Cognitive behavioral therapy for insomnia to treat major depressive disorder with comorbid insomnia: A systematic review and meta-analysis.

OBJECTIVE: Cognitive behavioral therapy for insomnia (CBT-I) has demonstrated efficacy for both insomnia and depression. With a tenfold increase in expected participant numbers, we aimed to update the systematic review and meta-analysis of CBT-I for major depressive disorders (MDD). METHODS: Multiple databases were searched up to March 27th 2024 to include all randomized controlled trials examining CBT-I among adults with MDD. The certainty of evidence was evaluated using GRADE. The primary outcome was depression response at post-treatment. Secondary outcomes included insomnia remission and all-cause dropout at post-treatment. Frequentist random-effects pairwise meta-analyses were performed using odds ratio (OR) for dichotomous outcomes. This study was prospectively registered (https://osf.io/kcndz/). RESULTS: Nineteen trials with 4808 randomized participants were identified (mean age, 33.2 [standardized deviation 15.0] years, 73.2 % women. Mean Insomnia Severity Index 19.2 [5.4], median Patient Health Questionnaire-9 16 [range, 8-21]). CBT-I was more beneficial than control conditions for depression response (OR 2.28 [95 % Confidence Interval (CI), 1.67-3.12; GRADE certainty of evidence: moderate), insomnia remission (OR 3.57 [95%CI, 2.48-5.14]: moderate) but could lead to more dropout (OR 1.69 [95%CI, 0.98-2.89]: low). Depression improvement was seen beyond the sleep domain. With a control condition depression response rate of 17 % at post-treatment (median 8 weeks), CBT-I yielded a 32 % response rate (95 % CI, 26 %-39 %). CONCLUSIONS: This meta-analysis indicates that CBT-I has significant effects on depressive symptoms beyond the sleep domain among people with MDD. Despite higher dropout rates, these findings suggest CBT-I is an effective treatment for depression comorbid with insomnia.

Differences in Prognosis and Recurrence Patterns Between Ulcerative Colitis-Associated Colorectal Cancer and Sporadic Colorectal Cancer: A Matched-Pair Analysis.

BACKGROUND: Clinicopathological differences exist between ulcerative colitis-associated colorectal cancer (UC-CRC) and sporadic colorectal cancer (S-CRC). However, differences in the prognosis remain controversial, and the reason for these differences remains unclear. We therefore assessed the differences between patients with UC-CRC and S-CRC. PATIENTS AND METHODS: This was a matched-pair analysis of the clinicopathological characteristics and prognosis of patients with UC-CRC and S-CRC who underwent colorectal resection between January 2000 and December 2021 at two institutions. Patients were matched according to age, sex, date of surgery, tumor location, and Union for International Cancer Control (UICC) stage. RESULTS: A total of 5992 patients underwent surgery for CRC at the two institutions, and 288 patients (48 with UC-CRC and 240 with S-CRC) were matched in this study. Patients with UC-CRC underwent more invasive surgery and had a longer operative time than those with S-CRC, but there was no marked difference in postoperative complications or perioperative mortality. Long-term outcomes showed a similar 5-year overall survival (OS) for UC-CRC and S-CRC (86.5% versus 88.8%, p = 0.742); however, in stage 3 patients, patients with UC-CRC had a poorer 5-year OS than those with S-CRC (51.4% versus 83.8%, p = 0.032). The first recurrence sites in stage 3 UC-CRC were peritoneal dissemination followed by the bones, while those in S-CRC were the liver and pulmonary system. CONCLUSIONS: Despite no significant differences in surgical outcomes, patients with UC-CRC had a poorer prognosis than those with S-CRC at stage 3. The recurrence patterns in UC-CRC differed from those in S-CRC, suggesting a possible prognostic difference.

Do measures of gain asymmetry and catch-up saccades improve video head impulse test agreement with caloric results?

