Predictive analysis of severe hypocalcemia following total parathyroidectomy for renal secondary hyperparathyroidism.

OBJECTIVE: This study aimed to evaluate the incidence and identify risk factors for severe hypocalcemia following total parathyroidectomy (TPTX) in patients with renal secondary hyperparathyroidism (SHPT). PATIENTS AND METHODS: We included patients undergoing maintenance hemodialysis or peritoneal dialysis who underwent TPTX from January 1, 2018, to April 30, 2023. Participants were categorized into groups based on postoperative corrected serum calcium levels: severe hypocalcemia (<1.8 mmol/L) and non-severe hypocalcemia (≥1.8 mmol/L). We conducted univariate analyses of demographic and laboratory data to identify potential risk factors, which were further analyzed using a binary logistic regression model. RESULTS: Significant associations were observed with age, dialysis duration exceeding five years, type of dialysis (peritoneal dialysis), lower preoperative corrected serum calcium, elevated preoperative intact parathyroid hormone (iPTH), and increased preoperative alkaline phosphatase (ALP) levels (all p<0.05). Age, preoperative iPTH, and ALP levels were identified as independent risk factors for severe hypocalcemia post-TPTX. CONCLUSIONS: Younger patients with renal SHPT who have elevated preoperative iPTH and ALP levels are at an increased risk of experiencing severe hypocalcemia following TPTX. These findings underscore the importance of careful preoperative assessment and monitoring to mitigate the risk of this complication.

Randomized controlled trials of serotonin-norepinephrine reuptake inhibitor in treating major depressive disorder in children and adolescents: a meta-analysis of efficacy and acceptability

New generation antidepressant therapies, including serotonin-norepinephrine reuptake inhibitor (SNRIs), were introduced in the late 1980s; however, few comprehensive studies have compared the benefits and risks of various contemporary treatments for major depressive disorder (MDD) in young patients. A comprehensive literature search of PubMed, Cochrane, Embase, Web of Science, and PsycINFO databases was conducted from 1970 to January 2015. Only clinical trials that randomly assigned one SNRI or placebo to patients aged 7 to 18 years who met the diagnostic criteria for major depressive disorder were included. Treatment success, dropout rate, and suicidal ideation/attempt outcomes were measured. Primary efficacy was determined by pooling the risk ratios (RRs) of treatment response and remission. Acceptability was determined by pooling the RRs of dropouts for all reasons and for adverse effects as well as suicide-risk outcomes. Five trials with a total of 973 patients were included. SNRIs were not significantly more effective than placebo for treatment response but were for remission. The comparison of patients taking SNRIs that dropped out for all reasons and those taking placebo did not reach statistical significance. Significantly more patients taking SNRIs dropped out for adverse effects than those taking placebo. No significant difference was found in suicide-related risk outcomes. SNRI therapy does not display a superior efficacy and is not better tolerated compared to placebo in these young patients. However, duloxetine has a potential beneficial effect for depression in young populations, showing a need for further research.
