.18, 1.15-15.12). In overall combination of Chinese and Turkish cohorts, the odds ratio for Behçet's disease per standard deviation increase of natural log-transformed 25(OH)D level was estimated to be 3.96 (95% CI: 1.72-9.13; P = 0.001). No significant evidence of pleiotropy and heterogeneity was detected. CONCLUSIONS: On the basis of evidence in 7909 human beings, this study provides the newest indication that a lifelong higher 25(OH)D level is associated with an increased risk of Behçet's disease. Special attention should be paid to the potential harm of long-term or high-dose use of vitamin D supplements in clinical practice.

Effectiveness of Mindfulness-based Therapy for Reducing Anxiety and Depression in Patients With Cancer: A Meta-analysis.

Anxiety and depression are common among patients with cancer, and are often treated with psychological interventions including mindfulness-based therapy.The aim of the study was to perform a meta-analysis of the effectiveness of mindfulness-based interventions for improving anxiety and depression in patients with cancer.Medline, the Cochrane Library, EMBASE, and Google Scholar were searched. The randomized controlled trials designed for patients diagnosed with cancer were included. Mindfulness-based interventions were provided.The outcomes assessed were the changes in anxiety and depression scores from before to after the intervention. The treatment response was determined by calculating the standardized mean difference (SMD) for individual studies and for pooled study results. Subgroup analyses by cancer type, type of therapy, and length of follow-up were performed.Seven studies, involving 469 participants who received mindfulness-based interventions and 419 participants in a control group, were included in the meta-analysis. Mindfulness-based stress reduction and art therapy were the most common interventions (5/7 studies). All studies reported anxiety and depression scores. The pooled SMD of the change in anxiety significantly favored mindfulness-based therapy over control treatment (-0.75, 95% confidence interval -1.28, -0.22, P = 0.005). Likewise, the pooled SMD of the change in depression also significantly favored mindfulness-based therapy over control (-0.90, 95% confidence interval -1.53, -0.26, P = 0.006). During the length of follow-ups less than 12 weeks, mindfulness-based therapy significantly improved anxiety for follow-up ≤12 weeks after the start of therapy, but not >12 weeks after the start of therapy.There was a lack of consistency between the studies in the type of mindfulness-based/control intervention implemented. Patients had different forms of cancer. Subgroup analyses included a relatively small number of studies and did not account for factors such as the severity of anxiety and/or depression, the time since diagnosis, and cancer stage.Mindfulness-based interventions effectively relieved anxiety and depression among patients with cancer. However, additional research is still warranted to determine how long the beneficial effects of mindfulness-based therapy persist.