Objective: To investigate the relative sensitivity and agreement of caloric testing and video head impulse test (vHIT) across four groups of vestibular disorders. Methods: Caloric and vHIT results of 118 patients with either Ménière's disease, vestibular neuritis/labyrinthitis, vestibular migraine, or vestibular schwannoma were retrospectively analyzed. vHIT gain, gain asymmetry, and catch-up-saccades (≥100°/sec) were compared with reference limits of 91 controls. Results: Abnormal caloric results and vHIT gain were recorded in 57.6 % and 33.1 % of patients, respectively. Consideration of all three measures increased vHIT sensitivity to 43.2 %, and concordance with caloric results improved from 66.1 % to 70.3 %. A significant interaction effect confirmed the relationship between tests depended on the diagnosis (p = 0.013). Vestibular migraine and vestibular neuritis/labyrinthitis produced similar results on both tests, usually normal and abnormal respectively. Vestibular schwannoma produced more caloric abnormalities than vHIT gain but not compared with catch-up-saccades and gain asymmetry; Ménière's disease produced more caloric abnormalities than all vHIT measures. When vHIT was normal (all measures), a 37 % canal paresis was 90 % specific for Ménière's disease. Conclusions: Rates of vHIT catch-up-saccades and gain asymmetry can improve sensitivity and concordance with caloric testing, but this is disease-dependent. Significance: vHIT outcome measures are complementary to the caloric test and each other.

Long-term Outcome After Repair of Transposition of the Great Arteries With Aortic Arch Obstruction.

BACKGROUND: This study compares the long-term outcomes of patients after repair of transposition of the great arteries (TGA) with and without aortic arch obstruction (AAO). METHODS: This is a single-institution, retrospective study between October 2004 and February 2023. Patients who underwent arterial switch operation and aortic arch repair (ASO-AAR group) with patch augmentation were compared with those without AAO (ASO group). The primary end point was survival; freedom from reintervention was a secondary end point. RESULTS: We identified 176 patients, 31 in the ASO-AAR group and 145 in the ASO group. The median follow-up period was 10.3 years. There were no differences between the ASO-AAR group and the ASO group in early deaths (3.2% vs 0.7%) and late deaths (3.2% vs 2.8%), or 15-year survival rates (92.6% vs 96.2%). Surgical and catheter-based reinterventions were higher in the ASO-AAR group, involving the pulmonary arteries (41.9% vs 4.8%, P < .001), aortic arch (16.1% vs 0.7%, P < .001), and residual ventricular septal defects (11.4% vs 0%, P = .05). The ASO-AAR group showed a higher prevalence of double-outlet right ventricle TGA-type (61.3% vs 4.1%, P < .001) and a lower aortopulmonary index (0.67 vs 1.01, P < .001). CONCLUSIONS: Patients undergoing surgical repair of TGA and AAO achieved excellent survival rates, comparable to patients with simple transposition. A higher rate of surgical and catheter-based reinterventions was observed in patients with arch obstruction and/or a low aortopulmonary index. AAR with patch augmentation proved to be an effective surgical technique with a low incidence of aortic reinterventions.

Establishing Optimal Control Cohorts for Phase 1 Trials: Retrospective Analysis of Clinical and Biological Outcomes in Neonates and Infants Undergoing Two-Ventricle Repair.

Phase 1 trials are primarily conducted to evaluate the safety and feasibility of new interventions, usually without recruiting control patients. This retrospective study aims to characterize clinical and biological outcomes in historical and contemporary cases of neonates and infants undergoing two-ventricle repair to facilitate future secondary endpoint analyses for such trials. This retrospective study included neonates/infants (ages ≤ 6 months) who underwent two-ventricle repair between 2015 and 2021 using the same criteria as our phase 1 trial (n = 199). Patients were allocated into the ventricular septal defect (n = 61), the Tetralogy of Fallot (TOF, n = 88), and the transposition of the great arteries (n = 50) groups with an additional comparison between two eras (2015-2019 vs. 2020-2021). Patient characteristics and most variables assessed were different between the three diagnostic groups indicating the importance of diagnostic matching for secondary analyses. Although the era did not alter cerebral/somatic oxygenation, ventricular function, neuroimaging findings, and complication rates, we observed improvement of inotropic and/or vasoactive-inotropic scores in all groups during the more recent era. In 2020-2021, the age and the body weight at the operation were higher, and hospital stay was shorter in the TOF group, suggesting the possible impact of the pandemic. Results also indicated that matching altered characteristics such as age at operation that may limit the temporal effects and optimize secondary analyses. Using optimal contemporary cases and historical data based on this study will assist in developing a comprehensive study design for a future efficacy/effectiveness trial.

Exploring the Molecular-Scale Structures at Solid/Liquid Interfaces of Li-Ion Battery Materials: A Force Spectroscopy Analysis with Sparse Modeling.

In this study, we clarify the liquid structure formed at the interface between LiCoO2 (LCO), the cathode material of Li-ion batteries, and propylene carbonate (PC), which is used as a solvent in the electrolyte, on a molecular scale. We apply sparse modeling-based modal analysis to force spectroscopy data measured by frequency modulation atomic force microscopy (FM-AFM) and show that each component in the FM-AFM force curve, such as oscillatory solvation force, background, and noise, can be automatically decomposed. Moreover, by combining detailed force curve analysis with solid/liquid interface simulations based on first-principles calculation, we have identified that there are distinct damped vibrational modes in the force curves at the LCO/PC interface with a period of about 0.57 nm and those with shorter periods, which likely correspond to the solvation forces associated with bulk-state PC molecules and those with PC molecules in "lying down" orientations.

Supramolecular Chirality Achieved by Assembly of Small π-Molecules of Octahydrobinaphtols with Axial Chirality.

5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthol (hbNaph) is an axially chiral molecule consisting of a smaller π-electronic system than that for 1,1'-bi-2-naphthol (BINOL). The absorption and circular dichroism (CD) bands of hbNaph appear in a shorter wavelength region below 310 nm, compared to those of BINOL, and its fluorescence is in the invisible UV region. However, increasing the concentration of hbNaph in solution up to 0.1 M results in its absorption edge gradually extending to longer wavelength, with a shoulder around 330 nm, and finally increasing to about 450 nm. At the same time, blue fluorescence is clearly observed, as well as a new CD band with the sign of the Cotton signals reversed from those obtained for dilute solutions. These results suggest that, at high concentrations, hbNaph forms chiral aggregates, in which π-electrons are delocalized over multiple molecules. To further understand how molecular axial chirality is transformed to supramolecular chirality, we attempted to construct aggregate models by simulating CD spectra using a time-dependent density functional theory. The only reasonable model obtained was that involving the counterclockwise R-enantiomer forming a clockwise helix, while the clockwise S-enantiomer forms a counterclockwise helix. We conclude, however, that, for such helixes, the most plausible model is densely packed and forms when the dihedral angle between the two phenol rings of hbNaph is acute, at around 75°, which reproduces the aggregate-induced CD sign inversion.

Moon-like Facies by Glucocorticoid Is Associated With the Development of Diabetes and Body Image Disturbance.

Context: Moon-like facies (MLF) are a typical side effect of glucocorticoid (GC) therapy; however, its predisposing factors, relationship with GC-induced complications, and effects on body image are not well understood. Objective: This study aimed to determine the predisposing factors for MLF during GC therapy; its association with GC-induced diabetes, hypertension, and dyslipidemia; and its effects on body image. Methods: This prospective observational study spanned 24 weeks and targeted patients who received GC therapy at the University of Yamanashi Hospital from June 2020 to August 2022. The MLF was defined based on the following 3 factors: (1) an increase in facial measurement lengths, (2) subjective facial changes by patients' self-assessment using a visual analog scale; (3) objective and qualitative facial changes assessed by physicians. We examined the predisposing factors for MLF and the association of MLF with GC-induced diabetes, hypertension, dyslipidemia, and body image. Results: The cumulative incidence rate of MLF at 24 weeks was 37.6%. Predisposing factors for MLF were an initial oral prednisolone dosage of ≥ 30 mg/day [odds ratio (OR) 63.91, 95% confidence interval (CI) 5.82-701.81] and female (OR 6.66, 95% CI 1.35-32.79). MLF showed a significant association with the onset of GC-induced diabetes (OR 6.58, 95% CI 1.25-34.74). MLF was also an independent factor contributing to body image disturbance (ß = -18.94, P = .01). Conclusion: MLF contributes to body image disturbance and is associated with the development of GC-induced diabetes; therefore, it is clinically important as a physical manifestation of GC therapy.

Protein nanoarrays using the annexin A5 two-dimensional crystal on supported lipid bilayers.

Protein nanoarrays are regularly ordered patterns of proteins fixed on a solid surface with a periodicity on the order of nanometers. They have significant potential applications as highly sensitive bioassays and biosensors. While several researchers have demonstrated the fabrication of protein nanoarrays with lithographic techniques and programmed DNA nanostructures, it has been difficult to fabricate a protein nanoarray containing a massive number of proteins on the surface. We now report the fabrication of nanoarrays of streptavidin molecules using a two-dimensional (2D) crystal of annexin A5 as a template on supported lipid bilayers that are widely used as cell membranes. The 2D crystal of annexin A5 has a six-fold symmetry with a period of about 18 nm. There is a hollow of a diameter of about 10 nm in the unit cell, surrounded by six trimers of annexin A5. We found that a hollow accommodates up to three streptavidin molecules with their orientation controlled, and confirmed that the molecules in the hollow maintain their specific binding capability to biotinylated molecules, which demonstrates that the fabricated nanoarray serves as an effective biosensing platform. This methodology can be directly applied to the fabrication of nanoarrays containing a massive number of any other protein molecules.

Fundamental and higher eigenmodes of qPlus sensors with a long probe for vertical-lateral bimodal atomic force microscopy.

The detection of vertical and lateral forces at the nanoscale by atomic force microscopy (AFM) reveals various mechanical properties on surfaces. The qPlus sensor is a widely used force sensor, which is built from a quartz tuning fork (QTF) and a sharpened metal probe, capable of high-resolution imaging in viscous liquids such as lubricant oils. Although a simultaneous detection technique of vertical and lateral forces by using a qPlus sensor is required in the field of nanotribology, it has still been difficult because the torsional oscillations of QTFs cannot be detected. In this paper, we propose a method to simultaneously detect vertical and lateral force components by using a qPlus sensor with a long probe. The first three eigenmodes of the qPlus sensor with a long probe are theoretically studied by solving a set of equations of motion for the QTF prong and probe. The calculation results were in good agreement with the experimental results. It was found that the tip oscillates laterally in the second and third modes. Finally, we performed friction anisotropy measurements on a polymer film by using a bimodal AFM utilizing the qPlus sensor with a long probe to confirm the lateral force detection.

Impact of Reconstructing Intercostal Artery on Spinal Cord Circulation During Open Surgery for Thoracoabdominal Aortic Aneurysm

ABSTRACT Introduction: We evaluated the outcomes of the selective intercostal artery reconstruction for preventing spinal cord injury during thoracoabdominal aortic aneurysm repair. Methods: We retrospectively assessed 84 consecutive patients who underwent thoracoabdominal aortic aneurysm repairs between 2004 and 2016. The mean age of the patients was 57.3 years. We performed preoperative multidetector computed tomography in 74 patients (88.0%) to identify the Adamkiewicz artery. Spinal cord injury preventive measures included motor evoked potential monitoring, hypothermia induction, Adamkiewicz artery or other intercostal artery reconstruction, and cerebrospinal fluid drainage. Results: The hospital death rate was 5.9%, and paraplegia occurred in four patients (4.7%). The Adamkiewicz artery or other intercostal arteries were reconstructed selectively in 46 patients (54.7%). Of these patients, 41 underwent postoperative multidetector computed tomography, which revealed occlusion of the reconstructed grafts in 23 patients (56.0%). There was no paraplegia in the patients who underwent reconstruction of the Adamkiewicz artery, which was patent on postoperative multidetector computed tomography. Univariate analysis showed no significant effect of various risk factors on the development of spinal cord injury. Conclusion: Outcome of open surgery for thoracoabdominal aortic aneurysm in our institution regarding spinal cord injury was satisfactory. The benefits of Adamkiewicz artery reconstruction remain inconclusive, and further larger studies are required to identify its validation for spinal cord protection in thoracoabdominal aortic aneurysm repair.

Defining the optimal historical control group for a phase 1 trial of mesenchymal stromal cell delivery through cardiopulmonary bypass in neonates and infants.

OBJECTIVE: The Mesenchymal Stromal Cell Delivery through Cardiopulmonary Bypass in Pediatric Cardiac Surgery study is a prospective, open-label, single-centre, dose-escalation phase 1 trial assessing the safety/feasibility of delivering mesenchymal stromal cells to neonates/infants during cardiac surgery. Outcomes will be compared with historical data from a similar population. We aim to define an optimal control group for use in the Mesenchymal Stromal Cell Delivery through Cardiopulmonary Bypass in Pediatric Cardiac Surgery trial. METHODS: Consecutive patients who underwent a two-ventricle repair without aortic arch reconstruction within the first 6 months of life between 2015 and 2020 were studied using the same inclusion/exclusion criteria as the Phase 1 Mesenchymal Stromal Cell Delivery through Cardiopulmonary Bypass in Pediatric Cardiac Surgery trial (n = 169). Patients were allocated into one of three diagnostic groups: ventricular septal defect type, Tetralogy of Fallot type, and transposition of the great arteries type. To determine era effect, patients were analysed in two groups: Group A (2015-2017) and B (2018-2020). In addition to biological markers, three post-operative scoring methods (inotropic and vasoactive-inotropic scores and the Pediatric Risk of Mortality-III) were assessed. RESULTS: All values for three scoring systems were consistent with complexity of cardiac anomalies. Max inotropic and vasoactive-inotropic scores demonstrated significant differences between all diagnosis groups, confirming high sensitivity. Despite no differences in surgical factors between era groups, we observed lower inotropic and vasoactive-inotropic scores in group B, consistent with improved post-operative course in recent years at our centre. CONCLUSIONS: Our studies confirm max inotropic and vasoactive-inotropic scores as important quantitative measures after neonatal/infant cardiac surgery. Clinical outcomes should be compared within diagnostic groupings. The optimal control group should include only patients from a recent era. This initial study will help to determine the sample size of future efficacy/effectiveness studies.

Dose Effect of Mesenchymal Stromal Cell Delivery Through Cardiopulmonary Bypass.

BACKGROUND: Neurologic impairments are a significant concern for survivors after pediatric cardiac surgery with cardiopulmonary bypass (CPB). We have previously shown that mesenchymal stromal cell (MSC) delivery through CPB has the potential to mitigate the effects of CPB on neural stem/progenitor cells. This study assessed the dose effects of MSCs. METHODS: Piglets (n = 20) were randomly assigned to 1 of 4 groups: control, CPB, or CPB followed by MSC administration with low and high doses (10 × 106 and 100 × 106 cells per kilogram). We assessed acute dose effect on cell distribution, multiorgan functions, systemic inflammation, microglia activation, and neural stem/progenitor cell activities. RESULTS: By magnetic resonance imaging, approximately 10 times more MSCs were detected within the entire brain after high-dose delivery than after low-dose delivery. No adverse events affecting hemodynamics, various biomarkers, and neuroimaging were detected after high-dose MSC delivery. High-dose MSCs significantly increased circulating levels of interleukin 4 after CPB. Both MSC groups normalized microglia activation after CPB, demonstrating MSC-induced reduction in cerebral inflammation. There was a significant increase in neuroblasts in the subventricular zone in both treatment groups. The thickness of the most active neurogenic area within the subventricular zone was significantly increased after high-dose treatment compared with CPB and low-dose MSCs, suggesting dose-dependent effects on the neurogenic niche. CONCLUSIONS: MSC delivery through CPB is feasible up to 100 × 106 cells per kilogram. MSC treatment during cardiac surgery has the potential to reduce systemic and cerebral inflammation and to modulate responses of an active neurogenic niche to CPB. Further investigation is necessary to assess the long-term effects and to develop a more complete dose-response curve.

Mesenchymal Stromal Cell Delivery Via Cardiopulmonary Bypass Provides Neuroprotection in a Juvenile Porcine Model.

Oxidative/inflammatory stresses due to cardiopulmonary bypass (CPB) cause prolonged microglia activation and cortical dysmaturation, thereby contributing to neurodevelopmental impairments in children with congenital heart disease (CHD). This study found that delivery of mesenchymal stromal cells (MSCs) via CPB minimizes microglial activation and neuronal apoptosis, with subsequent improvement of cortical dysmaturation and behavioral alteration after neonatal cardiac surgery. Furthermore, transcriptomic analyses suggest that exosome-derived miRNAs may be the key drivers of suppressed apoptosis and STAT3-mediated microglial activation. Our findings demonstrate that MSC treatment during cardiac surgery has significant translational potential for improving cortical dysmaturation and neurological impairment in children with CHD.

Molecular-Resolution Imaging of Interfacial Solvation of Electrolytes for Lithium-Ion Batteries by Frequency Modulation Atomic Force Microscopy.

Solvation structures formed by ions and solvent molecules at solid/electrolyte interfaces affect the energy storage performance of electrochemical devices, such as lithium-ion batteries. In this study, the molecular-scale solvation structures of an electrolyte, a solution of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in propylene carbonate (PC) at the electrolyte-mica interface, were measured using frequency-modulation atomic force microscopy (FM-AFM). The spacing of the characteristic force oscillation in the force versus distance curves increased with increasing ion concentration, suggesting an increase in the effective size of molecules at the interface. Molecular dynamics simulations showed that the effective size of molecular assemblies, namely, solvated ions formed at the interface, increased with increasing ion concentrations, which was consistent with the experimental results. Knowledge of molecular-scale structures of solid/electrolyte interfaces obtained by a combination of FM-AFM and molecular dynamics simulations is important in the design of electrolytes for future energy devices and in improving their properties.

The Japanese version of the Generalized Problematic Internet Use Scale 2 (GPIUS2): Psychometric evaluation and analysis of the theoretical model.

BACKGROUND: The Generalized Problematic Internet Use Scale 2 (GPIUS2) is a self-administered questionnaire that evaluates problematic internet use (PIU) from a multidimensional perspective. We analysed the psychometric properties and adequacy of the theoretical model of Japanese version of the GPIUS2. METHODS: This study included 291 healthy Japanese adults (median age = 25 years; interquartile range 22-43 years; 128 women) who completed the GPIUS2 and several other questionnaires evaluating the degree of PIU, self-esteem, depression, and impulsivity. RESULTS: Exploratory factor analysis (EFA) revealed a similar factor structure between the original and Japanese versions of the GPIUS2, with only minor differences in item composition. Higher-order confirmatory factor analyses revealed a good overall fit for the factorial model suggested by EFA, indicating adequate construct validity. The model showed acceptable internal consistency. Partial correlation analyses between GPIUS2 and other measures, with age as a control variable, revealed good convergent validity. Finally, structural equation modelling showed a good fit to the data, supporting the cognitive-behavioural model of Caplan (2010). CONCLUSIONS: The Japanese version of the GPIUS2 has good psychometric properties and the theoretical model of the original GPIUS2 is applicable to Japanese adults.

Online Behaviours during the COVID-19 Pandemic and Their Associations with Psychological Factors: An International Exploratory Study.

This cross-sectional study aimed to explore specific online behaviours and their association with a range of underlying psychological and other behavioural factors during the COVID-19 pandemic. Eight countries (Italy, Spain, the United Kingdom, Lithuania, Portugal, Japan, Hungary, and Brazil) participated in an international investigation involving 2223 participants (M = 33 years old; SD = 11), 70% of whom were females. Participants were surveyed for specific type of Internet use severity, appearance anxiety, self-compassion, and image and use of performance-enhancing drugs (IPEDs). Results were compared cross-culturally. The mean time spent online was 5 h (SD = ±3) of daily browsing during the pandemic. The most commonly performed activities included social networking, streaming, and general surfing. A strong association between these online behaviours and appearance anxiety, self-compassion, and IPEDs use was found after adjustment for possible confounders, with higher scores being associated with specific online activities. Significant cross-cultural differences also emerged in terms of the amount of time spent online during the initial stages of the COVID-19 pandemic.

Surgical Outcomes in Children With Partial and Transitional Atrioventricular Septal Defect.

BACKGROUND: This study aimed to evaluate the long-term outcomes of partial and transitional atrioventricular septal defect repair, focusing on left atrioventricular valve reoperation. METHODS: We conducted a retrospective review of 104 children who underwent partial or transitional atrioventricular septal defect repair between August 1983 and January 2021. The major outcomes included patient survival and left atrioventricular valve reoperation. RESULTS: Median age at repair was 4.0 (0.1-17.0) years, with 17 patients being infants (age ≤ 1 year; 16.3%). All but eight patients (92.3%) underwent left atrioventricular valve cleft closure. After initial repair, there were 18 cases of moderate-to-severe left atrioventricular valve regurgitation (17.3%). Three in-hospital deaths (2.9%) and four late deaths (3.8%) occurred. At follow-up (median 14.3 years), actuarial survival was 95.1% and 93.0% at 1 and 20 years, respectively, and 16 patients (15.4%) had undergone a total of 19 left atrioventricular valve reoperations. Initial repair performed during infancy was associated with significantly higher mortality than a repair performed after infancy (35.3% vs 1.5%, P < .01, hazard ratio = 26.4). On multivariable analysis, repair during infancy was associated with mortality (P < .01, hazard ratio = 27.4, 95% confidence interval = 2.7-283). Partial or no cleft closure of left atrioventricular valve (P = .03, hazard ratio = 4.7, 95% confidence interval = 1.2-18.8) and moderate-to-severe left atrioventricular valve regurgitation after repair (P < .01, hazard ratio = 9.9, 95% confidence interval = 3.0-32.2) were associated with left atrioventricular valve reoperation. CONCLUSIONS: Partial and transitional atrioventricular septal defect repair outcomes were generally satisfactory. However, repair during infancy had worse survival outcomes, and moderate-to-severe left atrioventricular valve regurgitation after a repair was associated with future left atrioventricular valve reoperation.

Antidiabetic effects of hydroxychloroquine in two Japanese patients with systemic lupus erythematosus.

Hydroxychloroquine (HCQ), an antimalarial drug, is recommended for all patients with systemic lupus erythematosus (SLE), and is widely used around the world. HCQ has various beneficial effects, including antidiabetic effects but was unavailable in Japan until gaining approval for SLE treatment in 2015. We present herein the cases of two Japanese women with SLE and diabetes mellitus (DM) who were treated using HCQ and achieved reductions in glycosylated hemoglobin (HbA1c). A 48 year-old Japanese woman with SLE and DM (patient 1) received oral HCQ at 200 mg/day for the treatment of lupus nephritis. HbA1c levels decreased from 7.2-6.2% after 14 months of HCQ without any loss of body weight or alterations in doses of glucocorticoid or hypoglycemic agents. A 64 year-old Japanese woman with SLE and DM (patient 2) received oral HCQ at 200 mg and 400 mg on alternate days for the treatment of erythema. She also received intensive insulin therapy. HCQ drastically reduced both HbA1c levels, from 10.3 to 7.5%, and the insulin doses required without altering the doses of glucocorticoid or hypoglycemic agents, although body weight increased slightly. No episodes of hypoglycemia were seen in either patient. HCQ can achieve antidiabetic effects in Japanese SLE patients.
